Data bits / Word Length

Hi there,

I am using the ST16C552 chip in a microcontroller to communicate with the Roboteq AX1500 via the RS232 serial port.

The options i have to set are:
<ul><li>Word Length (5 - 8)</li><li>Stop Bits (1 - 2)</li><li>Parity (None, even, odd, mark, space)</li><li>Break Control</li><li>Baud rate counter</li></ul>
The last two can simply be ignored and set to "normal" operation.

Obviously, I set stop bits to 1, parity to even... but is "Word Length" the same as "Data Bits"? The roboteq manual speaks of "data bits", but the manual for my chip speaks of "word length"... should word length be 7 or 8? I am thinking it is the same as data bits and is 7?

Cheers

Use the word lenght parameter and set it to 7-bit.

Excellent... I suspected that would be the case.

Thank you very much for the speedy reply :)
