Thank you! Sorry I missed your reply. I will look into the RMT. I am trying to use this to connect into a DMX data stream of a lighting console. The MTBF I think can be handled as an extra stop bit.

Hi @ESP_wangning, do you have any thoughts or suggestions on the best next step to figure this out?

Thank you!

Thank you, but this doesn't seem to align with the code.

From your post UART_STOP_BIT_NUM, which is used to set the length of stop bits, has 4 valid values. 0: 1 bits; 1: 2 bits; 2: 1.5 bits; 3: 3 bits.

From the code I see
https://github.com/espressif/arduino-esp32/blob/master/tools/sdk/esp32s3 ...

In https://www.espressif.com/sites/default/files/documentation/esp32-s3_technical_reference_manual_en.pdf

UART_STOP_BIT_NUM This register is used to set the length of the stop bit; 1: 1 bit, 2: 1.5 bits. (R/W)

Defines stop bits for the URAT to be 1,1.5, and 2

this also aligns with the arduino ...
