It works !

Thank you very mutch.

No one has ever used the hardware UART on a PIC16F688 ???

If anyone has done it, I would really like to have a code example. I've tried different things in the last three days but nothing worked.

You must understand that you are not mesuring directly the frequency but calculating it from the period (f=1/T). The way you measure the period is by counting how many cycles at 40MHz will be complete ...

I changed my TRISC value for 0xFF since I read on the datasheet that it has to be 1 for both TX and RX. Anyway, it changes absolutely nothing, it still don't work.

In your original post, you said that the "signal for the byte I send is also different from what I expect". Now you are seeing nothing?.
Assuming the original code was sending something, what were y ...

I tried redoing it without using the CCS templates, by directly accessing the registers but it still doesn't work.

If anyone can get a look at the code, I zipped the project at:

void Init(v ...

Are you a simple customer as I am or do you work for CCS ? Because if you are just a user as I am, maybe you are not the one who should have to do that.

Anyway, thanks a lot for your time.

Simo ...

I cut and paste your program, compile it and it still do the same thing. On the other hand, if I try to use another pin (software UART), then it works but I don't know why.

Thank you.

Hi,
1 - I tried to put TX on RC4 and RX on RC5 as described in the datasheet but my scope showed nothing on Pin #6 (RC4): 1.2V constant. Then, I thought that the TX and RX names might be seen from t ...

Hi, I'm new to both PIC and CCS. I have a problem with using the UART transmission working. I use a 20 MHz oscillator, the delay is working fine (verified), the hardware seems OK, I toggled the pin 5V ...
