As usual yes it make sense when you explain it - I just need to do some more homework on the TCD setups. Going to be a long process.

No problem - been doing some other things as well. Just when I get back on I'm on for a while. Been spending time going down the rabbit hole. Funny that's exactly what I am seeing with FlexIO. With...

Looking the schematic I see that you have MISO/MOSI shared between the touch and LCD. Can't remember but you may have a tristate buffer issue. Take a look at step 2 of PJRC's Better SPI Bus Design in 3 Steps. You...

@Paul - @KurtE The more I read the more confused I get. Was looking at AN12686, pg13 and what @KurtE was DMA stuff. On pg 13 for DMA setup the last 2 bullets: • Last destination address adjustment: 0, which means no...

@defragster Going to put the timings back in since I know what to expect now. Was driving me crazy when it FPS going down to 16 but think that was display connection issue

Set up releases for the library and that code is permanently there as Release v1.0.0. The flexIO changes will be in v1.1 I guess. Just trying to keep what works.

@defragster Also think the timing prints were getting me confused. Also playing with some settings for brightness and exposure. With the lights on my image tended to be basically showing glare. Went to the openmv...

@defragster Think I was running into the problems you just described plus issues with the display connections. Also I changed the "F" movie function to this if ( g_continuous_flex_mode ) { ...

As they say keep dreaming :) Just tried it on the ST7789 and seems to be working there as well. Although trying to use for video don't work too well. Works a bit better on 9341. Think maybe it will work better...

Think I agree - doesn't make sense to keep DMA using GPIO. To be honest I would hold off on trying to get it working with GPIO for the HM01b0

@PaulStoffregen Was going through your DMA code (you guys are bringing me down another rabbit hole with DMA) :) Anyway think this is the function that controls dma h/w trigger: // Use a hardware trigger to make...

Thats strange, I only get that when my pin assignment is off - know this is going to be a silly question but did you remember (1) to change the pin assignments in the graphicstest, and (2) make sure you have ILI9341...

Here's what I am using as of this morning after your changes:

PR was merged. Just downloaded it and see what you mean. Started reading FlexIO once :) Guess I will have to pull the manual out again. For some reason having trouble with @defragsters sketch - not sure why so...

Merge done.

@Paul - @KurtE - @defragster Did a couple more tests with FlexIO. Test 1: Tried changing the frameRate from 30fps to 60fps. At 30 "F" (flexIO continuous) using @defragster's updated sketch, runs fine picture quality...

Morning All Merged the changes into the github repository and just start playing but my display is acting up - wire connections with jumpers Argh! Anyway ran 'f'lexio using Sparkfun and non-sparkfun configs. Both...

Was thinking that maybe need to lower the SPI Clock setting

Was just about to post - but the other one should have worked as well. Going to delete it - probably easier that figuring out the differences.

Should just need ILI9341_t3n library. 's' is pretty standard and seems to have always worked. The latest TMM-HB01B0-Camera is set up for 324x224 but 's' works for Sparkfun or non-Sparkfun configs. I know every...

Probably not the problem but wanted to ask. In the .h file enum {DMABUFFER_SIZE=1280}; // 640x480 so 640*2*2 the 1280 probably needs to be changed to 324*2*2 = 1296

Cool. Sounds like you had fun planting - rainy and cold here so good day to stay inside.

Just tested the mods I just made and it works :) You want me to push it to you or you can just use what you have - probably the same since I just copied it from ILI9341_t3n

Just made the changes for 8 and 4 and was going to try out - should have known better :) EDIT: Is it posted - I will give it a try

@KurtE Looks like we are going to have to edit the ST7789 library to add in read8pp as well since I don't think it currently supports it.

Easy answer - yes. See page 16.

That was the change from last night and this morning. So yes first 2 pixels and last 2 pixels. Edit: Kurt's original DMA code skipped the 1st 4 pixels and what I went to this morning was using the subwriteRect that...

With the change that Kurt made to the 's' decided to see if the other frameSizes would work as well: /* * FRAMESIZE_INVALID = 0, * VGA Resolutions * FRAMESIZE_QQVGA, // 160x120 * FRAMESIZE_QVGA, ...

@Paul Very cool that you got some life with using FlexIO. Was looking at Kurt's lib this morning and my head hurt :). Oh just one thing the 4pixels is a 2 pixel border around the actual 320x240 image. A quick...

Yeah was going way deeper originally to see what was going on so started with Vsync. Want to see what you did and see I can merge but really distracted. I did remember to update the PDE to 324/244 though. But to...

@KurtE Updates are already pushed to repository, see post 342, right before yours. 99% sure that the writeSubImageRect is working correctly because I am now using it for 's'napshot and 'continuous modes and its...

