BlueSMiRF and ATmega32 UART Works!

Pretty cool. I ordered a BlueSMiRF Bluetooth serial modem from SparkFun. It arrived today, and I added it to my desktop ATmega32 breadboard…thing. I got it powered up and bonding with the PowerBook, and I was able to configure the modem using AT commands via ZTerm.

Then I watched some TV, 'cause I'm so freakin' tired.

Then I came back to the BlueSMiRF, and decided to add some serial port code to the ATmega32 firmware. It basically takes a single character off the UART (from '0' to '9'), uses that value as an index into a table, and sets the PWM duty cycle on the motor driver accordingly. Voilá! It works! I now have wireless control over a brushed DC motor.

Cool.
