We have a ESP8266 and and Arduino Mega connected through SPI, where the ESP is master, and the Mega as slave. The ESP uses this communication channel to retrieve values of sensors connected to the Mega. I am wondering what frequency to set on the ESP for the SPI clock. Is there a way to calculate …
