Hi,
Please confirm whether I2C over DMA is supported by ESP32 or not.
Evolution board which i'm using is ESP32_Devkitc_V4.

In current version, we are still using interrupt to handle sending/receiving data.

Is there any plans of providing I2C over DMA.
If so when we can get new version of I2C with DMA.

It's a hardware issue: the I2C peripheral on the ESP32 doesn't support DMA.
