+# InterruptIn Example
+
+This example illustrates how to facilitate an interrupt using an IO asd input
+with the XMC4500 Relax Kit. In particular, port P1_15 connected to BUTTON2 is
+used as interrupt source. Whenever a rising edge is detected LED2 will be
+switched on, otherwise, when a falling edge is detected LED2 will be switched
+off. In other words, when you press BUTTON2 LED2 will be on when you release the
+button, LED2 will be off.
+
+![alt-text](seriallog.png)
+
+This example also uses MBED-OS queue functionality as well as UART1 on the XMC 
+Relax-Kit.
+
+## Makefile Usage
+
+```
+make          # build the application
+make flash    # flash the application
+make debug    # debug the application
+make erase    # erase the program memory
+make doc      # invoke doxygen
+make clean    # clean the project
+```
+
+# Manuell 
+
+## Building
+
+```
+mbed compile -c -m XMC_4500_RELAX_KIT -t GCC_ARM -N main
+```
+
+This creates several files in the BUILD directory where you can find the
+executables (bin, elf, hex ...).
+
+## Flashing
+
+```
+$ JLinkExe -Device XMC4500-1024 -if SWD -speed 4000
+J-LINK> h
+J-Link> loadfile BUILD/XMC_4500_RELAX_KIT/GCC_ARM/main.hex
+J-Link> r
+J-Link> g
+```
+
+## Debugging
+
+(1) Start the `JLinkGDEBServer`, e.g.:
+
+```
+JLinkGDBServer -Device XMC4500-1024 -if SWD
+```
+(2) In order to log messages printed to `stdout` we connect to port 2333 via
+telnet.
+
+```
+telnet 127.0.0.1 2333
+```
+
+(3) We launch the debugger and control the debug session:
+
+```
+arm-none-eabi-gdb -q BUILD/XMC_4500_RELAX_KIT/GCC_ARM/main.elf
+(gdb) target remote :2331
+(gdb) monitor reset
+(gdb) load
+(gdb) monitor reset
+(gdb) b main
+(gdb) c
+[...]
+```
