Re: I2C crash with release/v3.0 - what's an effective way to debug this?

I don't see why it would be a problem. You may want to look at the comments and code here https://github.com/espressif/arduino-esp32/issues/1093

Re: DMA example for UART communication for ESP32

If the baud is 115200 then the tout interrupt will come approx 90us after end of frame.

Re: DMA example for UART communication for ESP32

End of frame will also generate tout interrupt so unless you need ultra realtime processing of messages it should be ok.

We didn't set fifo threshold to 1 byte but set 1 byte as interrupt to get each byte interrupt.

Isn't that the same thing?

Code: Select all

uint8_t rxfifo_full_thresh
UART RX full interrupt threshold.


Why do you need an interrupt for each byte? Default is 120.

Re: DMA example for UART communication for ESP32

The problem is setting fifo threshold to 1 byte
