Other Parts Discussed in Thread: DS90UB948-Q1

Hi team,

I'm sorry to bother you. Our customer has the following question and need your help.

The customer's current system is MCU -> ds90ub949-q1 -> ds90ub948-q1 -> display. How to control the brightness of the display at the 949 end? Is this possible? If so, how to control it.

Best Regards,

Amy Luo
