MCP, EFIS, MIP, SimVim, knobs and the throttle quadrant

The original prototype of the radio panel backplane PCB used almost all pins of an Arduino Mega. To get more inputs and outputs available, the authors of SimVim introduced the use of multiplexers for inputs and 7-segment display driver clocks and updated their software so that multiple LED drivers can be daisy-chained for up to … More MCP, EFIS, MIP, SimVim, knobs and the throttle quadrant
