This program measures the current and voltage from a bench power supply using 4 of the ADC channels on an AVR (an ATmega328p in my case) and displays the readings on a 2x16 character LCD based around the Hitachi HD44780 LCD controller.
The display driver was implemented with only the most basic functions of the device (setup, write to screen, and move around some). To save on pins, 4-byte mode is selected in the initialization of the display.
In the circuit implementation, voltages were stepped down to 0-5V range using op amps. The current measurements are based on the output of a difference amplifier taking input from either side of a test resistor.
