Hi, I had tried to write program for pulse reading and generate PWM according to input pulse width. AC triac dimmer used. Optocoupler gives square wave input with variable pulse width. I am facing pro ...

got a SCHEMATIC??
and your FULL CODE ??

a faulty zero cross detector can make your whole thing bad -
but ???

I want to control AC phase angle controlling TRIAC gate signal. I am using timer0 interrupt with

setup_timer_0(RTCC_INTERNAL|RTCC_DIV_4);

and check adc value from trimpot.
I am using ...

I am using PIC 16F684 to read pulse from optocoupler that outputs a square wave on INT pin. I am trying to write code with input frequency 100Hz.

I am using PIC 16F887 as master and MY9221 as slave. Communication with MY9221 is 16 bit communication and data is written in MY9221 on both edges of clock cycle. I had tried but get no proper commun ...

Thanks sir for your valuable response. If I want to use 10bit ADC and 10 Bit PWM with 2KHzs freqency how to use program?
I had worked with 250Hzs it gives proper output but frequency changes from 250 ...

I am using PIC 16F684 for light dimming application. Previously I had used 250Hz frequency. My application is to read ADC and generate PWM according to input of ADC, dimming from 420 count (2.0V ADC) ...

Thanks sir my for your valuable reply. My Controller handling 1 Analog input, 1 digital input and 3 digital output and 1 PWM output no other pin free. I think this problem solve by replacing controlle ...

As posted ealiar I have used MCLR pin of 12F615 as digital input. But i face one problem that after sometime these pin reset the device is it possible? I had go through datasheet but my doubt not be c ...

Thanks
for your reply ya i have toggle successfully another PIN but one of pin is MCLR(RESET) pin how can i toggle that pin. I'm new to CCS compiler I have only know about 8051.
