hi, i was wondering if i could get abit of advice.
Using an example from a book i've been working through, i have built a breadbord for using a pic 16f84a to control the old hitachi lcd controller (in 8 bit mode) , but the project i have in mind requires more i/o so i'm basically just trying to adapt the same code and circuit for the 28 pin 16f876a.
So far i have simply replaced the pic, pulled all the unused pins to +5 through 10k resistors and set them as outputs in picBasic, and just changed the complie options, but it isn't working with the 28 pin.
I've just read on the data sheet that the 16f876a runs from a 20MHz oscillator, where the example project on the uses a 4/mhz rytal, can the 28 pin device also run on 4/mHz? or will i have to change the clock and adjust the delay signals etc for it to communicate with the lcd?
any advice or where to get the answers would be greatly appreciated.
thanks for looking
