I’m trying to read signals from a custom battery solution from user space. I wonder for example how I could probe the BATLOW# signal. The only real help I have found so far comes from here:
where the advice:
You can just read the PMIC REG 0x13 bit3 to know the battery low status.
is given. How would one read this? And also, how would one know the adress? I am guessing that the other non-I2C signals (CHARGER_PRSNT#, CHARGING#, BATTERY_OC#) should also be accessed this way, whereas the I2C-signal could be read and written to by a custom application.
I have tried my best searching for an answer elsewhere but have not succeeded yet.
