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 am using MPLAB-X (v1.4) and CCS 4.13.

When I try to program the device (dsPIC30F6012a), I always get the following error:
Address: f80004 Expected Value: 8000 Received Value: 8700

I have trac ...

I am starting a project that requires looking at the (precise) amplitude of spectral components in a signal. I stuck a dsPIC on the board because it has a 12 bit ADC and a lot of architectural suppor ...

So instead of battling with the CCS CDC implementation and figuring out where the problem is, I converted my code to use USB Bulk transfers and rewrote the PC software to use the microchip DLL. It wo ...

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.

I have exactly the same problem, please look at my thread just a few posts before yours. Maybe we can compare notes and get to the bottom of this, I suspect it is a buffer problem somewhere with CDC. ...

I have been having this problem for a while and it has been driving me crazy, after a while the PIC will hang when sending out data over USB and CDC. It occurs after maybe an hour of sending/receivin ...

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?

I recently converted a PIC18F4455 project to use a bootloader. After playing with the Microchip USB Bootloader and tweaking my code I finally got it working.

However, I noticed a new problem this ...

Anyone?

I am having some problems with an HID Device that I have created. I have been battling this for a few months now, trying nearly everything that I can think of.

It works fine in Windows. However ...

I am trying to get an HID device working on x64. It works fine on x32 and 98-XP. Last time I checked, it also didn't work with MacOS X. Do you have any suggestions?! The code is just a slight modi ...

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 ...

What you are trying to do is create a digital PLL. You want to lock onto an incoming waveform and then modify the duty cycle. I can see a lot of potential problems with this. Particularly, you don' ...
