The main purpose: It can be used for 2B or 3B or 3Band or 4B full range of development boards, for , C51, STM32 and other platforms. The provides programs that can display CPU, temperature, memory, hard disk occupation, IP address and other information. The OLED screen pin header has been soldered, and the finished line is optional, which can be directly connected to the for . High resolution: 128x64 same resolution as 12864, high Viewing angle: 160 Power consumption: normal display 0.06w far lower than TFT display Wide voltage power supply 3V-5V, compatible with 3.3V and 5V level logic, without level conversion chip IIC interface only needs 2 IO to light up easily. Working temperature range is industrial grade -20-70 -grade process standards, long-term stable work. Instructions for use: 1. Correct wiring Pins on the module for GPIO VCC 5V or 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 for and download the data to the home or pi directory of the for . 3. Compile the program file gcc -o oled oled.c ssd1306_i2c.c -lwiringPi Among them, the gcc compiler is called, -o means the generated file, followed by the generated file name, oled.c and ssd1306_i2c.c are programs, and -lwiringPi refers to the wiringPi library of the . 4. Run the program . or oled At this point, you can see the CPU occupancy rate, CPU temperature, running memory occupancy rate, disk occupancy rate and IP address of the displayed on the oled screen. Due to different batches, there may be differences in product appearance, color, and printed text, which not affect the use.
