Using dfrobots FIT0458 motors. Even without the gear box on I get a speed() deadband of 0-235 before the motor moves.
DF recommends a 2A driver https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5786/FIT0458.pdf
Do you have any other motors you can test with? You might also double-check the working PWM range for those motors and compare with the pHat
Where can the find the phat pwm range?
I can’t find anything on the AUTO PHAT dc motor PWM
The main thing is that you are only supplying half-power
It is likely standard and hardware-defined, as the only mention in the repo is SparkFun_Serial_Controlled_Motor_Driver_Arduino_Library/README.md at 2fc3acb208b8530e489be425e19da2c347c77662 · sparkfun/SparkFun_Serial_Controlled_Motor_Driver_Arduino_Library · GitHub
Can you explain the reason for 1/2 power?
…the specs from DFRobot say 2A…the Autodriver can only provide 1.2A continuous
The DRV8835 says that is has “Flexible PWM or PHASE/ENABLE INERFACE”
Also at speed(233) I get an output voltage of 0.2V
At speed(234) i get output voltage of 4.6V
Fit0458 data sheet says it can operate at 3v why won’t my Autohat scale down to that?
