Works fine for the numbers now, my problem was with my coding.

Now I am wondering how to get the screen to scroll up or down when needed. Can the lcd_gotoxy function be used for this?

Can this driver be used to properly send decimal numbers to the LCD or will we get errors?

Problem solved, it was a hardware problem with the jumper connected to the TX pin... -_-

Hey guys,
I am currently trying to communicate between two PIC's.
I am successfully receiving data and displaying it on an LCD with PIC16F877A. But transmitting data through its TX pin with the use ...

I fixed a few errors that I found in in the code i'm using to transmit data.

void write_buffer(void)
{
char ch_str[20] = "ATZ\r"; // puts character in string ar ...

That was a stupid mistake... But even if I fix it I am getting no life from the TX pin.
I must be missing something simple here..?
Would I possibly have to set the TRIS to have TX as output and RX a ...

Ttelmah that configuration worked like a charm!

I can't thank you guys enough, you guys are great help! Smile

Would anyone be aware if CCS also provides example files to send data through the TX p ...

#if defined(__PCM__)

Thanks for mentioning that. I am communicating between two pics. When my main pic receives this ">" (0x3e) it means that the device is in idle state and no more data will be transmitted. ...

Ok so I just have to figure out how to write this function so that it stops when all the data has been received.
Question is how am I supposed to know when all the data has been received?

EDIT:
...

Yes that makes sense. Thanks. So I'm guessing that there is nothing more to it then that?
As long as there is nothing that I should watch out for that could damage my PIC or give me unwanted errors ...

Hey guys,
I am using the CCS ex_sisr example file as a model to receive serial data through my RX port and display it on an LCD.
My code works fine and the data is displayed as expected on the LCD. ...

Well the MOSFET did the job perfectly. Thanks for the help guys!

If I am not mistaken that is a key matrix.

Maybe this schematic will be clearer:

Hey guys,

I am making a 4 button key matrix for my project. The matrix will be directly connected to 5 pins on the microcontroller. Below is a link to an image of my schematic.
