Wirelings / RobotZero DC motor difficulty
« on: September 16, 2020, 02:11:18 PM »
Hello, I have the RobotZero board trying to drive a pair of DC brushed motors. I started with the RobotZero Basic Sketch on the tutorial (https://learn.tinycircuits.com/Wirelings/RobotZero_Tutorial/) but figured out quickly the included stepper motor example won’t work with my DC motors.
Next I’m trying to use the code for the TinyShield since it’s using the Attiny841 processor and the DRV8837 driver chip (identical to what’s on the RobotZero). Not having any luck with the MotorDriverBasic sketch included on that page. I’m not reading voltage through any of the 4 lines coming from the motor connector, even after opening the Serial Monitor (and there’s no message saying the driver wasn’t detected) (https://learn.tinycircuits.com/Motors/Dual-Motor_TinyShield_Tutorial/)
Is there an example sketch that will run DC motors on the RobotZero board?
Thanks for the help in advance.
