SPI Questions
Posted: Fri Mar 26, 2021 2:20 pm
I need an ESP32 to communicate with an ESP8266 via SPI. I have used the SPISlave code successfully on the ESP8266 so I know I have the proper connections. My question is this: I need the ESP32 to be able to send 200 byte messages to the ESP8266 and I need the ESP8266 to be able to reply with 2000 byte messages. There are comments in the SPISlave code that says there is a 32 byte limit on the data that can be sent and received. Is this true? If so, is there a way around this limitation?
