The RTX_Blinky project is a simple RTX Kernel based example
|
|
for a simulated Cortex-M3 device
|
|
|
|
Example functionality:
|
|
- Clock Settings:
|
|
- XTAL = 50 MHz
|
|
- Core = 25 MHz
|
|
|
|
The simple RTX Kernel based example simulates the step-motor
|
|
driver. Four LEDs are blinking simulating the activation of
|
|
the four output driver stages
|
|
The simulation does not provide LEDs, so the state changes
|
|
are output on the Debug printf window:
|
|
|
|
- phase A
|
|
- phase B
|
|
- phase C
|
|
- phase D
|
|
|
|
This example simulates Half step driver mode and
|
|
CW rotation direction.
|
|
|
|
|
|
The BLINKY example program is available for one target:
|
|
|
|
Simulation: configured for a simulated on-chip Flash
|
|
|
|
The example is compatible with other Cortex-M class devices.
|
|
Simply open the project settings, navigate to Device tab and
|
|
select another Cortex-M class device.
