[PIC] p18f1330 not working with my code, help needed

[ruben91]

hi, currently i'm working on a new pic, p18f1330. bt previously i was using p18f4580 and my coding works fine, but wen i convert it to port in p18f1330, its not working, pls help..my project is using ultrasonic hc-sr04 sensor. whereby the distance measured will be display in hyperterminal and LED wil blink at diferent rates.. now i port it to p18f1330, wit jus led blinking and nt dispalying in hyperterminal, but now its not fuctioning, please help

i'm using mplab ide, c18 compiler and pickit2

I noticed in your code for p18f1330 that you use time=TMR0H and not TMR1. Maybe this is the problem.
