STM32 example

Protocol Support

Protocol / frame	Support	How this example handles it
0x91 IMUSOL	Supported	Decodes a single-device float frame into receive_imusol and prints it from dump_data_packet().
0x62 GWSOL	Supported	Decodes gateway float collection frames and iterates receive_gwsol.receive_imusol[].
0x63 GWSOL Compact	Not supported	The STM32 decoder has no compact gateway branch.
0x90, 0xA0, 0xB0, 0xB1, 0xC0, 0xD0, 0xD1	Supported	Parses loose single-field output modes.
0xF0 Pressure	Skipped	The code advances past the pressure item and does not store or print pressure.

This example provides C language example code, users receive Hi226/Hi229 and Hi221 data.

• Test environment: Windows10_x64 operating system

• Compiler: keil_V5.28

• Development board: Punctual Atom-Battleship V3 STM32F103ZET6

• Test equipment: Hi226/Hi229

Hardware connection

Insert the Hi226/Hi229 into the SuperCore debug board correctly.

Supercore Debug Board	Punctual Atomic Development Board
RXD	PA2(TXD)
TXD	PA3(RXD)
3.3V	3V3
GND	GND

Connect the corresponding pins in the table above with DuPont wires.

Plug the USB cable into the USB_232 socket of the development board, and plug the other end into the computer.

Watch the output

Open the serial port debugging assistant, open the serial port number corresponding to the development board, and observe the data output
