Set the command and data times up higher, still the same. LCD is on port B Code:. LCD showing mostly jibberish on 16F I put a 4 line lcd on and the same problem occurs. I went with the best thing I could come up with and assumed that as I can see text at times, then the pic is oscillating.

LCD showing mostly jibberish on 16F Hi, Actually, according to the product selector on Microchips website only 18 out of around models which are in production is missing an internal oscillator of one type or another.
I will add a crystal osc tomorrow and change the osc source and see how I go. I made the pcb with a cnc machine, the socket is very close to the pic and the lcd is plugged straight into it. With both OSC pins floating you have neither. Having said that, in my circuit the OSC pins are left floating. Reading a Hex value from a Modem and showing it as Decimal. I went with the best thing I could come up with and assumed that as I can see text at times, then the pic is oscillating.
Sorry for the confusion. The leg has solder, and the pad has solder, but not convinced they are soldered together. Similar Threads Microcode studio not showing data, though it is receiving it By Tina10 in forum Schematics. Not real happy with a couple of the SMD solder pads for the pic. Both have internal oscillators to 8mhz.
Join Date Jan Posts Thought that all pics had that?? I put a 4 line lcd on and the same problem occurs. LCD showing mostly jibberish on 16F Thanks for thereply. Showing numbers in diffrent ways? LCD showing mostly jibberish on 16F After reading more datasheet and looking at the PBP inc file for this chip, the best I came up with in my dwtasheet state is to change my first line to If the actual speed is different, then all timings will be off. LCD showing mostly jibberish on 16F Your open pins were probably acting like little antennas and picking up datwsheet nearby on occasion that just happened to be what the pic was expecting as an OSC frequency, hence the occasional flicker of life.
Have a look at my last post in this thread http: Members who have read this thread: When I tried your code it compiled OK, but you have one datadheet missing which could be the cause Code:. I added it anyway and no change. How is it doing anything? Floating pins on PICs can do some pretty weird stuff, or on logic chips of any sort. TOP Related Posts.
