implement a software for PIC12F629 microcontroler

Hi,

Target is provide a project for last mplab ide and that implements in C language for a pic 12f629 microcontroler the following specifications

A hex compiled firmware should be provideed in order that I can uploaded for testing

Generate PWM carrier on a gpio with pulse length according of a message array content

See picture in attachement

Pic should be configured to run at 4Mhz with internal oscillator

Code to implement :

- 12F629 generate a 56khz pwm carrier using one timer

- Start/stop based the pwm carrier based on the content of a message array 

- Message array length is 10 bytes 

- At the end of the message PWM is stopped

For exemple for if message array content is [1,0,0,1,1....]GPIO : PWM for 139usGPIO : 0 139usGPIO : 0 139usGPIO : PWM for 139us

GPIO : PWM for 139us

....

So interup timer should be called every 139uS 

sendMessage function will never be called before a message is fully sent, interupt timer doesn't need to be disable when not message has to be send, when a new message has to be send it will be processed when next interrupt timer function occurs

enablePWM  function -> enable 56khzpwm on GPIOX (X mean that you choose the gpio)

disablePWM function -> disable the  PWM

PWM ration 1/2

======================================================Pseudo code:#define MESSAGE_LENGTH 10

global char Message[MESSAGE_LENGTH];global char sendPosition =  MESSAGE_LENGTH;

//  generate 56khz pwm on gpioX (X mean that you choose the gpio) enablePWM() {

 }

//  disable pwm on gpioX  (X is same value as for enable) disablePWM() { } 

  /* enable/disable PWM output bassed on message content coding */  

interupt timer {

  if(sentPosition <MESSAGE_LENGTH) {     if(Message[sentPosition ] != 0 ){       enablePWM();

     }  else {         disablePWM();

     }     sendPosition+=1;  } else {     disablePWM();  }}

/* initialise the message to be sent in timer interrupt */sendMessage([char [newMessage]) {

      process array off pulse       sentPosition = 0;      for(i=0;i<MESSAGE_LENGTH ;i++) {        Message[i]  = newMessage [i];

      }}

in main {   char newMessage[MESSAGE_LENGTH ] = { 1,0,0,1,0,1,0,1,0,1}

    while (1) {          startFrame (newMessage);

          sleep around 1 seconde          startFrame (newMessage);

    }     }
