The platform/c64/ directory is used for targeting a Commodore 64 computer. Most things are shared between the 6502-based targets so please consult cpu/6502/README for further details. The following C64 Ethernet cards are supported: - RR+RR-Net: Use driver cs8900a.eth with the address $DE08. - TFE: Use driver cs8900a.eth with the address $DE00. - ETH64: Use driver lan91c96.eth with the address $DE10. In most cases it is desirable to use an emulator for the development and testing of a Contiki application. VICE is especially well suited as it emulates both the RR-Net and TFE Ethernet cards. It is available at http://www.viceteam.org/.
