[oopic] Re: Roboteq motor controller.

Follow my idea and find the problem, if any:

8 bit - no parity trasmission is done by sending 8 bits for every
character with no parity bits.

7 bit - even parity is done by sending 7 bits for every caracter plus
1 bit for parity.

I have to send only a few numbers of charachters and numbers.

For example, if i have to send ! sign, i send Hex 21 (binary
00100001). It already has an even number of bits, so i can simply
send hex 21.

If i have to send ^ sign (Hex 5E - Binary 01011110), it has an odd
number of bits so i need to send 11011110 (Hex DE).

I can make a lookup table to check for the correct hex to send,
withhout calculating anything. Will be a time consuming operation for
the oopic?

(PS. i can't control by r/c radio because of problems with cable
configuration).

Other solution: does exist an ic that accept a serial comunication in
8N1 and reformat it to 7E1? Can a second MC do this for me or i will
create a lot of delays?
