BBIO-Server Development - 2

| Comments

Currently we have developed the basic RESTful API for the BBIO-Server. The functionality currently supported includes : GPIO, PWM, analog in, Servo and custom modules.

GPIO handler : 
  GET /gpio/1/16?task=write&state=HIGH    :: sets pin GPIO1_16 high
  GET /gpio/1/16?task=config&mode=INPUT   :: sets pin to input mode
  GET     /gpio/1/16?task=read                :: reads pin, returns status

PWM handler :
  pwm to work with default configuration.
  i.e. freq = 10KHz and resolution = 8 bit

  pin to pwm mapping :-
  P8.13 - PWM2B
  P8.19 - PWM2A
  P9.14 - PWM1A
  P9.16 - PWM1B

  GET /pwm/1A?value=10
  
Analog In : 
  function to handle ADC read requests. 
  Input can be from 0 - 1.8V, o/p of 12 bit resolution

  P9.33 - AIN4
  P9.35 - AIN6
  P9.36 - AIN5
  P9.37 - AIN2
  P9.38 - AIN3
  P9.39 - AIN0

  GET /adc/AIN0 => returns the analog input at channel 0
  
Servo controller :
  each servo is attached to a PWM module

  GET /servo/PWM1A?config=enable  => enables this module
  GET /servo/PWM1A?angle=50   => moves servo to 50 deg
  GET /servo/PWM1A?config=disable => disables this module

Here is the code that has been currently written :
