OpenGolfMat aka automatic tee up

This time me and marabo have realized what so called an ‘Automatic Tee Up’, which is a device used in golf practice. The device is controlled by an AtMega16 microcontroller and an open source software written by myself and (sooner or later) available on-line. We are currently looking for sponsors who want to put in test this device on the field and give us feedbacks. What need to be done

Test counter0 on atmega16

These programs illustrate the use of time counter 0 on a AtMega 16 MCU, AVR libc and avr-gcc. In this example we have a 4Mhz external clock connected on an stk500 dev kit. If you use a different clock speed, please fix the FCPU value in the Makefile or in GCC flags. GIT repository to clone You can clone from my git repository to download the source code and eventually bugfix and patch.
