Measure Irms PIC - problem with starting a routine

[BrandonUSA]

Hey guys, I've got a project to do, but I am a bit lost as to where to start, so here is the problem, I want to write a routine in C, that will read the current off of a shunt resistor, calculate the RMS, and send it out via PWM to be read elsewhere, how do I start a routine like that ? Any help is very much appreciated !

Measure Irms PIC

Dear Brandon

Can i have the Shunt Resistor details so that the maximum amplitude of the DC Current can be measured through the ADC Channel..

If so do this your coding


unsigned int ReadADC(unsigned int channel)
{
unsigned char Delay;

ADCHS = channel;
ADCON1bits.SAMP = 1;

for(Delay = 0; Delay < 5; Delay++);
IFS0bits.ADIF = 0;
ADCON1bits.SAMP = 0;
while(!IFS0bits.ADIF);
return(ADCBUF0);
}

The above coding can be used for reading the ADC Channel where u feed the Input signal to measure actually.
