ESP32 as i2c slave in NONFIFO mode with addressed i2c RAM

Postby SiTLOOMS » Sat Jul 16, 2022 7:36 pm

I want to use ESP32 i2c with the addressed RAM, as shown in Figure 61 at page 287 of ESP32 Technical reference manual .
But as far as I get ESP-IDF i2c driver only provides FIFO mode.
Previously at this pade mentioned that to use i2c with addressed RAM I need to set I2C_FIFO_ADDR_CFG_EN register and set I2C_NONFIFO_EN register. But I never found associated functionality in i2c driver.
So, the question is: does anyone used ESP32 i2c-slave this way? If so, can you please provide me with a code example? Or maybe point me a search direction so I could do it myself?

Sorry for my english.
