Charlieplexing with MOSFET's, how?
I need to drive 36 heatwires (200ma each) with a microcontroller.
I understand charlieplexing with LEDS. The basic idea behind that is the inputs can have at tri-state. (if I fully get it).
In case of my mosfets, the intput (Gate) can never float, the gates are always connected with a 10K resistor to GND.
How can I use charlieplexing and MosFETS?
