Arduino Firmware

  • Firmware sources are in the "src" folder.
  • Compilated binaries for the differents arduino boards are in the "binaries" folder

If you just want to upload the firmware, go to the binaries folder and follows the intructions given in the README file. If you want to modify the firmware sources, go to the src folder and follows the instructions given in the README file.

Command List

Principle

Basically, a command contains two fields, an integer which represents the kind of command, and a string containing all the required aguments. The end of the command is given by the char ";"

Abstract

Command id Parameters Return Example
Set pin Mode 4 pin mode nothing 4 13 out;
Digital write 5 pin value nothing 5 13 high;
Digital read 6 pin 6 pin value 6 13; => 6 13 1
Analog Read 7 pin 7 pin value 7 2; => 7 2 456.00
Pwm Write 8 pin value nothing 8 3 102;
RCswitch write 9 pin code nothing 9 11 FFFFF0FFFF0F;
DHt11 Read 10 pin 10 pin humidity temperature 10 3; => 10 3 68.00 22.00

Set pin mode

Configures the specified pin to behave either as an input or an output.

  • id : 4
  • parameters : pin mode
    • pin : the pin number
    • mode : in / input / out / output
  • return : nothing

example : Set the pin 13 in output mode

4 13 out;

Digital write

Write a HIGH or a LOW value to a digital pin.

  • id : 5
  • parameters : pin value
    • pin : the pin number
    • value : low / 0 / high / 1
  • return : nothing

example : Write HIGH on the pin 13

5 13 high;

Digital read

Read a HIGH or a LOW value from a digital pin.

  • id : 6
  • parameters : pin
    • pin : the pin number
  • return : 6 pin value

example : Read a high value on pin 13

6 13; =>  6 13 1

Analog read

Read an analog value from an analog pin. The returned value is a float with a two digit precision (we use a 100 oversampling factor)

  • id : 7
  • parameters : pin
    • pin : the pin number
  • return : 7 pin value

example : Read an analog value on pin 2

7 2; =>  7 2 456.00

Pwm write

Writes an analog value (PWM wave) to a pin

  • id : 8
  • parameters : pin value
    • pin : the pin number
    • value : the value to write (from 0 to 255)
  • return : nothing

example : Write a 102 on pin 3

8 3 102;

RCswitch write

Writes an tri-state code on a pin according to the rcswitch library

  • id : 9
  • parameters : pin code
    • pin : the pin number
    • code : tri-state code
  • return : nothing

example : Write a FFFFF0FFFF0F on pin 11

9 11 FFFFF0FFFF0F;

Dht11 read

Read a value on a dht11 sensor

  • id : 10
  • parameters : pin
    • pin : the pin number
  • return : 10 pin humidity temperature

example : Write a 102 on pin 3

10 3; => 10 3 68.00 22.00

Arduino Libraries

The openplacos firmware for arduino use the following libraries

The libraries are packaged with the sources, you don't need to install them.
