still no luck. I don't have time to continue so I will j ...

Two things: 1. I copied the code from hugo's flex driver from this thread and he said it works with 1,2,3, and 4 line displays, and 2. he said it worked.

The first driver posted it was mentioned di ...

So This is my attempt to modify the driver for a two-line display. It still doesn't work:

I am not sure what you are referring to but all grounds are common. If you are refering to the debugger, the ground is common, if it was not I would not be able to program the PIC, if you are refering ...

There is only one clock and pone data line for i2c from my pic they are the pins that are used in the code and the logic analyser shows data on them (whether or not it is correct data is another matte ...

Here is my LCD:

I have really given up on the ICD printf thing, back to the LCD problem, would it help if I posted my wave-forms? If anyone is familiar with i2C and/or this LCD maybe they can tell me if these wavefor ...

I have spent all day working on this and going through forums, from what I can tell my processor doesn't have a B3 pin but that is ok because you should be able to use any pin. This is the code I used ...

How do I use the printf? Like I said I never used PIC before and I don't even know what pin to use to get printf to work. Here is the programmer I am using:

hmmm, the chip on my i2c module says (in the tinyest of print) pca8674, so thinking maybe slightly different code might be needed? Also I think the pins to the LCD are different then what is in the co ...

I do have the 5V, 3V, and both ground connections. I just gave up and replaced the board with a homemade level translator using 2 2N2222A NPN transistors and 4 5.1K pull up resistors. Basically, I mad ...

I rebuilt just the LCD portion of the system on a breadboard with a spare pic and level translator, and I have come to the conclusion that the level translator is the problem. I tried the following co ...

So I changed to 0x40. I was getting some data but I also noticed that I was getting only 1.5V max on both Input and Output of level translator. I then realized I never grounded my logic analyzer. If I ...

I am using the icd-u64 with 3 pins, clock, data, and mclr connected. My project is a sun following solar powered cell phone charger with internal battery. I want to implement data logging of the charg ...

I can't do anything with printf, I don't think I have enough pins left to use a serial connection. In any case, I think the issue might be the level translator and/or LCD. I removed the translator and ...
