Serial Interface on pic18f2550
Hellow,

After quit a few attempts to read from the serial port of my pic18f2550 I've come to the conclusions that no matter what baud rate I use, my timings are always off.

As a result everything I sent or recieve trough the serial port is gibberish.
I was wondering what would cause this.

I must admit that my pinguino's are based on the setup of an xbox nand reader. You can find more about this reader over here: http://dev360.wikia.com/wiki/USB_Nand_SPI_Flasher

Now there are 3 major differences in my setup:
- I've used a crystal 12mhz! I've adapted the bootloader in winpic but I don't know if that's enough...
- I've setup Low Power so it was possible to program the pic with an art2003. This is also done in the nand reader of the xbox. I believe this was done by pulling down pin 26...
- I've used 33pf caps instead of 22pf caps.

I've also changed my PIC with another one to see if this worked but with little success. Also I'm trying to read/write to tx and rx with a raspberry pi.
Could this be a problem?

Before I order new parts or do something I could really use a professional opinion.

Ps: I think this issue is related to another post of my where I couldn't get a bluetooth device running. Now I realize it's not the bluetooth device that's causing the problems: http://forum.pinguino.cc/showthread.php?tid=4290

Regards
