SH1107 Laowang 2 yuan screen

I bought a 0.96-inch 64x128 OLED screen for 2 yuan from the "Laowang Electronic Digital DIY" store, made the base board myself, and it has been verified and tested for normal use. Screen line number QT1107P12A. i2c four-wire driver, use the sample file SH1107_128x128 of the arduino Adafruit SH110X library to drive it with slight modifications. Using the arduino U8G2 library will also work.

Adafruit SH110X library modification content:

• Will define #define SCREEN_WIDTH 64 // Set the width to 64 pixels
• #define SCREEN_HEIGHT 128 // Set the height to 128 pixels
• If you need a horizontal screen, add display.setRotation(1) after clearing the screen cache; //Rotate the display direction 90 degrees, or set it to 2 and 3, which are 180 degrees and 270 degrees respectively.

U8G2 library modification content:

• U8G2_SH1107_64X128_1_HW_I2C u8g2(U8G2_R1, /* reset=*/ 8); //U8G2_R1 is for horizontal screen use. If you need vertical screen, please change to U8G2_R0

Please modify the resistors R4 and R5 according to the TP61040 documentation. I only have these two matching resistance values ​​on hand, and they can be used normally.
