As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@
@@
- void
+ int
main(...) {
...
- return;
+ return 0;
...
}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

.. _microbit_display: BBC micro:bit display ##################### Overview ******** A simple example that demonstrates how to use the 5x5 LED matrix display on the BBC micro:bit board. Building ******** This project outputs various things on the BBC micro:bit display. It can be built as follows: .. zephyr-app-commands:: :zephyr-app: samples/boards/bbc_microbit/display :board: bbc_microbit :goals: build :compact: Sample Output ============= The sample app displays a countdown of the characters 9-0, iterates through all pixels one-by-one, displays a smiley face, some animations, and finally the text "Hello Zephyr!" by scrolling.
