==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: 

{| class="wikitable" style="width:400px; "

|-

|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: 

{| class="wikitable" style="width:400px; "

|-

|Link debugger || STM32 minimum development board

|-

| GND || GND

|-

| SWCLK || CLK

|-

| SWDIO || DIO

|-

| 3.3V || 3.3V

|} 

Then select the firmware for burning 

3. Program debugging: After connecting the Link burner in the above way, click the "Debug" key 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

4. Module Function Testing

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

{| class="wikitable" style="width:400px; "

|-

|Display module || STM32 minimum development board

|-

| GND || GND

|-

| 3.3V || 3.3V

|-

| SCL || PA5

|-

| SDA || PA7

|-

| B || PA1

|-

| A || PA2

|-

| D || PA3

|-

| S1 || PA4

|} 

Then power on, as shown in the picture:

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;