Just pushed the current changes using subWriteRect and QVGA = 324x244. One other thing - took setpixformat out of the sketch and called it directly from init since this camera only supports grayscale. Also added a v2...

Morning @KurtE Yep - tried just making _frame_ignore_cols = 0 but the image messed up. Agree - not sure why you are multiplying by 2 since we only have grayscale. The *2 in the original readFrame was for color...

@KurtE I found the issue that you were having with having to skip 4 pixels. Turns out that the actual image size for QQVGA is 324x244 and not 320x240. The extra 4 pixels seem to be just border pixels. So I tested...

@KurtE - @Paul - @defragster - @all More discoveries, realizations and decisions. Doing some digging it appears that the framerate is dependent on 3 settings: 1. clock - osc_div which is done we use the function...

Just to satisfy my curiosity I put back into the loop Paul's vsych timing code and sure enough, whatever combination of settings Sparkfun is using seems off: Using the 6Mhz clock and only changing frameRate to 30 and...

Did a little bit more testing and one thing I noticed is that the framerate when set to 60 seems alot slower using the Sparkfun config rather than the default config. With the default config the osc_div is set to 2B...

Found it. 3, 0xb1, 0x00, 0x10, // FrameRate Control 119Hz its in both the ILI8341_t3 and _t3n libraries.

Hi all @KurtE beat me to it - was going to mention that @KurtE did a lot of work with FlexIO and he a library set up for it - not sure where the whole discussion is on the forum anymore I'll second what Kurt said...

@KurtE Can't seem to push the SPI Clock over 30Mhz for the ILI9341 - just shows a white screen if I do. Just an FYI

I'll go ahead and push the changes I have so we will in synch again. then you can change the handshake. You know never thought about about how fast the screen can update. Don't remember what SPI we defaulted to in...

Thanks for the info and update

@KurtE Changed 2 settings in the default config and DMA seems to be working without using the Sparkfun: {FS_60HZ_L, 0x85}, {FS_50HZ_L, 0xa0}, Give it a try and let me know if I am...

Just merged your PR but looks like DMA mode got worse when not using Sparkfun registers.

Was actually thinking about something like that last night but seems you beat me to it:) Anyway's just did a quick experiment and think the MCLK clock has something to do with it. For the default_regs example I...

@Frank B Ok - I know I can't answer this but curious since I have no idea what it means. Think you are saying that what lib is included its using software to calculate integer divisions when T4 should be doing it...

Nice comparison @KurtE. From the lib I know what some of those settings are and some get changed with the function calls: INTEGRATION_H(202) 2(2) 1(1) INTEGRATION_L(203) 133(85) 2(2) ANALOG_GAIN(205) 0(0) 32(20)...

Was wondering why you set it up to have its own namespace. Is there anyway to do that with in the core. Reason asking it would be simpler than have to add the files to every library or sketch? Does that make sense?

Morning @KurtE Actually thought about it but forgot. Remember what they say about assume. UPDATE: It works: Acc : 21.0 x, -37.0 y, 1055.0 z, 27.5C Acc : 21.0 x, -34.0 y, 1059.0 z, 27.3C Acc : 21.0 x, -34.0 y,...

Good luck with FlexIO for the camera - assuming you mean the 4bit FlexIO? Are you trying it with the library or started it with your initial test sketch - going to assume your initial sketch? If the lib you may have a...

Was testing a couple more things: 15s Restore: Works - tested both on the ATP and ML boards. Quad Encoder Library: Finally got a chance to test change I made to the T4 Quad Encoder library that adds...

On a different note from the HB01B0 camera. Was looking at what @luni did and looking at the pins_arduino.h file and was wondering if it would worth it to add @luni's pinouts to the pins_arduino.h file like this: #if...

@defragster - getting ready for zzzz's but it has to be something on the PC side. I have it hooked up to my powered hub and its working no problem. I did notice that there is a noticable delay between when you hit 'p'...

@KurtE - @defragster - @PaulStoffregen - @All Decided to take a short break from the camera stuff and see if I could get the the ILI9341_t3n library working with the Sparkfun Display/Input board. So, I added the...

Try using the sparkfun config by uncommenting the use_sparkfun at the begging of the sketch. Think I am using 4 in wires with no problem. Ps. Sent about 30 images to the processing sketch from the teensy with no...

Very cool Paul that you got it wired up and its working :) I did incorporate the PR and Thanks for fixing that packed warning message - wasn't sure how to fix that one :) Incorporated your PR with the DMA stuff...

