Template: TCS34725 Color Sensor STM32 Guide
From Waveshare Wiki
The STM32 examples are based on the STM32F103RBT6 and the STM32H743. The connection provided below is based on the STM32F103RB. If you need to use other STM32 boards, you may need to change the hardware connection and port the code yourself.
STM32
Hardware Connection
| Sensor | STM32 | Description |
|---|---|---|
| VCC | 3.3V | Power input |
| GMD | GND | Power ground |
| SDA | PB9 | I2C data input |
| SCL | PB8 | I2C clock pin |
| INT | PB4 | Interrupt output (open drain output) |
| LED | PB10 | Light emitting diode |
Examples
The examples are developed based on the HAL libraries. Download the Demo codes archive to your PC. Unzip and find the STM32 project from TCS34725_Color_Sensor_code\STM32\XNUCLEO-F103RB\MDK-ARM.
- Open the TCS34725_Color_Sensoc.uvprojx file by Keil.
- Build and the project.
- Program the project to your STM32 board.
- Connect the UART1 of your STM32 board to the PC and check the serial data with SSCOM software.
