Features Demonstrated

• cooperative QV kernel
  • with ARM-KEIL toolchain
  • with GNU-ARM toolchain
  • with IAR-ARM toolchain
• preemptive run-to-completion QK kernel
  • with ARM-KEIL toolchain
  • with GNU-ARM toolchain
  • with IAR-ARM toolchain
• Windows emulation (console multithreaded)
• Windows emulation (console, single threaded: win32-qv)

Running the Example

Once programmed into the board, the example blinks the on-board LED about once a second.

Windows Emulation

The Windows emulation is a simple console application that produces the following output:
