Problem with M2 PWM on Romeo v2

Account cancelled 2019-06-27 03:59:20 2004 Views1 Replies
Hello
I have a problem with Romeo v2.2 in Devastator. Well, the DC motor connected to the M2 connectors only works when the PWM signal is set to 255. Anything less than 255 means that the motor is not running. The direction of rotation does not matter. Romeo board is new. The DC motor is operational, since it is working properly when connected to M1. Romeo is also connected to an IR receiving diode (pin 2) and a 433mhz receiver (pin 3, I don't use it yet). I'm using a modified sketch from https://wiki.dfrobot.com/Romeo_V2-All_i ... KU_DFR0225_. Does any of you have any ideas why it does not work as it should?

Please ensure that the jumper on the board is shorted (supports PWM control mode.) and the motor is normal.
Please use this code, if it still can't work, contact us at [email protected] to replace. techsupport
