Hello all,
So I have a dual color LED (Red + Green) that share a common GND. So it is essentially 2 anodes (1 for each colour) and the common GND.
I want to use the 2 pins from the TP4056 (Pin 6 STBY & 7 CHRG) to drive the dual anode LED. Right now, the charge board has 2 separate LEDs. When the system is charging, pin 7 (CHRG) is pulled to GND. A RED LED connected from VCC to Pin 7 through a resistor is turned on.
When charging is done, STBY is pulled low, CHRG goes High-Impedance and a Blue LED turns on (connected from VCC to Pin 6 through a Resistor).
How would I use my dual Anode LED with common GND since both status pins go low to GND?
