STM32 Blue Pill (STM32duino) STM32F103C8

环境配置

1. 安装Arduino环境, 版本1.8.13
2. 下载Arduino_STM32并Arduino_STM32xxx文件夹解压到Arduino安装路径下：C:\Program Files (x86)\Arduino\hardware
3. 安装驱动(Maple DFU driver & Maple Serial driver)，运行路径C:\Program Files (x86)\Arduino\hardware\Arduino_STM32\drivers\win下的install_drivers.bat，安装成功提示：（请勿连接硬件，否则信息会有区别）

请按任意键继续. . .

1. 打开Arduino环境，执行以下几个步骤

• 选择 “工具 -> 开发板:“xxxx” -> Generic STM32F103C series”
• 选择 “工具 -> Variant:“xxxx” -> STM32F103C8(20k RAM, 64k Flash)”
• 选择 “工具 -> Upload method:“xxxx” -> STM32duino bootloader”
• 选择 “工具 -> CPU Speed(MHz):“xxxx” -> 48Mhz(Slow - with USB)”
• 选择 “工具 -> Optimize:“xxxx” -> Smallest (default)”

test.ino

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin PB1 as an output.
  pinMode(PC13, OUTPUT);

  Serial.begin(115200); // Ignored by Maple. But needed by boards using hardware serial via a USB to Serial adaptor
  Serial.println("setup");
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(PC13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(100);              // wait for a second
  digitalWrite(PC13, LOW);    // turn the LED off by making the voltage LOW
  delay(100);              // wait for a second

  Serial.println("Hello world! This is the debug channel.");
}

STM32 Blue Pill 第一次配置（烧录BootLoader）

烧录bootloader后，初次将硬件连接电脑并打开设备管理器，可看到libusb-win32 devices -> Maple DFU设备，此时硬件板卡状态还处于USB DFU设备类状态。
