I have been monitoring the digitalRead(CHG) for the battery is charging along with digitalRead(PWR). For CHG pin 0 = charging and 1 = not charging. For PWR 0 = battery, 1 = USB powered. When battery powered the CHG will show as 0 (charging)? Is there a reason for this - as it appears to be a fault…

In the schematics this pin is marked as /CHG which indicates active low which will be pulled high when there is a supply coming from VUSB. [image] Without VUSB (indicated by PWR) the 6k2 pull-down will enforce the low level. So only the combination PWR && !CHG will provide the actual charging st…
