I have a question about the 4LED display.
I would like to realise the following operations.
Permanent light when SW is on.
I want to show the LED during charging.
This is a simple question, please answer.
Hello Yusa,
Through the battery gauge it seems like you don't have the capability to light up a LED when the cells are charging. Below I've attached the LED Display section in the TRM that shows you what you are able to do within the system. Best suggestion is to read the data stream for when the current is being applied to the system from the host end and allow the host to drive a led for when the cells are charging. I've also attached a section for how the MCU interacts with the battery gauge.

Thank you,
