I need help with changing the MP8869S reference voltage. I was able to established connection with the board, and also able to change frequency and current limit. however, I couldn’t change the reference voltage from the GUI. Please help to look into this, thanks.
The reference voltage bit is locked by default for safety reasons. To unlock it, we first need to write ‘1’ to the Go_Bit on reg 01h[D6]. You will then be allowed to change the reference voltage. Please note that Go_Bit will clear every time a new reference voltage is written. This bit will need to be set again before changing the reference voltage.
