For a school project, I have a dragon12-plus-usb board, that I need to communicate with a zigbee rf transceiver over the sc1 serial port.
But first I need 3.3v power for the zigbee. The 3.3V connector on my drag12 board, I don't see any voltage on my volt meter. Yet, the 5V connector does register on my volt meter.
I can't find any info on which jumper, or whatever I need to do to activate the 3.3V power.
It is driving me crazy, because I am talking to the SC1 port just fine. (When I loop TXD back to RXD I read whatever I send).
Any help would be appreciated. The end of the semester is rapidly approacing.
