The charging current is only about 3-5mA, so the charging time exceeds 12H (set by reg67H[5:4]), and thus also interrupts the charging process. I can't fix this problem, please help me!

Please help me!

You want to set the charge current, but it doesn't change after setting it to 1000mA?

khoa21214475 commented 7 months ago

Yes, I set charge current to 1000mA: // Set constant current charge current limit if (!PMU.setChargerConstantCurr(XPOWERS_AXP2101_CHG_CUR_1000MA)) { Serial.println("Setting Charger Constant Current Failed!"); } And Charger Status is Constant Current (CC) But the charging current is only from 3mA to 5 mA, so the charging time exceeds 12 hours so an error is reported through the charger status LED (1Hz blink) and stops charging. Can you help me solve this problem, thank you very much!

Which board do you use? Looks like a hardware issue

lewisxhe commented 7 months ago

This problem has nothing to do with this library. It can be determined to be a hardware problem. Please ask your supplier about the charging method of the AXP2101 you are using. AXP2101 has two charging methods, and the hardware wiring methods are different.
