Hi all!
I'm experiencing problems with the closed loop control in the GUI for DRV8303. The open loop control works flawlessly but in the "Clock Frequency Mode" tab I can't get a single revolution out of the motor.
Both FAULTn and LOCKn are red in the "Clock Frequency Mode", but green in "PWM Modes".
Has anybody some idea on what the problem is? I've followed the simple instructions in the datasheet for the 8303EVM.
Thanks in advance,
Andreas Eriksson
P.S.
I just found out that I can't manually change the SPDMODE register to 0 - freq at all. It tries to write that but bounces back to 1 - PWM after a split second. What am I doing wrong here? I guess some setting aren't compatible.
