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 ... |

When I try to program the device (dsPIC30F6012a), I always get the following error:

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. ... |

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.
