## Compile, Flash & Debug

requirements:
- for compiling: arm-none-eabi-toolchain, gnu-make, git
- for flashing: SEGGER J-Link, JLinkGDBServer (other Debug Probes can be used, see Makefile)

run gdb-server<br />
`./gdb.sh`

build and flash firmware with static DMX-Address<br />
`make program DMX_ADDRESS=99`

build and flash firmware with address selector on EXP1<br />
`make program`

open serial RTT prints:<br />
`telnet localhost 9000`

open cgdb debugger:<br />
`./debug.sh`
