Library for Heltec ESP32 Dev-Boards by Heltec Automation
I have a Heltec ESP32 V2,
from a version 2.0.1 and above, Arduino IDE reports an error:
... libraries\Heltec_ESP32_Dev-Boards\src\driver\sx1276.c:1289:5: error: implicit declaration of function 'SpiInOut'; did you mean 'SpiInit'? [-Wimplicit-function-declaration]
