I have been more than a week trying to use unsuccesfully this board combination to develop some FOC solution for big brushlesss motors.

How to I sync two SPV1040 solar charger ICs connected in parallel so that both of them have the exact voltage set point?

I am using 2 SPV1040 that are controlling 1 solar panel per chip. With that said, I am using a super cap with no battery and when the super cap is discharged the two ICs work in unison to charge the Super cap to the voltage set point. Once that is co...

L6470 absolute position counter

Hi all,I have questions about L6470 absolute position counter:Can it be used reliably to count how many steps (or micro steps) the motor actually spins? For example, when at ABS_POS 0, if executing GoTo_DIR(1, 25600) (1/128 micro step mode), does it ...
