## Onboard Resources
The "blue pill" is a STM32F103 based development board with Cortex-M3 ARM CPU that runs at 72 MHz, 20 KB of RAM and 64 or 128 KB of flash memory. The microcontroller (MCU) has a USB port, two serial ports, 16 bit PWM pins and 12 bit ADC pins. It runs at 3.3V, but some of its pins are 5V tolerant.

This BSP provides MDK4, MDK5, and IAR projects for developers and it supports the GCC development environment. Here's an example of the MDK5 development environment, to introduce how to run the system.
### Hardware connection
### Use ST-LINK Debugger to connect the Blue Pill Board
| VCC 3.3 | **Don't need to connect VCC 3.3 pin** |
| VCC 5 | **Don't need to connect VCC 5 pin** |
1) Use a Type-A to Mini-B cable to connect the development board to the PC and turn on the power switch.
2) Use FTDI adapter(USB to UART) to connect the Blue Pill board's PA9(Tx) and PA10(Rx) pins.
### Make sure Jumper Position (Both 0 Position)
| BOOTx | High / Low |
| :---: | :--------: |
| BOOT0 | 0 |
| BOOT1 | 0 |
### Compile and Download
Double-click the `project.uvprojx` file to open the MDK5 project; compile and download the program to the board.
- Double-click the `project.uvprojx` file to open the MDK5 project (**NOT**`template.uvprojx` file)
- Click the “option for target” button
- Debug: Choose "ST-LINK Debugger" and Click "Setting" button:
- Port: choose "SW (Serial Wire)"
- Flash Download: check "Reset and Run"
- Compile and download the program to the board
### Running Results
After the program is successfully downloaded, the system runs automatically. Observe the running results of the LED on the development board, and you will see the LED is flashing periodically.
The USB virtual COM port connects to USART1(PA9-Tx, PA10-Rx) by default, and when the corresponding serial port (115200-8-1-N) is opened in the terminal tool, the output information of RT-Thread can be seen when the device is reset:
