Title: Disco demo
|
||
|
|
|
||
|
|
Description:
|
||
|
|
|
||
|
|
A simple 'disco' demo. The demo assumes that 2 LEDs are connected to
|
||
|
|
GPIO outputs of the MCU/board. The sample code is configured to work
|
||
|
|
on Nucleo-64 F103RB board, with LEDs connected to PB5 and PB8
|
||
|
|
pins.
|
||
|
|
|
||
|
|
After startup, the program looks up a predefined GPIO device (GPIOB),
|
||
|
|
and configures pins 5 and 8 in output mode. During each iteration of
|
||
|
|
the main loop, the state of GPIO lines will be changed so that one of
|
||
|
|
the lines is in high state, while the other is in low, thus switching
|
||
|
|
the LEDs on and off in an alternating pattern.

Building and Running Project:
|
||
|
|
|
||
|
|
This microkernel project does not output to the console, but instead
|
||
|
|
causes two LEDs connected to the GPIO device to blink in an
|
||
|
|
alternating pattern. It can be built for a nucleo_f103rb board as
|
||
|
|
follows:
|
||
|
|
|
||
|
|
make
|
||
|
|
|
||
|
|
The code may need adaption before running the code on another board.

Troubleshooting:
|
||
|
|
|
||
|
|
Problems caused by out-dated project information can be addressed by
|
||
|
|
issuing one of the following commands then rebuilding the project:
|
||
|
|
|
||
|
|
make clean # discard results of previous builds
|
||
|
|
# but keep existing configuration info
|
||
|
|
or
|
||
|
|
make pristine # discard results of previous builds
|
||
|
|
# and restore pre-defined configuration info
|
||
|
|
|
