18F4520 PWM1CON ECCP dead band delay

[sunay]

Hello,

I've tried to design a microcontroller based half-bridge Mosfet circuit. I 'm using PIC18F4520 that has ECCP module on CCP1. I managed to create PWM signal with this CCP1 module on P1A and out of phase on P1B. Now I just want to make a delay between these PWM signals. I read this site's topics which includes PWM1CON and dead band delay. I used the code as below.

PWM1CON, is _not_ at address 0x9B.
That looks like the address for a 16 chip, rather than a 18 chip.

Safest, use:

#byte PWM1CON=getenv("SFR:PWM1CON")

which will automatically put the right address in for you, to avoid this. PWM1CON on your chip is at 0xFB7.....

Best Wishes

you are absolutely right. I already missed PWM1CON address...

your correction has solved my problem.
#byte PWM1CON=getenv("SFR:PWM1CON")

Thanks for your quick help.


with kind regards,

Sunay
