+====== Debugging with SWO ======
+It is possible to send debug messages through the ARM debuggers trace functionality ITM.
+  * Short solderbridge SB10 on the development board
+  * Put code in the firmware that sends messages
+  * Start debugging, but pause
+  * Enable ITM window and (at least channel 0)
+  * *Press start trace*
+  * Then continue debugging as usual.
