IoT - Collabs - ESP Firmware with Guru

Modular Firmware

Baseline

This is the basis for pretty much ANY ESP-based firmware project. It'll get your device online.

main.cpp

 1 #include "TopSecret.h"
 2 #include "functions.h"
 3 
 4 void setup()
 5 {
 6   Serial.begin(115200);
 7   delay(50); // Delay to let the ESP get booted before sending out serial data
 8   Serial.printf("\n+---------------------------------------+\n");
 9   Serial.printf("|             ESP Baseline              |\n");
10   Serial.printf("+---------------------------------------+\n");
11 
12   setup_wifi();
13 
14   // Turn off the On-board LED (notice that it's inverted on most ESP boards)
15   pinMode(LED_BUILTIN, OUTPUT);
16   digitalWrite(LED_BUILTIN, HIGH);
17 }
18 
19 void loop()
20 {
21   // put your main code here, to run repeatedly:
22 }

The parts

Work Environment (Platformio/VSC setup)

Declarations and Defines

Individual Functions

MQTT

This is intended to be added to the baseline.

You'll need to add:

lib_deps =
       PubSubClient

to your platformio.ini file.

main.cpp

Add:

setup_mqtt();

to setup() after the setup_wifi(); call.

Put:

DOtheBloodyMQTT();

inside loop()

NeoPixels

Extreme WIP

This is intended to be added to the baseline.

You'll need to add:

lib_deps =
       Adafruit NeoPixel

to your platformio.ini file.

and put

#include <Adafruit_NeoPixel.h>

in your source

Multitasking

Multitasking requires non-blocking code. It also requires a way to call functions without waiting for other functions to start & stop things.

Jean-Francois Turcots SimpleTimer Library makes this fairly straightforward.

Add SimpleTimer to the lib_deps in yout platformio.ini file.
