Okay, have revised the code, still have one screen sized source buffer and two 320*96px destination buffers, but using just one for the test.

Hello,
For a musical project, I need to find a way to identify simple wooden coins lying on a board.
Say we have :

- on a few cells, I put some wooden...
I found your code in pop_lcd_diff_buff.ino a bit confusing. It seems that you call PXP_Init every time through the loop. I'm not sure it is a good idea to reset the PXP and set the buffers each time through the loop....

Maybe try adding the following to setup() to aid in narrowing down where the crash is occurring (this capability provides info gathered during the crash, but reported as part of the next boot):

Hey Kris, if I don't clear display before then the transponder code just runs on top of its self and turns into a mess.

Glad you got it to compile. I guess now you know how data and directories are arranged for programs/sketches and libraries.
How are you trying to listen to the sounds?
When your teensy crash BEFORE the USB Host library is able to print out debugging messages, there might be a deeper problem than some race-conditions with interrupts. As far as I know, the usb system initializes and...
Again, thanks very much for your help. The intermittent crashing when plugging in must be some timing/threading/race condition? issue. Having USB debug info doesn't help, it crashes before anything comes out to Serial....
Yeah everything that’s in pxp_start was removed from pxp_init, but it only works if everything is in pxp_init.
Super odd but I’ll keep playing with it.
Yeah, the native pin labels are almost like someone at NXP tried to make the most confusing error-prone naming scheme possible. FWIW, I got them mixed up many times in the early days (in 2018) while designing Teensy...

Hi All,
Thank-you in advance for any help / guidance you can provide. I'm having trouble with a custom T4.1.

Did you remove the lines in PXP_Start from PXP_Init? I tried the same thing, but renamed the new function PXP_XStart(), since I already had PXPStart. Every thing seemed to work as expected. Even if I removed the...
Excellent news, glad we got it sorted out. It’s prompted me to improve the documentation for the PR branch (it shows up in the Design Tool), so once it’s in, things should be a bit easier for everyone.
Something odd that I can't figure out:
If I move the following code from PXP_Init() into it's own function (lets call it PXP_Start):
void PXP_Start(){
CCM_CCGR2 |= CCM_CCGR2_PXP(CCM_CCGR_ON);
PXP_CTRL_SET =...
I'm doing some simple raytracing on the Teensy 4.0. That means doing a lot of dot products of normal vectors, so lots of decimals with values from -1 to 1. I've been using single-precision floats, but I don't think this...

Probably OK ... hard to tell without seeing the full path to the folder and a glimpse of its contents. It doesn't need the -main on the end, but I think it doesn't hurt, either.
Oh dear, I have just compiled the copy I downloaded to my PC without any error.
Do you have this line in your code: #include "play_sd_wav.h" // local copy with fixes?
I have just commented it out on my copy and get...
A few things:
please refer to Paul's post and the image I posted to make sure the MTP_Teensy library is in EXACTLY the right path - your image shows that it isn't
double-check you have downloaded and not modified...
Looks like you copied everything that was inside the original MTP_Teensy folder to the Documents/Arduino/libraries folder. But you should have copied the MTP_Teensy folder (with all of its contents) to...
So it should look something like this (click on the image to enlarge it...):

If you find MTP_Teensy inside a "libraries" folder, don't make the mistake of dragging that libraries onto the libraries inside Documents/Arduino. Doing so will result a libraries folder inside the libraries folder. ...
Yep - sorry for my misunderstanding! Now it works like a charme!!!

My condition to print ADC data is if(Wire2.available()). It should print any data valid or not,...
We have been concentrating on the if (Wire2.available() >= 2) { but of course if the ic does not see a request to send then Wire2.available() will always be false.
I see that the adc is addressed relatively early in...
SDA1 and SCL1 are addressed as Wire2.
You need to change line 308 :- if (!bmp.begin_I2C()) { to include the Wire2 assignment.
So something like if (!bmp.begin(BMP3XX_ADDRESS, &Wire2){.
NOTE:
I am not sure...

Personally I'd read all the values into one value (may as well use a uint32_t, it's a 32 bit processor) and then use bitwise operations to calculate all the outputs at the same time.
