Page 3: Compilation Environment Description
Compilation environment description The development environment for the GW3323 chip is “Codeblocks.exe”. For the installation package,“codeblocks-20.03mingw-setup.exe.”. Install CodeBlocks first, then install RV32- Toolchain (When you install ToolChain, the configuration-related compilation environment is registered with CodeBlocks) In the development, we generally use serial port printing or GPIO port and logic analyzer for debugging, breakpoint debugging and simulation are not currently supported. -

1、 Connect the development board with the serial port module of CP2102 or Geehy serial port module. Geehy XLink modue: RX---->Link GW3323 PB3; CP2102 Serial port module：TX -- string 200R -- RX --->Link GW3323 PB3; 2、 The three wires of the serial port module (GND,RX,3.3V) are connected to the development board (GND,PB3,3.3V), and the other end is connected to the USB port of the computer. - Page 14 4、 Then select the project file. dcf, and click Start Download. As shown below: (1) The download file of the routine is in GW3323_ SDK_ V1.0\GW3323_ SDK\projects\Output\bin\gw3323.dcf (2) Select the serial port number of CP2102 serial port on the computer...

Page 16: Example Code Presentation
Example Code presentation 1、 The default routine (GW3323_SDK_V1.0) is "printer test and Bluetooth ". The example program includes: Printer output fixed characters: Press the SW5 button of the development version to control the printer to output "Geety" characters You can also connect Bluetooth to control the printer to output fixed character "Geety" through hexadecimal command ->0x1d34. - Page 17 Debugging Assistant" APP on the mobile phone to connect with the development board. In the program, we put the received data in the ptr array and send it to the computer through the high- speed serial ports PB1 and PB2. w w w.
- Page 18 6、 In this way, we only need to initialize the serial port and wait for the serial port receiving function in the main function to realize the transparent transmission function of Bluetooth. The baud rate is set to 115200, which can also be changed as needed w w w.
- Page 19 7、 In the printer output fixed character program, we initialize each pin of the printer and wait for the flag bit in the printer routine. For example, if the key is pressed and Bluetooth receives fixed data, such as the relevant flag position 1, we let the printer print "Geehy". w w w.
- Page 20 8、 There is also a Bluetooth indicator function in the program, which shows different states by judging whether the Bluetooth is connected. When the Bluetooth is not connected, the LED2 indicator flashes at a frequency of 500ms. When the Bluetooth is connected to the development board, the LED2 is always on to indicate that the connection is successful.
