= Real-Time-Clock (RTC) Example
This example illustrates how to use a Real Time Clock (RTC). To measure longer
times it is recommended to make use of the RTC. If the RTC is initialized the
standard C date and time functions can be used.
[NOTE]
Epoche-converts are available to get the Unix timestamp to configure the RTC,
see https://www.epochconverter.com/[https://www.epochconverter.com/].

== Makefile Usage
[source%nowrap, bash]
----
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
----
= Manual
== Building
[source%nowrap, bash]
----
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
executable (bin, elf, hex ...).
== Flashing
[source%nowrap, bash]
----
$ 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) Build the application with debug symbols enabled by adding `--profile mbed-os/tools/profiles/debug.json`.
[source%nowrap, bash]
----
mbed compile -c -m XMC_4500_RELAX_KIT -t GCC_ARM -N main --profile mbed-os/tools/profiles/debug.json
----
(2) Start the `JLinkGDEBServer`, e.g.:
[source%nowrap, bash]
----
JLinkGDBServer -Device XMC4500-1024 -if SWD
----
(3) In order to log messages printed to `stdout` we connect to port 2333 via
telnet.
[source%nowrap, bash]
----
telnet 127.0.0.1 2333
----
(4) We launch the debugger and control the debug session:
[source%nowrap, bash]
----
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
