ADC selection for HSO sensing
Hello ST
Im trying to generate a HSO compatible FOC board using the STM32G747CEUx but I am not able to select the HSO option for Speed sensing.
I've seen the requirement of using atleast two different ADCs for the current sensor and voltage measurement
Therefor I have assigned ADC1 and ADC2 for current measurement
And ADC3, 4 and 5 for voltage measurement
But I am not getting a solution for this.
Here is my json design file
Thank you
