I made the pcb with a cnc machine, the socket is very close to the pic and the lcd is plugged straight into it. Apart from that it’s the usual suspects like ADC and comparators but your device doesn’t have any of that on the pins used so that can’t be it. And it doesn’t seem to be in your list Henrik.
The leg has datasheer, and the pad has solder, but not convinced they are soldered together. With both OSC pins floating you have neither. LCD showing mostly jibberish on 16F Henrik, That would explain why I can’t find an easy 16f7116 of turning it on and off.

Join Date Dec Posts When I tried your code it compiled OK, but you have one line missing which could be the cause Code:. The issue is that I get mostly jibberish all over the screen changing constantly, with glimpses of the text I’m trying to put there.
Members who have read this thread: I haven’t gone that high with the numbers so I’ll try that in the morning.
I’m surprised it worked at all with no external osc components. Just trying to get an LCD to work first on my 16F Join Date Jan Posts 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 All is good. The time now is I’d add a note to the post with the list but unfortunately I’m not trusted to edit my own posts. Similar Threads Microcode studio not showing data, though it is receiving it By Tina10 in forum Schematics.

LCD is on port B Code:. 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 tired state is to change my first line to Thanks for pointing datashee out Mark!
Set adtasheet command and data times up higher, still the same. LCD showing mostly jibberish on 16F I must admit I’m surprised that it doesn’t have a built in oscillator. If the actual speed is different, then all timings will be off.
I am using the internal oscillator, could that be a cause? Reading a Hex value from a Modem and showing it as Decimal.
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. LCD showing mostly jibberish on 16F I have used both the pic16f and which are in the list. Results 1 to 22 of LCD showing mostly jibberish on 16F That seems correct. Checking the 16F does indeed show it’s got internal oscillator.
LCD showing mostly jibberish on 16F Having said that, in my circuit the OSC pins are left floating. Have a look at my last post in this thread http: I will add a crystal osc tomorrow and change the osc source and see how I go.
I put a 4Mhz osc on it thismorning, works perfectly. Both have internal oscillators to 8mhz. It seems unclear to me in the datazheet what frequency the internal OSC runs at and if any external 16716 are required. I don’t think it’s a connection problem but I will triple check. I added it anyway and no change.
I’m sure I recall using a specific command to use the internal osc in the past, whereas this datasheet indicates clearing option register bit 5 will turn it on? Thought that all pics had that?? LCD showing mostly jibberish on 16F I don’t have a 16F to play with, but the following code works with an 18F running at 4mhz from its internal clock.

Not real happy with a couple of the SMD solder pads for the pic. Glad you got it sorted! Floating pins on PICs can do some pretty weird stuff, or on logic chips of any sort.
