    Hello LED flashing is arguably the very first development project that

    however, it is interesting to see its variant which exploits the timers

    Hi All, it's been a few years since I last posted here...

    Good to see some embedded tips, especially related to using hardware
    timers compared to the more common spinner blocking delays.

    Lately I have been experimenting with using a polled hardware timer to
    more closely match the delay times of a tethered forth in emulation mode compared to a binary image on the target. Why polled? because the emulator cannot use interrupts.

    In actual use the emulator, (Mecrisp-Stellaris on a STM32F407 Discovery
    Board running Mecrisp-Across.fs) can be up to several times slower than
    the MSP430 Target running the final compiled binary.
