Re: I2C Interrupt
I don't use FreeRTOS I use bare-metal. I want to use I2C Interrupt. What can I do? Can you clarify what you mean by 'bare-metal'? Why do you want to not 'use FreeRTOS'? All the IDF drivers make use of FreeRTOS functionality internally. If you don't want that, you can't use the IDF drivers. I hope m...

Re: I2C Interrupt
As I said, I see two main issues with this code: 1) You can't allocate the I2C interrupt to your own handler and use the IDF's I2C driver, and 2) you cannot call i2c_master_cmd_begin(...) from an ISR. And possibly 3) I2C will not do anything (interrupt...) while the master isn't actively performing...

I tried with this code but I don't work. When I send a value I can't read . #include <stdio.h> #include...

I2C Interrupt
Hi,
I want to use I2C interrupt on esp-idf. What can I do? I couldn’t find any examples. (bare-metal)

SH1122 Library
Hi, I have a problem with SH1122 display. I can't find any library on ESP-IDF and I couldn't write new library. I found STM-HAL library and I tested with my SH1122 board, It works. I changed STM-HAL library for ESP-IDF but It doesn't work and I can't fix. How I can fix ? this is my main.c #include <...
