reset SD02B baudrate back to Default Baudrate

Hi Support,

We just bought a SD02B stepper motor driver recently, and i have been playing with it. Unfortunately, i think i have messed up with its baud rate, is it possible for us to hard reset the baud rate. I am electronic background guy, can i know the procedure??

Regards,

Hi, there's a solution in the Arduino UART sample code given in SD02B product page. That part of code is commented. Just uncomment it. If you are using other MCU, what you need is to understand the code and write yours.

The basic concept is to set your MCU to possible baudrate and send command to set SD02B back to 9600. If you're not sure what is the current baudrate of your SD02B, then you may need to make a for loop to test every possibility - from lowest to highest.
