Node Server that compile Arduino Code

Setup

1. Install Docker

2. Build the container

sh build.sh

3. Run the container

sh run-dev.sh

OR in production

sh run.sh

Maintenance

Once a month I check the logs on the server.

The log files are located here:

/home/nodejs/.pm2/logs
~/.pm2/logs

To solve disk size problems use this command.

ncdu /

Adding a library

1. Add the arduino library to the arduino-lib.tar.gz file

2. Add the library to the Makefile_uno under the key "ARDUINO_LIBS".

Usage

So the end point is /upload-code/:board. Right now it takes in raw code as the post body to compile. Right now we only compile for the arduino uno board.

curl -X POST \
  http://localhost:9000/upload-code/uno \
  -H 'cache-control: no-cache' \
  -H 'postman-token: 907610fc-5665-71cb-ff6e-687ea34831a5' \
  -d 'void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);                       // wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);                       // wait for a second
}'

If you want to include libraries for the Arduino you have to put them in the sketchbook -> libraries folder. You will also have to do sudo apt-get install arduino-mk to get the package that actually builds the arduino code.
