Hello there,
I am experimenting with the Cybermaster, but is not able to
get the communication line up between the PC and rcx radio tower.
(I use Visual Prolog for programming).
I use 2400bps 8 bit no parity 1 stopbit
I am sending a byte sequence like the following:
0x55 0xFF 0x00 0x10 0xEF 0x10
where the three first bytes are the header,
0x10 is data and 0xEF is complimentary to 0x10
and the last 0x10 is checksum (sum of all data mod 256)
The light on the rcx radio tower is blinking when I send the data
but the light on the rcx is not blinking as it should when receiving data.
I get nothing back to th PC.
Do I need some advice or should I take up collecting stamps?
Thanks
Sten Kvamme

| Take a look at my page to find out how the CyberMaster protocol works (it is not the very same as the RCX), and to find som sample programs in C and Perl that works.
