Ⅰ STM32F103C8T6 Description

STM32F103C8T6 uses a high-performance ARM® Cortex™-M3 32-bit RISC core with a working frequency of 72MHz, built-in high-speed memory (up to 128K bytes of flash memory and 20K bytes of SRAM), rich enhanced I/O ports and connections to two APB bus peripherals. This device contains 2 12-bit ADCs, 3 general-purpose 16-bit timers, and 1 PWM timer, and also includes standard and advanced communication interfaces: up to 2 I2C interfaces and SPI interfaces, 3 USART interfaces, a USB interface, and a CAN interface. The mid-capacity enhanced family operates from 2.0V to 3.6V and covers the -40°C to +85°C temperature range and the -40°C to +105°C extended temperature range. A series of power-saving modes guarantee low power consumption application requirements.

Ⅹ Manufacturer

Founded in 1987, STMicroelectronics (ST) is a new enterprise after the merger of Italy's SGS Semiconductors and France's Thomson Semiconductors. From its inception to the present, ST's growth rate has exceeded the overall growth rate of the semiconductor industry. Since 1999, ST has always been one of the top ten semiconductor companies in the world. The entire group has nearly 50,000 employees, 16 advanced R&D institutions, 39 design and application centers, 15 major manufacturing plants, and 78 sales offices in 36 countries. STMicroelectronics has one of the broadest semiconductor product lines in the industry, from discrete diodes and transistors to complex system-on-chip (SoC) devices, to complete platform solutions including reference designs, application software, manufacturing tools and specifications. There are more than 3,000 types of its main products. STMicroelectronics is a major supplier in various industrial fields, with a variety of advanced technologies, intellectual property (IP) resources and world-class manufacturing processes.

Ⅺ How to Use the STM32 Development Board?

The Blue Pill can be programmed in two ways–

• Using an external USB/Serial converter connected to UART1 pins, which is the default bootloader for this family of boards. It can be programmed using the Arduino software this way.
• STLink USB Dongle – this uses the single-wire debug interface to communicate with the board. This allows it to be programmed using advanced software like Keil/CubeMX. It also allows memory access using the STLink software.

Before programming, it is important to connect the BOOT0 jumper to 1 and press the reset button to put the chip in ‘programming mode’.

Uploading Your First Program

If programming uses Arduino software, the appropriate board files should be downloaded using preferences and boards manager.

Then the correct board must be selected on the board's menu.

Since the built-in LED is on pin 13, just like the Arduino, the basic blink sketch will work on the Blue Pill.
