SSD1306 Driver for CH592F

This driver is a basic implementation to interface SSD1306 OLED Display with CH592F MCU over I2C protocol.

A Cube is rendered on the screen after the test is complete. This cube is then bounced indefinitely over the edges of the display with varying velocities.

Demo

OLED Test followed by Cube Render:

ssd1306_ch592f.mp4

Usage

1. Install GNU RISC-V Embedded ToolChain

2. Clone the Repo

  git clone https://github.com/ravssh/CH592F-SSD1306

3. Open /src/ssd1306/renderer.h & change display resolution & power configuration.

4. Build It -

  make clean
  make

5. Get WCHISP Flashing Tool

6. Connect the Display to MCU according to the table below

   Pin Number	OLED Pin
   5V	VCC
   GND	GND
   B15	SCK
   B14	SDA

7. Hold the boot button on CH592F and connect it to your PC.

8. Run wchisp info to check if it's detected. We can flash it now.

  make flash

Note

This is only a basic implementation. The code is not polished and may cause some unexpected behaviour. There's no support to display fonts or images. Check out fbiego's implementation for LVGL support here.
