Hi
We need to upgrade our BLDC speed controller with 16bit MC56F8135 to 32bits DSC like 81XXX or 82XXX. I have the EVK boards such as MC56F81000-EVK and TWR-56F8200 with FRDM-MC-LVBLDC and APMOTOR56F8000e. Any demo code for my upgrade project with my kits
I also saw a good demo as below

Any demo code for it?
Best regards,
Fred

Hi, Fred,
As you know that there are two on-chip OPAMPs for MC56F81xxx family, if you use the MC56F81000-EVK plus FRDM-MC-LVBLDC , the on-chip two OPAMPs are not used, we have not the example code to control BLDC with the two OPAMPs involved.
If you are interested in the OPAMP utilization, we have the example code in SDK package:
...........\SDK_2_10_0_MC56F81000-EVK\boards\mc56f81000evk\driver_examples\opamp
You can download the SDK package for MC56F81xxx from the link:

BTW, there are two dedicated OPAMP on the FRDM-MC-LVBLDC, I suppose that you can use the on-chip OPAMP to replace them.
Hope it can help you
