I'm having trouble making string functions.

For example:

printf("hello world");

works just fine... But I want to make my own string functions...

void MyStringFunc&# ...

AH HAH!!

I got it... I had read the datasheet for my LCD wrong. I was applying 4.6 volts to the Vo pin. I was supposed to be applying .4 volts. The datasheet says Vdd - Vo = 4.6... I basically h ...

Hi,

Thanks for the help.

I tried like you said and used the regular LCD.C code with only changing the initial delay to 30ms. Same result... nothing.

About the Vo of the LCD. With nothing ...

Hi,

I am using a Lumex LCD with the samsung driver. I have modified the CCS provided driver as follows:

void lcd_send_nibble( BYTE n ) {
lcd.data = n;
delay_cycle ...

Hi,

I have a few general questions about interrupts in PIC microcontrollers. I think I know the answers but I just want to make sure...

1) When I set up my interrupts for change on port B and t ...

Hi,

Thanks for the comments. I realized the count = 2 problem. It was a typo. Smile

Ah... I guess I shouldn't name my functions the same as CCS functions, huh?

Thanks!

I've got a timer setup to interrupt. Then on every third interrupt I want to call my read_adc() function. My code executes, but it doesn't ever appear to actually go into the read_adc() function. N ...

Hi,

Thanks for your help. I've almost got it working now. I can write to and read from my ADC. However, my ADC is not responding yet.

I've tried both SPI_L_TO_H and SPI_H_TO_L. Looking at th ...

Hi,

My ADC has its chip select tied low (active low).

I realized that I had my oscilloscope hooked up to the wrong signal. The ADC still isn't working yet, but now I have a better idea of what ...

Hi,

I'm trying to set up an SPI port to communicate with an ADC. It doesn't appear to be working.

I am putting an oscillscope on the DO pin from the microcontroller and I am seeing a digital ...

Thanks for the help. I have been using it with the "powered from ICD 2" option. I have a Vdd of 4.82 volts.

Here is what the status window says:

Connecting to MPLAB ICD 2

I'm not using a prototyping board... just a breadboard.

I've bot the VSS and VDD from the ICD 2 going to the chip (both VDD and VSS inputs). I've got a 4 MHz crystal oscillator connected to OSC1 a ...

Ok.. I have my new PIC18F4620, ICD 2, CCS compiler...

I'm powering the chip from the ICD 2 programmer. I'm running the following code:

#include <18F4620.h>
#fuses HS,NOWDT,NOPROTECT,NO ...

DOH! I knew that!

Thank!

From what I've read, you can have either a HW i2c or a SW i2c...

Can you have multiple i2c connections to other hardware with one PIC?

My application requires me to connect to an LCD display, AD ...
