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 Sometimes...

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. Any...

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

Hi, a beginner here… Could you kindly help me with some question marks related to ESP32-C3-DevKitM-1 and SPI? Here is what I read at https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/peripherals/spi_master.html: ESP32-C3 integrates 3 SPI peripherals. • SPI0 and SPI1 are use...
