I went overboard putting a 50K resistor on each IO pin, and stepping up voltage each day by 5V. So far so good. No more death.

no, this is another board we built for our camera application. The same NXP 1062 is used. I would have used Teensy if UVC is implemented on Teensy.

Trying to write to the flash, I had all kinds of instability issue. I finally have to relocate almost all the code to memory. The complication in my case is the use of FreeRTOS. It doesn't seem to recover properly after...

I didn't ask this question in NXP forum. But the response there usually takes days, not like hours here.

Paul, I think you just pointed out the problem. I copied the code from https://www.pjrc.com/teensy/td_serial.html, and didn't notice the bytecount is defined as unsigned char, while the available byte counts can be...

Ok I think the problem is SerialUSB1.readBytes() itself. I am sending a big chunk of 32K bytes from pc. int handleDataTransfer(){ unsigned char bytecount = 0; int rd=SerialUSB1.available(); if(...

This has exactly the same speed. It can't read too many bytes each time also. Is there source code available? I suspect internally SerialUSB1.readBytes calls SerialUSB1.read() many times in a loop. int...

Is there any way to speed up the Serial.read()? From what I can see on the TESTPin, the while loop run 5 to 6 times each micro seconds. If we can find out how many bytes available, can we use a memcpy to get all the...
