# 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
[...]
```
