ESP32 Forum

Hello Support,

We intend to use ESP32WROOM32UE in our project interfacing it with microcontroller & use it as Network Co-processor. I can't get any relevant document about how to interface ESP32WROOM32UE with microcontroller & which suitable peripheral to be used like SPI/ UART/ I2C. I know SDIO is acquired by internal flash so that option might not be available.

Please advise we are stuck with design.

Regards,
jagdish

Hi,

You can take a look at this https://github.com/espressif/esp-hosted.
The ESP32 can be used as peripheral using a host MCU.
