Question about PINK...

If all my I/O's are being used on my base controller for the pictured ROBO CHILD at the left, can I use the stamp programming port (SEROUT 16 and SERIN 16) with the PINK unit to control the various functions over the internet?

·Thanks·· Deno

    Not for direct connection. The BS program port is designed for RS232 levels, but even

    if it were generating TTL levels (the TX steals rest level from RX), the signal is inverted,

    and you need true mode. I think you can use a max232 level shifter (this inverts) then

    connect its rs232 side to the BS program port and its TTL side to the PINK.

    To program your BS you would need to disconnect this level shifter from your program port.

    And you can only use 9600 baud,·where as 2400 baud is suggested for the BS, so this may

    fail even if the level shifter operates.

    regards peter
