I am running into issues even with the 20*4 LCD with too much Msg's Last project (ADC checker) is working upto 3 Rows. Error msg is RP bit should be set manually for indirect addressing or something. I will post about it later. I have read all these issues will be cleared if I use 18F series PIC's I like to know what no's should I keep in stock. There are few here who knows about the 18F part no.s that are needed to keep in hand for projects as such. I am not yet familiar with those yet. So a suggestion about PIC18F no's that I can keep in stock will be a lot of help and I can look up the data to study them. 8 pins to 40 pins will be suitable.