That was the only thing I could think off the top of my head. Will have to test it out again soon. Think for the most part I done with changes now time to have fun with Kurt’s smart stuff and the processing sketch

@defragster You could try changing the baud rate in the processing sketch to something much larger than 9600

@defragster That comment is from the auto calibration function that I extracted from the Sparkfun library. Just tweaked the sketch a bit more after playing with some of the functions and I am not getting that not...

@KurtE You are going to kill me just pushed up some minor changes: 1. fixed pfmt, 2. #define for monochrome sensor and 3. Some tweaks to the sketch Can't wait to see what you did to it :)

You may want to check this video out (Why I put a Teensy in Every Project): https://www.youtube.com/watch?v=75IvTqRwNsE

Almost sure its on the processing side. Had similar problems before with processing. Thought most of it would be resolved if we used USB1.

Actually what I was thinking was to add a define: #define SensorMonochrome 1 to the .h and then wrap the test in a define. Probably will do that on the next update.

@Paul - agree with Kurt - pretty cool to see.

Not sure whats going on - on my machine it seems to be working no problem. After I finish play with the lib and sketch maybe will play with the processing code. Right now I am playing with the different functions in...

@KurtE Was just playing with the fix and something hit me with readframe. The readFram function was designed to support the color version of the HB01B0 camera so once you fix the error with pixformat you wind up with...

Darn it. Fixed it for framesize but forgot to change it for pixformat. Going to fix it now.

About 5minutes after I post the question I remembered that those flags are no longer in use with the SD library. Sometimes hard to remember all the changes :) See the update to the post. Thanks for reminding me. I...

Morning again Running into a little problem. I the past (Buddabrot) I have used this code snippet to increment the file name if the file already existed on the SD card using the SD library: // if name exists, create...

Good morning all Been at it again this morning with the camera library. Made some minor updates to the sketch and pushed them up to the repository. 1. New menu selections: Serial.println("Send the 's' character...

@defragster Something weird. I just responded to this but maybe forgot to hit post. I just retested with stock ili9431 library and am sending frames to the Processing sketch without an issue. Not seeing the same...

I can confirm its not working with the t3n library. On the t3n it sends several frames to the display and then after that screen updates but its all white. On the t3 version it seems to work with an issue.

Ok - video don't work very well with the Processing sketch which you are using. Only can send snapshot to the processing code. Also looks like you never change the image size in the processing sketch. ...

Ok that sounds like something with the ILI9341. Not having any of those problems with the ST7789

That was the reason for using SerialUSB1. I make sure the sketch is running and the image window appears and then send the data from Arduino sketch with p command in main serial window. Did it a whole bunch of times...

thats strange. Assume you are using the _t3n library? In middle of cleaning some stuff up with the code then will hook up a ILI9341 and see whats going on. Maybe this will help you with my convoluted thinking:...

That's strange. I have seen that before during my development but once I fixed the bugs it was working. Assume you define Spartfun 1? Are you using the ILI9341? Have tested with that one yet :)

@KurtE - @defragster Just created the Github repository: TMM-HB01B0 - https://github.com/mjs513/TMM-HB01B0-Camera. Have fun. Don't mind at all. My C++ isn't all that great. Going Boom happens to me all time...

Never having used Processing - is that what the EXTRAS INO is for? That is balking as well - does it need pointer to Teensy on Serial? The extras folder contains CameraVisualizerRayBytes.pde sketch that you run on...

Ok will set up now that I am awake. :)

@defragster On my phone so... anyways they look equivalent. Both spi and 3.3v. To run the processing sketch you need Processing app. You can get it at the Processing.org website. The processing sketch runs on the...

@KurtE - @defragster Ok need a break. Using the processing sketch in your OV7670 lib and dual USB on the TMM this is what I get for a snapshot on the PC: Still have a little to do but here is what I have so far. ...

@KurtE Very cool indeed. Have to add your hack :) to all my hacks in that sketch. Glad its working :) Almost done with getting it send to processing. But need to do some other less fun things

Nice timing just updated. Use the latest - change the framerate if you want smoother video. I noticed that too but haven't got to the 9341 display yet. Want to finish changes to the lib and sketch first then play...

Good Morning all @defragster - glad you got it working with the ILI9341 and its working for you. @KurtE - haven't installed your latest updates to the ST7789 library. Still some stuff to do but I did incorporate...

Now you know why going to update the lib to use the subimage function so it might fix on a small display with smaller resolution. Have several ILI934's, ILI9488's etc. Ready for sleep now so tomorrow have a couple...

Ok - got on the computer to answer. Easier than using the iPhone. Anyway I am using a Adafruit 320x240 ST7789 display for the testing. One because it was handy and more importantly didn't require a 5v pin. For...

yep it’s just plug and play. No mods to the board necessary.
