Splitting C files through Arduino for ESP8266 ?
Posted: Sun Dec 08, 2019 10:12 amHi.
I'm trying to build up a pseudo-framework for my esp8266 projects. The idea is to have the code that my devices share abstracted from the particulars of that device. Functional programming oriented.
i.e. multiWifi setup, MQTT, mDNS, power managment, etc.
I've already coded in plain C the basic structure but after compiling and uploading successfully, the esp goes crazy, never fully booting and in a strange loop.
Any recommendations on how to organise the code? Or something specially wrong with these files.
Thanks in advance.
Here are the files so far:
a_definitions.ino
b_functions.ino
z_base.ino
