Connecting esp32 RMII to another MCU's RMII
Is it possible to connect esp32 ethernet RMII to another MCU's ethernet RMII without having to put a PHY chip in between? We are using SPI as an interface between a PIC32 and the ESP32, but looking forward we might want to take advantage of ethernet's faster speeds. Both of the MCUs have RMII interf...

I2S_read missing bytes from external ADC
Hi all, I am trying to interface the ESP32 DevkitC to an ADC (ADS127L01) that is currently running on another custom PCB board. I have the required signals of SCK (clock), WS (word select), and SD (data) for the I2S interface jumped over from the ADC to the esp32. The esp32 is a slave and is only re...

Store I2S bytes in different order
Hi, I am using I2S to retrieve data from an ADC. Each sample is 32 bits and comes MSB first with the frame sync frequency equaling the ADC sampling speed. The two most significant bytes come in as the frame sync signal is high and then the two least significant bytes come in as frame sync is low. Th...
