Continuous Servo Output without BASIC Stamp Intervention using the MoBoStamp-pe

The MoBoStamp-pe BASIC Stamp-2pe motherboard includes two AVR coprocessors for offloading realtime tasks from the onboard BASIC Stamp. A popular candidate for coprocessor control has been the continuous pulsing required by RC servos to keep them on position. This is something the MoBoStamp's AVRs can handle with ease. Attached is a zip containing AVR object code and documentation for a firmware servo controller. In brief, this firmware allows each coprocessor to control and refresh up to four servos, without BASIC Stamp intervention. With two coprocessors, this totals eight servos that can be controlled from one MoBoStamp board. Here's a photo of four of them in action:

Enjoy!

    Is this firmware available somewhere on the Parallax site along with its source code? So far I have only been able to find GPIO firmware.

    I believe the firmware is available at the bottom of the first post in the form of a ZIP file.
