Hi :
[VERSION]: MCSDK 6.3.1
I have some questions regarding the HSO ADC sampling configuration. I am currently using a custom PCB to validate the HSO algorithm with the STM32G431 chip. ADC1 and ADC2 are used to sample voltage and current separately. The sampling configuration is as follows: ADC1 performs four samples for current U, current W, voltage U, and temperature. ADC2 performs four samples for current V, voltage V, voltage W, and bus voltage. After reading the HSO Start-up document, I noticed that the Ksample delay parameter is affected by the sampling order. I am unsure whether my ADC configuration is correct. If it is correct, my switching frequency is currently 16k. What should the Ksample delay be? Should I modify the ADC1 sampling to current U/V/W/temperature and the ADC2 sampling to voltage U/V/W/bus voltage?
