Ok still working on the same pic.
I finally got the oscillation going.
I wrote this program: (I have two questions)
1) why does the DEFINE OSC 20 not work in this case
2) In the program i wrote, NOTHING appears on the LCD
Can I put all the ldout pin on the B port ?
Pin 11 LCD on to PIN 25
Pin 12 --> Pin 26
Pin 13 --> Pin 27
Pin 14 --> Pin 28
anything software for the lcd that i dont have to do with the Pic 16f88 ?
