Hello Robert,
I get the impression there is a lot more to your problem(s) that what you have described (two UART's requirement, modification of printed circuit boards (PCB's) before they are received, two different processor, etc.) but this oscillator thing can be difficult especially if they don't start to oscillate upon power up. Here is a good reference source I have found helpful. http://www.ee.washington.edu/circuit_a...ISCHEM_009 Crystal Oscillator (From Goran Olsson) (Updated April 16, 1994). Regards, Charles Bannister Thanks for the link. Very interesting. Not sure what you mean by a lot more to my problem? Everything is / was looking good before I started using the TI UART vs the Philips. Cheers, Rob. |
