Raspberry Pi 4 0.96 inch OLED I2C 4-pin LCD Screen Module Displays CPU

Raspberry Pi 4 0.96 inch OLED I2C 4-pin LCD Screen Module Displays CPU Temperature Hard Disk Information for STM32

Note: Please tear off the upper protective film of the case.

Introduction:

It can be used for the Raspberry Pi 2B\3B\3B+\4B full range of development boards, for , C51, STM32 and other platforms. The Raspberry Pi provides programs that can display CPU, temperature, memory, hard disk occupation, addre and other information.

The OLED screen pin header has been soldered, and the finished line is optional, which can be directly connected to the Raspberry Pi.

Product weight (including packaging): 8(g)

Instructions for use:

1. Correct wiring

Pins on the module Raspberry Pi GPIO

VCC 5V/3V (red wire)

GND GND (black wire)

SCL SCL (yellow line)

SDA SDA (blue line)

2. Install the WinSCP tool on the computer, connect to the Raspberry Pi and download the data to the home/pi directory of the Raspberry Pi.

3. Compile the program file

gcc -o oled oled.c d1306_i2c.c -lwiringPi

Among them, the gcc compiler is called, -o means the generated file, followed by the generated file name, oled.c and d1306_i2c.c are the source programs, and -lwiringPi refers to the wiringPi library of the Raspberry Pi.

4. Run the program

./oled

At this point, you can see the CPU occupancy rate, CPU temperature, running memory occupancy rate, disk occupancy rate and addre of the Raspberry Pi displayed on the oled screen.
