因为手里面有一个ESP-01S的下载器，芯片是CH340的，想着应该能用的话，就暂时不用买ST-LINK或USB转TTL模块了。
烧录时老是忘记细节，每次遇到报错都要排查一遍，特别麻烦，特此记录一下烧录前的检查项。- Sketch uses 14200 bytes (21%) of program storage space. Maximum is 65536 bytes.
- Global variables use 2184 bytes (10%) of dynamic memory, leaving 18296 bytes for local variables. Maximum is 20480 bytes.

嘉立创地阔星开发板STM32F103C8T6
CH340烧录（我这里用的是ESP-01S的下载器）
检查项一
连线
| STM32F103C8T6 | CH340 | | 3V3 | 3V3 | | GND | GND | | A09 (TX) | TXD | | A10 (RX) | RXD |
引脚图
检查项二
跳线帽如下
检查项三
打开STM32CubeProgrammer测试连接。
先选UART；再选Port；最后点connect。如果连接成功，可以关掉STM32CubeProgrammer，防止端口占用。
连接成功如图所示：
检查项四
打开Arduino，检查开发板烧录配置，upload method修改为"Serial"。
烧录成功
附上测试代码- /*
- * Test program for the STM32F103C8T6
- */
- #include "Arduino.h"
- int counter = 0;
- // const int PA1 = 11;
- // const int PA3 = 13;
- void setup() {
- Serial.begin(9600);
- Serial.println("Hello, World!");
- pinMode(PA3, OUTPUT);
- pinMode(PA1, OUTPUT);
- }
- void loop() {
- Serial.println("Hello, World!!!" + String(counter));
- counter++;
- delay(1000);
- digitalWrite(PA3, HIGH);
- digitalWrite(PA1, HIGH);
- delay(1000);
- digitalWrite(PA3, LOW);
- digitalWrite(PA1, LOW);
- delay(1000);
- }
