PostForum: General CCS C Discussion   Posted: Sun Oct 28, 2012 11:06 pm   Subject: HW UART, Disable TX pin?
Is it possible to disable/float the transmit pin of the HW UART?

Essentially, I only want the PIC to listen to the RS232 bus but not be able to affect the current bus transmissions. (Obviously the ...

I do no think it is hardware or power related either. I believe it is a firmware issue with CCS's implementation of the CDC stack.

PostForum: General CCS C Discussion   Posted: Tue Dec 18, 2007 11:05 pm   Subject: USB Bootloader and Reset Problem
So it appears that when it gets into this "state" the oscillator isn't oscillating. I don't do any kind of oscillator switching, just an external resnator at 10MHz.

Any ideas?

However, I noticed a new problem this ...

Just an FYI for those that run into this, if you #define PIC18F2455 before you include any headers, the compiler will crash in module PCH.dll. Might help to have the parser check for this or at least ...
