ESP8266 SPI boot error (yes the correct SPI pins are being used)

Solved: LoRa DIO0 is pulled low by LoRa at startup hence setting the ESP in programming mode. if connected to ESP DIO 0 or 2. Hence the only way to...

SLEEP_MODE_EXT_STANDBY not declared on ATMega168

SLEEP_MODE_EXT_STANDBY not declared on ATMega168

I am sorry!! I am new to this, I have to learn how to use Github. One additional thing I have to mention is that this relates to Atmega 168P,...
