I'm use the PIC 16f877a

Thanks

Hello All,

I'm a bit desperate right now, could anyone point me to simple C code for sending and receiving rs-232 on a PIC16f877a.

Thanks.

I tried to re-call a function. It told me recursion is not permitted any ideas?

With prototype headers

void start();
void end();
void main();

void start()

I have a PIC16F877A, I want to read the digital input D0-D7 coming in from a separate adc chip. I know I can set the port C of the pic to be an input by:

SET_TRIS_C(0x00);

However, how do I tran ...

I'm trying to interface a 4x4 keyboard matrix to a PIC16F877A, I was wondering does anyone know which pins on this keypad are the row and which are the columns the data sheet is unclear about this.

I changed:

while(1)
{
set_adc_channel(0);
delay_us(20);
voltage=read_adc();
con_voltage2 = voltage * (5.0/1023.0);

When I have a 5V input on my PIC 16F877A ADC AN0 Port is outputs:

1023 on the LCD which I know is the correct value, but when I attempt to multiply by 5/1023 and this does not gives me a result of ...

Thanks, but I got it working.

I modified to the following:

while(1)
{
set_adc_channel(0);
delay_us(20);
voltage=read_adc();

Thanks, Vinnie for your reply, I made the following modifications. The output is just 000000, even when I have plugged the RA0 to 5 V.

I'm new to the world of PIC. I've got my LCD working, but I'm trying to display the voltage I that is read in by the PICs ADC port. I'm using the PIC 16F877A, here is sections of my code. However it k ...
