The Arduino programming language is a superset of C++.
C++ is a superset of C.
For some strange reason, the people who developed Arduino decided to eliminate a lot of the constraints of C & C++ that make the code maintainable.
Luckily, you can program in C or C++ using proper techniques & compilers for Arduino will not choke on your code.
main.cpp
1 #include <Arduino.h> // Pretty much only here to giv us Serial Communications & delay()
2
3 #include "FooBar.h" // This header file lives in the src directory
4
5 void setup() {
6 // put your setup code here, to run once:
7 Serial.begin(115200);
8 Serial.println("Howdee!");
9 delay(5000); // What a silly way to rape a microcontroller...
10 }
11
12 void loop() {
13 // put your main code here, to run repeatedly:
14 Function1();
15 delay(1000); // UGH...
16 Function2();
17 delay(1000); // UGH...
18 }
FooBar.h
1 void Function1();
2
3 void Function2();
Function1.cpp
1 #include <Arduino.h>
2
3 void Function1()
4 {
5 Serial.println("Hi Grant!");
6 }
Function2.cpp
1 #include <Arduino.h>
2
3 void Function2()
4 {
5 Serial.println("I'm a microcontroller...");
6 }
platformio.ini
(Coz I have this preference in IDEs...)
