LCD showing mostly jibberish on 16F I have used both the pic16f and which are in the list. I added it anyway and no change.
Having said that, in my circuit the OSC pins are left floating. Showing numbers in diffrent ways? LCD showing mostly jibberish on 16F Thanks for thereply.
LCD is on port B Code:. Glad you got it sorted! LCD showing mostly jibberish on 16F Your open pins were probably acting like little antennas and picking up something nearby on occasion that just happened to be what the pic was expecting as an OSC frequency, hence the occasional flicker of life.
LCD showing mostly jibberish on 16F All is good. Just trying to get an LCD to work first on my 16F So, I think it’s either a slow controller or a hardware problem like one of the datalines not reaching the controller. With both Dahasheet pins floating you have neither. Members who have read datasheeet thread: I think you’re right Henrik, I’ve been trying to make it do something it isn’t meant to do. LCD showing mostly jibberish on 16F I must admit I’m surprised that it doesn’t have a built in oscillator.
I’m just glad I’m able to shift some of the blame from myself to Microchip in this instance. Have a look at my last post in this thread http: Floating pins on PICs datzsheet do some pretty weird stuff, or on logic chips of datashheet sort.

I feel stupid for claiming I’ve done this before but not knowing how to set option reg bits. I will add a crystal osc tomorrow and change the osc source and see how I go.

The time now is Both have internal oscillators to 8mhz. LCD showing mostly jibberish on 16F Obviously by using the internal oscillator you can omit the external crystal shown in the easyPIC5 diagram. I haven’t used this pic before so might have some config wrong. LCD showing mostly jibberish on 16F I dayasheet my teeth on the 16F and it is my understanding it does not have an internal oscillator. I am using the internal oscillator, could that be a cause? 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.

Set the command and data times up higher, still the same. LCD showing mostly jibberish on 16F Henrik, That would explain why I can’t find an easy way of turning it on and off. Thought that all pics had that?? It seems unclear 16f7116 me in the datasheet what frequency the internal OSC runs at and if any external components are required.

I’m surprised it worked at all with no datashdet osc components. 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.
When I tried your code it compiled OK, but you have one line missing which could datashheet the cause Code:. LCD showing mostly jibberish on 16F That’s just weird, selecting No and None in the Internal Oscillator column of the product selector produced the datasueet list. Tomorrow I’ll resolder at the workshop and cross my fingers. Join Date Oct Posts I don’t think it’s a connection problem but I will triple check.
I put a 4 line lcd on and the same problem occurs. I have replaced the pic already and suspect I didn’t get enough heat onto the pad 2nd time round.
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’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? I made the pcb with a cnc machine, the socket is satasheet 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. I’d add a note to the post with the list but unfortunately I’m not trusted to edit my own posts.
The leg has solder, and the pad has solder, but not convinced they are soldered together. The list is flawed and so is the data Microchip is using in their selector tool – which is what 16f71 the list.
LCD showing mostly jibberish on 16F That seems correct. I’ve never used that line before and always used 4-bit LCDs.
