Using Peripheral Uart via JP1

[Anonymous]

Like many others I would like to use the peripheral UART to communicate with another processor. Currently I want to find the easiest way to get the UART lines off the TAG EVAL board without soldering if possible. The schematic seems to indicate that JP1 has access to UART lines but looking at some of the posts I gather that its not that straightforward. Does anyone have any suggestions with trying to read the peripheral UART lines out of JP1 ?

Peripheral uart is not connected to JP1 on the tag board. Most sample applications configure P32 and P33 as the puart lines, so you have to solder wires or a connector to TP55 and TP56.

The next revision of the tag board will have headers to which you can connect jump wires and it will also use an FTDI 2232 chip so both uarts show up as virtual com ports on your PC.

You mentioned TP55 and TP56. I don't see these in the board layout document. I see P32 and P33 (which is shared with P8). Are these the points you are referring to ?

Thanks a bunch

Yes, P32 and P33.
