ESP32 Forum

I am doing a project where I want an dedicated RGB8 interface and intergrated EMAC for ethernet in the MCU. I read the ESP-IDF of esp32s3, it said ''ESP-IDF provides a set of consistent and flexible APIs to support both internal Ethernet MAC (EMAC) controller and external SPI-Ethernet modules.'' https://docs.espressif.com/projects/esp ... p_eth.html. Because the hardware does not support Ethernet. Is it possible to add EMAC by using ESP-IDF? If it works, how fast is the data rate?

ESP32S3 does not have internal EMAC. Therefore you cannot connect Ethernet PHY to it. You have to use SPI Ethernet module which has the EMAC integrated. Or you can switch to ESP32 or ESP32P4 if it satisfies to your needs.

BTW, regarding documentation. I'll fix that introductory section to make it more clear.

Thanks for the explanation and suggestion of other product. I thought about the ESP32 and read the datasheet and technical reference manual. It seems like there is only a dedicated RGB8 input port supported by Camera Slave Receiving Mode. But in my project I also need a dedicated RGB8 output port. Is it also possible for ESP32?

ESP32-P4 seems really fit for my project. Is the product already available? Or when will be available in Germany?

Best regards
