Activity Stream

Fixed in https://github.com/h4yn0nnym0u5e/cores/tree/feature/Audio%2Fminor-connection-improvements, and I've put in PR #556 on GitHub. I believe this not only fixes this bug, but also makes it safe to connect and...

Hello, I meet almost the same issue. I have two detected gamepad controllers when I plug my Teensy Lc. Joystick and buttons work in the RetroPie menu but not in the games. I tried all different Joystick codes I found on...

Doh - didn't see the single quotes on the 'ZERO'

So are you asking how to measure a tiny voltage? Or something else?

Hi Wcalvert, thank you for the suggestion, I will try that in the morning. Yeah apologies for the ugly code format, I wasn't sure how to attach it nicely, will do next time. Thanks again, Harry

Ops,, unfortunately again creates up to 100 files...

They are female connectors which connect to male connectors that are soldered.

You know never thought about looking up the ascii character - no wonder I was having a problem - thanks :) So obvious after the fact

Are the yellow and green wires soldered on to the board at the right? It looks like they are jumper wires whose pins might just be pushed into the holes in the board. Pete

When I am talking about adding DC, I am talking through a large value resistance and sensing the voltage division (or shorted to ground). The current through the transducer would be very small. The problem is detected...

I believe you missed myusb.Task() inside your loop() in the "host" code. Also if you could wrap your source code in code tags next time, it would be a lot easier to read.

Out of curiosity I soldered a crystal and end header to my T3.2, hooked up a 3V coin cell and loaded the stripped down and modified version of the TimeTeensy3 sketch shown below. I removed all the time sync stuff (which...

'0' and 48 and 0x30 are all the same thing - the Ascii code for the zero character.

Is the the switch 'VAR' a byte type by any chance? Or something odd confusing the compiler optimization? switch ( VAR&0xF )

Nope: hm01b0_testv3:503: error: duplicate case value case 48: ^ hm01b0_testv3:489: error: previously used here case '0': ^ only wants single characters - maybe redo section for way it...

I saw some hangs leaving Vid mode as well in some combination with ILI9341 - thought it was just an invalid command series but it was there. Some part of the DMA left active doing interrupt spasms?

@mjs513 does the "case 0x30:" work as "case 48:" ? I've got outdoor things to do as well. Spring sun is sprouting trees in deck cracks and a pickup firewood to unload. I did GIT that ST7735 lib ... Would be nice...

@KurtE Just gave your 'V' mode a try with the ST7789 and.... 1. Sparkfun config - worked very nicely, however when I exited video mode the TMM was basically hung. Could not enter any other commands and had to do a...

Seems to me, by using the pins-mux pdf found by following the link "A larger, more detailed pinout chart" etc. (and the reference manual), that those CS-pins mentioned for the SPI1 (or LPSPI3 in the mux-pdf or reference...

Sorry, I couldn't add the photos in the previous post. Here's the overall setup:

Afternoon all @KurtE - looks like you been busy this morning and afternoon between the new board design and fixing ST7735 lib. Kind of been a bit distracted with running errands again and in backyard :) Will give it...

Thank you, Phil for your comments. I can understand and follow your comments very well. Last year I even gave up with microcontrollers and used a system called Blumat, which worked more or less but needed adjustment...

The Teensyview has solder jumpers so that you can change some pin assignments. You can eliminate the reset function which is on pin 15 (A1) by changing the solder jumper to pin #2. You can modify the D/C function on...

I think you are confused as to how the Teensy and RTC work. Look at this stream https://forum.pjrc.com/threads/63928-Teensy-TimeLib-question?highlight=teensy+rtc If you are using a Teensy 3.2 you have soldered a...

Thanks so much, Frank and Paul. ~50% cpu will be great!

Quick answer: No.

I tried! 1. Run TimeTeensy3.ino. Teensy display right time and date! For ex. 21:02:34 14 4 2021 OK ! 2. I put setTime(0); into setup loop. Reload TimeTeensy3.ino. The serial monitor display 0:00:00 1 1 1970 OK!...

Here's my code and a photo of my setup. The wires on the right side are not connected to anything, they were for connecting to a stepper but I've removed that feature just to get the scale working. The serial port was...

I am certainly not an expert on these things, but I have been doing a deep (theoretical) dive on MCU based timing things before, and collected some (someone else's) ideas and points along the way. Some points out of my...

@all I just pushed up a new st7735_t3 branch: https://github.com/KurtE/ST7735_t3/tree/t4x_dma_no_copy With the WIP code, that appears like it might be working on Micromod with the V command. Note, will need to...

The RA8875 5" with GSL1680 controller is quite simple, build many projects with this RA8875 display. Best regards, Johan #include <SPI.h> #include <RA8875.h> #include <GSL1680.h> #define TC_INT 8

I will probably testing soon, had a few diversions this morning. Like, my updates to FlexIO was incomplete, I was in the process of saying there are 8 timers and shifters not just 4... But some of the tables were not...

This immediately suggests rail bounce (inductance of the wiring causing a spike or ringing on sudden current changes) There should be decoupling at both ends of a power cable to quell this tendancy - if this is...

a couple of very silly mistakes on my part, but fixed either grab the new .h and .cpp files. or I can indicate the lines to edit in these files.

There is a variety of ways, also several topics on this: Some of this is sort of mentioned on the Teensy 4.1 product page: https://www.pjrc.com/store/teensy41.html#software a) you could use makefiles. You can...

