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...

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
...

@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...

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...

@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...

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...

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...

@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...

@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...

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...

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...

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...

@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...

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...

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...

@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...

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)...

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? ...

Morning @KurtE
Actually thought about it but forgot. Remember what they say about assume.

UPDATE: It works:

Acc [mg]: 21.0 x, -37.0 y, 1055.0 z, 27.5C
Acc [mg]: 21.0 x, -34.0 y, 1059.0 z,...

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...

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...

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...

@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...

@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. ...

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...

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...

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...

@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...

@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):

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...

@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...

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...

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:

//...

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:

@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...
