9/5/2023 0 Comments Fritzing stepper motor driver![]() ![]() It demonstrates the variable control abilities. This example drives a robot in left and right arcs, driving in an overall wiggly course. The following test is essentially the TwoMotorRobot.ino example from the SCMD library, but with a few minor changes to account for the defaults of the Qwiic Motor Driver.Ĭopy and paste the following code into your Arduino browser and upload. See config table for more information.Ĭlick the image for a closer look Testing the Motors A closed jumper is a '1' and an open jumper is a '0'. The config bits are 4 bits that form a configuration nybble. If UART is being used, the pull-up resistors should be disabled. If multiple I 2C devices are being used, these pull-ups should be disabled on all but one device. Opening these disables theI 2C pull-up resistors used for I 2C communication. There are pull-up enables for I 2C and 4 config bits that select operational mode. There are 2 sets of jumpers to configure on this board. From left to right on the front: B2-B1-A2-A1 ![]()
