Board Designer - Bus Voltage Sensing documentation needed

[shane mattner]

I'm trying to make a custom board project with Board Designer and found the documentation lacking for entering the correct parameters.

The Bus Voltage Divider needs to be equal to 1/(voltage divider ratio). Also, the resistors on the Board Designer are not labelled so I had to guess and reference the wiki.

So for me using a 51k and 4.99k voltage divider I needed a Bus Voltage Divider value of 11.223344V.  This number doesn't make sense to me as an engineering value. There's also no direct documentation for calculating this value either.

From the wiki

https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:Motor_Control_Boards_Description#Bus_voltage_measurement

After calculating this value the bus voltage readings are accurate for me.
