Hi,
I think it is a bit easier to send or receive emails using a mini pc like a Raspi than using a mcu like the Teensy.

Hi Julien,
i can't answer your question. But the module has wifi. May be OTA programming makes sense?
Hello blazarious,
have you tried to retrigger your timer in the callback function? I do this with GPT2 on a Teensy 4 without any problems like:
void callback() {
if (intervalTime...
And here comes the answer. I have tried different types of timers with no success. All kinds of calling the AudioPlayQueue from an interrupt are leading to problems.
So i decided to link the...
To be sure that audio is working correctly with the transmit interval of 2700 microseconds and 24MHz cpu clock i have added usb outs
and generated a sine wave in the sample buffer:
/* Teensy...
Ok i guess i'm a bit closer to the issue.
I changed the cpu speed to the minimum of 24MHz.
That's the result with an interval of 2700 microseconds:

Hello DD4WH,
thank you for your answer and your recommendations.
I already took a look at your example. But in my case there is no need for realtime processing.
I just want to record audio into...
Thank you Pete!!! In my actual project on a Teensy 3.6 i was using AudioOutputUSB and the dummy to use it was AudioOutputAnalog.
After compiling the code and running on a Teensy 4.1 i had these...
Yes you are right. It takes 2.9mS for a block of 128 samples. Thats why i put a delay of 10 mS in the loop.
There should be more than enough time to release all used blocks.
But the library...
I'm tried the same code on a Teensy 3.6 and it's the same behavior.
Hello,
this thread is a bit older, but the problem is still actual.
I tried a simple code without any extras on a Teensy 4.1.
At the defined max of 80 blocks the loop stucks.
I'm using...
Ok i cant test the code with the laser right now. But i have connected some LEDs to a Teensy 3.5 and it seems to be okay.
I will test it with the connected laser-modul in the next few days.
...
Thank you a lot Paul.
I am using pin 23, 22 and 9 at the moment. Thats FTM0. I will try to check the counter overflow by an interrupt.

Nobody has an idea? In pins_teensy.c PWM is generated with TPM or FTM. But to understand the FTM flowcharts and the application notes is really hard.
The use of FTM_SYNC_CNTMAX or FTM_SYNC_CNTMIN...
Hi all. Is there a way to set new pwm values on 3 or more different pin's at the same time?
It's easy to do this for their digital states. But I need that for pwm ( modulating a TTL rgb laser).
