Developing an ammeter based on a 51 microcontroller

This USB power meter, based on the STC8H1K17 main controller and sampling the INA180, can detect the main circuit voltage and current, D+ and D- voltages, display running time, real-time power, and power consumption statistics. It includes a button to clear running time and power consumption statistics. It also features a PD decoy function.

Summer is here, and electricity consumption is increasing as various appliances are used more frequently. This led to the creation of a power meter to calculate electricity usage. This project references https://oshwhub.com/l1009184289/usb-dian-y. The main
control
chip is an STC microcontroller, and the current sampling chip is a Texas Instruments INA180. This chip can detect the main circuit voltage and current, D+ and D- voltages, display running time, real-time power, and current flow statistics. It also includes a button to clear running time and power statistics, and a CH224K decoy chip that supports both type and type input. The circuit features a Type-C input and a button for configuring the CH224K spoofing voltage. The screen uses a 0.96-inch ST7735TFT (the spoofing program function is not yet written;
the schematic design description includes:
the first part is the power supply section and INA188 sampling circuit design;
the second part is the Type-C input and CH224K spoofing circuit design;
then the DC-DC circuit uses an ME3116 step-down chip
connected in series with a 10k resistor for voltage division and sampling;
finally, the main control and screen circuit
PCB design description includes
a two-layer board with color silkscreen printing
; software description;
physical demonstration description;
and precautions.
Reproduction is not recommended at this time.
A demonstration video is also available.)
