ESP32 + ESP-IDF + MCP2515 How to?
Posted: Mon Jan 21, 2019 12:28 pm
Hi!
I am trying to connect MCP2515 to ESP32 using esp-idf, but can do this.
MCP2515 have SPI interface, but examples from IDF documentation use RX and TX.
But where to connect SCK and CS pins?
I tried to use it without these pins, but can send or receive any messages.
What is the proper way of connecting and initializing MCP2515 with ESP32 and IDF framework?
