Maximum length for serial text
« on: June 22, 2010, 09:57:10 PM »
What is the maximum number of characters for serial text (w/ the smart board)?

When I send a long string (~40 characters), the ioBridge becomes flaky (the serial doesn't seem to consistently work - some times it just returns a zero, etc.)

Thanks!

Yes, there is a rate limit. You can send around 40-50 characters. The module will process that check of data and allow for more. The RTS pin on the serial smart board will go high when the buffer is full and low when it's ready to take another 40-50 bytes. If you don't want to use the RTS pin you can safely send data every second or so.
