Blok diagram of the hole setup 2010. This diagram show the different communication lines between the modules. Central stay the CPLD module from Terasic as peggyback module on the global interface Board. This interface board contains now an extra AVR controller, the ATmega328P,The wireless RFM12B module for the external flashes, the realtime clock module and the temperature sensor. External there are the shuttermodule, the optical detector module and the central display module. All this lines are SPI lines at high speed (2 MHz). Electrical shemas are now ready, time now to make the PCB layout. Within 2-3 weeks I hope the have the PCB layout ready.
