e) Minimum Development Board Burning Instructions

1. Program burning - USRT: Prepare a USB to TTL module (such as CH340) to plug into the computer's USB port, and then prepare an STM32 mini development board. The connection method is as follows:

TTL serial port module	STM32 Minimum Development Board
GND	GND
TX	RX
RX	TX
3.3V	3.3V

Then plug in the jumper cap between the BOOT0 pin and 3.3V to burn the firmware;

2. Program burning - SWD: Prepare a Link debugger (ST Link, J-Link, etc.) to plug into the USB port of the computer, and then prepare an STM32 mini development board. The connection method between Link and the development board is as follows:

Link debugger	STM32 Minimum Development Board
GND	GND
SWCLK	CLK
SWDIO	DIO
3.3V	3.3V

Then select the firmware for burning;

3.Debug: After connecting the Link burner in the above way, click the "Debug" button of the compiled software, select "ST Link", and then click Settings;



If the SW Device displays a device, it means that the debugger has successfully recognized it. Set the parameters according to the following figure and click OK.



Then press Ctrl+F5 or click the debug button to start debugging:




4. Module function testing

After the burning is completed, connect the OLED display module to the minimum development board according to the following table:

Display module	STM32 Minimum Development Board
GND	GND
3.3V	3.3V
SCL	PB8
SDA	PB9
S4	PA10
S3	PA9
S2	PA8
S1	PA7

Then power on, as shown in the figure:



When no button is pressed, the screen will display "0";

When pressing S1, S2, S3, and S4, the screen will display "1", "2", "3", and "4" respectively;

          

             

The above tests show that everything is normal on the module.
