E-Wheelie: Changing the crystal...

[bluebear]

Hey.

Im doing a project where im trying the make a interface with the TX/RX on the ATmega32. I was just woundering if it would have any effect on the circut or timing if the crystal was changed out? Im communicating with 115200 baud, and with a 16MHZ clock i get a error of 3 %.

Hello Lars,

i am building a Telemetry for the wheelie at the Moment.
This uses the USART, too.

Using the USART has no effect to the rest of the Wheelieprogram, but it is not necessary to send data in highest speed.
3% is no Problem

An article in Elektor is planned in the near future.

Nice job hehe.. good to see some cool Wheelie geeking

Im making the wheelie connect to a robot platform we are using. And for this im adding encoders to the wheels. The encoder information and other informations are transmitted over a rs485 bus. So the baud rate is fixed at 115200.

ill post some pictures and stuff if u like when done

And thx for your reply... Its quiet nice what you have done.