Yes.. I think so :cool:

It will depend when the PWM is enabled w.r.t. the clock driving the PWM unit I think - the way PWM units work is that the output change is triggered by exact matches of the counter register to the PWM value register -...

Weird, yeah don't add a DC offset to any speaker. That's a bad idea.

It means add. I've heard this terminology especially when discussing oscillograms

What do you mean by "ride"?

Adding DC to the headphone out isn't advised, it'll risk pushing the transducer cone to the end-stops. Why do you need to detect the difference? Is it to set different levels or some such? Or to disable the right...

I'm sure Andre is a great guy, but Jeannie needs some new friends out here in California!

My friend Andre is busy soldering. I'm curious .. Soldering the components shouldn't be a problem. I hope the SMD pads are not too small and can be soldered well. :) Example of the first case

Look in the teensy libraries for TimeTeensy3.ino!!

Thank you so much. We are required to read the raw data and store them as files in the cloud, for now; so that they can later be used for analysis.

Meanwhile there is an official Arduino support based on mbed. https://github.com/arduino/ArduinoCore-mbed

it's probably possible, that is, there is sufficient computing power available. But how much Library development are you willing to do, to avoid using the Teensy 4? Why not just use a Teensy? The libraries are...

I have looked at sensing soil moisture to control irrigation off and on for 20+ years. I think it is a quixotic quest. Even if you could create a perfect sensor (inexpensive, long lasting, reliable, easy to calibrate)...

My knowledge may be outdated, but as far as I remember the Pico can do either audio-in or audio-out, but not both. You would also have to see if it can provide mclk for the SGTL. In the meantime there is an...

Many thanks, with the 1.5.4#7 compiled well. should i connect T4 to Pin9 and Pin13 like the T3?

No idea how to "reset" Teensy RTC, to set a new time ? Thanks.

Good luck @KurtE. Be interesting see how it works. Thinking about changing the name of the test sketch in prep for release to: HM01B0-KitchenSink :) Then start breaking some of the code out for demo purposes. ...

Thank you for the info, Paul. I was thinking of using the Pico to build a very rudimentary walkie-talkie using the teensy audio board. Just transmitting voice from a microphone to another device and playing it to...

I've not heard of anyone has writing code for Pico to work with Teensy's audio shield. I did see a few people working on generic audio stuff (not specifically for SGTL5000 or this shield) but it looked like a pretty...

SPIFIFO isn't really recommended anymore, but I decided to give it a quick try just to see how much of the CPU time on a Teensy 3.2 would remain unused if an IntervalTimer uses it every 5 microseconds. Here's the...

I know, and I am using the Teensy :). I was just wondering if anybody already has the code.

Would be easier and save much time to just use a Teensy ;)

Yep - Will hopefully figure out what the syncing up is... Yesterday, I made a first pass of code editing to ST7735/89 DMA code. Need to start testing. First need more coffee, and head to town and ...

Is it possible to make the Rpi Pico work with the Teensy audio adapter? (input and output) I am thinking it probably is, using the PIO, but it is beyond my level of knowledge :) If yes, does anybody have any code...

Hi, use transfer(void *buf, size_t count) - that's the fastest.

I recommend to install the TyTools to upload & monitor. You can integrate it to VisualTeensy in the settings tab.

You would need a debug probe like a JLink and the corresponding GDB server to make this work. Plus you need to modify the hardware of your Teensy to be able to connect this probe. You find some information and a link...

..and..can you show us a photo? Is everything soldered?

The last PR incorporated from @KurtE included the 'V'ideo command. Tested with both Sparkfun and non-Sparkfun. Only thing is for DMA video/continuous it does take a while for the image to synch into a image stream...

Good Morning all Just gave our latest set of updates a spin. Tested the same as @defragster and agree all is working well. The only thing not tested was the 'z' command.

This is the USB Serial. You may want to try Serial2 :-) If that doesn't solve the problem, you'll have to show us some code - or better, all the code. It needs to be broken down to a minimalistic example.

I activated the "Debug support" window at the visual teensy and generated a new project, But when activating "Start Debugging" using F5, it advised that is needed the Cortex-Debug I found it here:...

Yes, there is a solution. All you need to do is use a recent beta version, because PDM support for Teensy 4.x was added after 1.53 was released. Get it here:...

Dear Community, i get the same compiling error as the thread starter in first post. is there already a solution? If i read correctly the work is still going on? - is it? i am using a different chip ( not MP34DT01-M...

"V" works SO SMOOTHLY! it only works USE_SPARKFUN - comes up Very Dark without a good "Calibrating Auto Exposure" it seems, and at times it comes up iffy for a bit, one time it was running and went more like that odd...

Thank you! Having found that little ‘plug’ it works fine now and I feel a bit like an idiot! 😀

Saw the PR to mjs513 was taken -testing: //#define USE_SPARKFUN 1: SEEM GOOD :: s, c, D, f, F :: i.e. no signs of tearing or skewing or shift offset in the ILI9341 image "d" :: (before FlexIO) DMA cont repeated...

Playing around with a Horizontal slider and discovered that Snap doesn't seem to work and while setting up this example code found artefacts to do with handleShape(5) - only. And the code:- #include...

All Had a strange thought - not sure where it came from must have been a nightmare. With the lack of PSRAM on the MM board is there a way to use the SDIO pins to simulate having a PSRAM and maybe telling the core to...

Good luck @KurtE. Will keep using the ILI9341 then perhaps swap to the ST7789 when your new work is done. Not sure what is up with 'z' - it can work - but sometimes just aborts it seems. Also REALLY odd the...
