Smart bracelet demo designed based on CH582M chip. Supports BLE 5.3, heart rate detection, blood oxygen detection, attitude angle detection, touch buttons and WCH-Link debugging. The hardware provides schematic PCB reference design, and the software provides basic sensor peripheral drivers.
Hardware solution:
-The main control chip uses CH582M chip, 32-bit RISC-V architecture MCU, with built-in BLE5.3
-LCD screen uses 0.96-inch high-definition IPS display ST7735, I2C DMA transmission
-Uses MUP9250 nine-axis sensor, with wrist-lift detection, step count Calculation and other functions
- blood oxygen and heart rate detection module MAX30102
- DRV2605 motor drive module to realize vibration function
- TTP223 touch button
