You're all right, but it's got to be something else... The PIC appears to be ignoring the RS232, even though the data is being sent.

At the end of my code, I added:
while (1) {
...

I can't seem to get that to work either... hmm, I'll have to try a few other things to confirm that my hardware still works. :-p

Hm, I'm trying to capture the data so I can check it. The get_string command only sends it back out, so that's not too useful here.

I've got a small problem with some code I'm writing. I've got all the rest of the function correct, but this code is getting stuck in the loop and never finishing.

int check_pw(void) { ...

Hm, I was planning on using the hardware UART for both signals just to avoid setting up the software UART and interrupts. All I really want to do is ignore the incoming data on one line and allow the ...

Since I've had so much luck on the first help I got here, I figured I'd try again.
I've been searching the forums and I've found a few solutions for driving 2 signals on a single USART, but nothing t ...

Wow! That's some fairly dense code.
Thank you very much for all of your patient help. I'm implementing this on a PIC16F877, so I probably can use the hardware USART and hack down some of that code. I ...

As mentioned previously, the basics for this can be found in the bootloader

Now we're getting into more specific code.
The bootloader examples gather the "program" from the RS232 in hex (according ...

The program memory can be read and written as easily as the EEPROM and there is more than enough memory space on PICs to accommodate your data set as described.

I'm not quite sure I understand... s ...

How large is 'large'?...

There should only be 5 or so "sets" of data. The tags only come in 8-byte segments, which I've determined I need to compare byte-by-byte to an incoming serial buffer. The n ...

Hello,
I'm still VERY new to PIC programming, and I want to tackle what seems to be a very challenging topic: storing of a table of information in memory.

Right now, I have a list of five or six 8 ...
