Hi Sten,

Well, I don't have any stamps to sell you, so perhaps you'd care to take a
look on my website which has examples for the Cybermaster in Visual Basic. I
hope Visual Prolog can use .ocx controls otherwise please mail me for some
adresses of stamp dealers :))

Onderwerp: Communicating with Cybermaster not easy


> Hello there,
> I am experimenting with the Cybermaster, but is not able to

> (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?

In article <008d01be48ad$3aa6ba...-van-dam>, B van Dam <bvandam@westbrabant.net> writes (...) If the protocol for Cybermaster is the same as for RCX, you should alternate the &H08 bit in consecutive commands, otherwise the RCX can ignore them. So if (...)
