Hi everyone,
1. I've setup my Nokia 6100 LCD, read the datasheet and some tutorials by Jim Lynch (Sparkfun) with some improvisations. I built the circuit using just a perfboard, and hopefully got it all right.
The only thing is, the example programs are a bit harder for me to understand, since they use libraries. I only want to test the LCD and see if my setup is working, so I need a code to just light it up. I can, however, write bare C programs without libraries.
So basically, here's how I connected everything:
1. RC5 (SDO) to SDI of the LCD,
2. RC3 (SCK) to SCK of the LCD,
3. RB2 (PORTB) to RESET
4. RB3 (PORTB) to CS
I shifted the voltage output of the PIC using diodes to around 3.9V (The max rating, I believe is 4.0V from what I read in the datasheet)
Also, I used an LM7808 (8V output) to power the lighting.
So, can anyone guide me to a simple, library-free test program? I've fossicked everywhere for it, no avail though.
2. There's also another thing. I tested the output of the PIC's toggling output (to simulate a SCK and SDO signal) at 1ms interval. After the signal goes through two voltage-dropping diodes, the output is like this:

I wonder if it affects the performance of the LCD?
Thanks for the time spent on this guys.
