SPI API Missing Interrupts #1943
Description
Basic Infos
Hardware
Hardware: ESP-12
Core Version: 2.1.0-rc2
Description
The SPI implementation included in the ESP8266 is missing hardware interrupts. The official API lists this function as:
https://www.arduino.cc/en/Reference/SPIusingInterrupt
Without this, one of my libraries is unable to function.
