According to the data sheet a G120 can source or sink 4ma on a GPIO. However, according to this diagram of the Cobra 3. Pins 1.14 and 1.19 are being used to drive a pair of LEDs that appear to pull 10ma?
I have two pins left on my board to use to drive a status led, P1.16 and P1.17. I’m pretty much out of room to add a transistor or mosfet to drive the thing. Can someone who knows more than me :-[ recommend a resistor value to use, I’d like it to be as bright as possible without risking the pin. I’ve got a bunch of these laying around https://www.digikey.com.au/product-detail/en/lite-on-inc/LTST-C230EKT/160-1187-1-ND/269259.
But if someone were to recommend a different led and resistor pair. I could live with that. I’ve got DigiKey orders I need to do next week any way.
Thanks in advance,
I’ve nearly finished this project and I just couldn’t have done it with out the generous support of this community.
