Hi,
using ESP32-S3 at 160MHz, I run once per some seconds the code:
gpio_set_level(GPIO_NUM_36, 1);
gpio_set_level(GPIO_NUM_36, 0);
My app runs WiFi, UART and two other lightweight FreeRTOS tasks.
I observe non-consistent width of the "pulse" I generate on GPIO_NUM_36 pin:
Typically: 6.6uS ...

epaper e-ink 2.13" SPI GDEW0213T5 212x104
Hi,
I am struggling a little to find the easiest way how to integrate into ESP-IDF the SPI eink display 2.13" 212x104, coded GDEW0213T5, black and white (branded under "MH-ET LIVE" in my case).
I have tried cale-idf library but I was not sucessful up to now as it does not support the exact type ...

Re: ESP32-C3-DevKitM-1 and SPI questions
OK, just a note:
I am currently using SPI_N=1, polling SPI way and half-duplex and everything seems to work smoothly for INA229.
Still a little curious, however, regarding the original questions
