btw. this is how to make a sysex file into easy to fix array data(remove the last comma):
hexdump -v $SYSEX_FILE | awk '{print $2$3$4$5$6$7$8$9}' | fold -w 2 | sed 's/^/0x/g' | sed 's/$/\,/g'| tr -d '\n' | fold -w...
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...):
I've done some improvements on the documentation, which you can find at...

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!!!
Many thanks for this - MicroDexed now supports loooooooong delays and some more memory for variables is available. I created a library which can be...
It's less than 32K bytes, so space is probably not an issue, but you need to remove the '\' characters at the end of each line. That's a syntax error. You only need that when you are extending a literal string, or a...

I just tried by adding a delay of 1 sec before Wire2.begin() in setup() and a delay of 1sec after too. It did not help.
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...
Hey all,

Oh, I forgot: If you go the the USBHost_t36.h file and uncomment line 62, you will see a lot of debug messages from the USB Host library. Maybe that might help to locate where it crashes.

Thanks very much for this. It works to ignore the CC data when plugging in and then takes CC data after. However, it's freezing and crashing when unplugging and plugging back in about 80% of the time - it's not...
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.
If you define the pin numbers as an...

It looks as if you've requested to use delay memory fitted to the audio adaptor, but previously you said you put it on the Teensy 4.1 as EXTMEM - try changing that statement to AudioEffectDelayExternal...
I just tried the PR, but unfortunately it does not work. I put a 200ms sine signal into the delay and get nothing (except the original signal). With AudioEffectDelay() everything works... re is the code I used:...
Oh! Now I see what I missed. I am so sorry! You don't want to ignore ALL messages but just the first few one that the controller send on startup!

This is just to confirm that it's working to control my 4 quad digipots. I used to use SPI with CS pins, which worked out to 6 pins total. Nice to see that I can now accomplish the same thing using just 2 digital pins...

I need 4 sessions on mDNS. I saw that this topic is a little old, so I thought there was a possibility that some of you have solved this problem. Thank you very much!
Actually your text displays probably displays for 50 milliseconds. You are clearing the display in the mode selector so your display will get cleared (of course depending on button states). Since your stand by text and...
Yes I want CC messages. I don't want the messages that get sent by some MIDI controllers when they get plugged in and start up - they're irrelevant. Perhaps I should mention that I'm taking MIDI in from USB Host, USB...

Table lookup is one approach, combine the inputs into a single int and do the lookup, then expand for the outputs - the advantage is each logic function just needs a different table, not more coding, the disavantage is...

Note, there are two types of memory that you can solder to the underneath of a Teensy 4.1.
There is PSRAM and flash. Both can be accessed as main memory. These chips use the normal cache, so as long as you are just...
If you really want to pour more time into it, you could remove the NCV8186AMN330TAG and then try externally applying 3.3V. Best to use a current limited lab bench power supply with a limit around 150mA. Even if you...
No, clearDisplay literally clears everything in the video buffer. Noting that this particular display driver uses part of your Teensy memory as the video buffer. I see you have this call in your update_xpndr function....
Thanks Paul. Very good of you. Alas, I already have a replacement Teensy. I just considered fixing the dead one if possible. As it's probably the CPU that's dead, it's probably not worth it. Must be the most expensive...
If you want to attempt replacing the NCV8186AMN330TAG regulator anyway, I'll be happy to give you a spare part at no charge when you order a replacement Teensy 4.1. Just mention this forum thread in the "additional...

Hi Paul,
thanks for the reply, I've seen that example, I was just unsure
as it just uses a normal array with all leds in it.

pretty positive that...
@SteveCS:
It looks like there are some image tools (UTFT), with example sources, included as part of the TeensyDuino installation (located at "C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\UTFT\Tools"...
The regulator on the T4.1 that supplies the 3V3 is short-circuit tolerant.
But the CPU, powered by that same 3V3 regulator, would definitely not be happy with even a momentary 5V on its power pins.
Paul
