Serial selection
On the XMC boards, two kinds of serial outputs are possible, namely:
SERIAL DEBUG (via PC)SERIAL ONBOARD
If these two outputs share the same instance of the internal USIC channel, only one of the two could be used at a given time. The selection can be made via the Tools menu as shown in the picture below.
This is generally the case for most of the XMC boards. However, for boards such as the XMC4200 Platform2Go and the XMC4700 Relax Kit, both the serial output modes are simultaneously active and neednot be selected or enabled from the menu.
Note: Please note that the sketch must be recompiled when a different serial output is selected.
The build flag -DSERIAL_HOSTPC must be used for the serial output interface via PC and the build flag -DSERIAL_ONBOARD must be used for serial output through the onboard TX and RX pins.
