HSO on G431

[sst1010]

Hi,

I'm trying to setup HSO on the G431, I used the B-G431B-ESC1 board as a starting guide. I'm trying to use differential sensing with internal OP-AMPs and internal PGA. I have split the currents and phase voltages across ADC1 and ADC2 but I still cannot get the HSO option to show up with MC workbench. I'm using the latest version. I have attached my board JSON file, any guidance will be appreciated.

Thanks,

Ray

Hello sst1010,

When it comes to the Internal OPAMP topology, the HSO currently only supports the ThreeShunt_RawCurrents_Differential_ExternalGain_FilteredADCInput hardware variant. Apart from that, your ADC layout is correct.
