manirajanvn commented 2 years ago

Hello, I m using teensy 4.0, L298N(GENERIC_2_IN_MOTOR_DRIVER ), GY-85 and rplidar. After upload firmware to teensy, was using teleop to test. when I press u, i, o wheels are rotating in forward and when I press m, ,(comma), .(dot) wheels are not rotating in backward. Just want to know is this expected or Am I missing something. Please find the attached driver image and config

Thanks Mani

Hey @manirajanvn ,

Are the wheels not spinning backwards during calibration too or this behavior only happens with the firmware (w/ microros)?

manirajanvn commented 2 years ago

Hi, Wheels are rotating forward separately for spin and sample commands during calibration.

Hmm, this could be hardware related. Can you confirm that the L298's GND shares the same ground with the Teensy?

Hi, This issue is resolved, have missed L298's GND to Teensy. Thanks
