Period calculation with PIC18 using C18

lakis said:

Hi guys ,
i take Wond3rboy code and i am trying to measures the period and the high time of rectangular waveform using capture mode and display them on a 2x16 lcd . I am using ccp1 as input .
But although the program is build succeeded the screen doesn’t display anything .

I am working with pic18f452 and pic18f4520 I use mplap ide v8.63 and c18 lite v3,36.
The period of the waveform can be adjusted between 1,5ms and 3ms and it is between 3 and 5 volts .
This is the code I’m working on .



i think i have added all the source file that the c18 functions need to work.(cp1close,cp1open, cp1read,t1open,t1write) and for lcd ( wcmdxlcd,putsxlcd,openxlcd,busyxlcd)



please help me .

Thank you.
