Utilite for testiing metering BL0940 IC

IC circuit parameters: Voltage divider: 270kOhm x 7 and 560 Ohm Current shunt resistor 30mOhm

UART interface. start ./pcuart1

Hello, pcuart1 Found 1 ports /dev/ttyUSB0 /dev/ttyprintk

0- chuese USB to uart 1- tty and click Enter

have output page from IC and calculate Voltage, Current and Active Power

for exit q next measure request Enter
