Std edition Voltampermeter
Profile：Simple voltamperemeter
Description
Simple AVR voltamperemeter, based on INA219, ATmega8, 2481AS 7-segments displays.
Allows you to measure voltage in the range of 0-26V in 0.01V steps, current in the range of 0-3A with a step of 1 mA.
Embdeded calibration with two buttons, recovered in EEPROM.
Configurable dynamic display period and refresh rate.
