The SPI-Box offers a "Serial Peripheral Interface" for Personal Computers. It will be connected to the serial port of the PC and allows an up to ten times faster in system programming of microcontrollers. Over and above other peripheral chips with SPI can be connected. The high flexibility and the published sources of the software interfaces allows to adapt the SPI-Box to any system.
