خانواده STM32 از سری میکروکنترلرهای 32 بیتی مبتنی بر پردازنده ARM Cortex می باشد که با هدف ایجاد معنای جدیدی از آزادی عملکرد برای کاربران میکروکنترلرها ایجاد گشته است. در این خانواده از میکروکنترلرها تلفیقی از کارایی بالا، عملکرد همزمان، پردازش سیگنال های دیجیتال و کاربردهای کم توان در بالاترین سطح کیفی و با حفظ یکپارچگی کامل و سهولت توسعه، ارائه می گردد.از جمله امکانات مهم میکرکنترلر STM32F103C8T6 ، هسته Cortex M3 با سرعت 72MHZ، اینترفیس موازی ، ADC 12 بیتی، DAC 12 بیتی و دارا بودن اینترفیس های متنوعی از جمله USB، Can، I2C، USART، SDIO و … می باشد.
characteristics:
1:on-board-based MCU most basic circuits, such as crystal oscillator circuit, USB power management circuitry and USB interface.
2:the core board raises all I / O port resources.
3:with the SWD debugging emulator download interface, which requires a minimum of 3 lines can be completed commissioning download tasks, compared to traditional JTAG debugging there are a lot of benefits, a plug in here, JTAG and now a great tendency to be phased out, such as ST’s new out of the M0 MCU series to retain only the SWD debug interface, JTAG directly canceled
4:Dimension only traditional DIP40 package (such as AT89S52 ) size, has not yet found on Taobao smaller than our core board the same specifications.
5:the use of current smart phones used Mirco USB interface easy to use, do USB communications and power supply.
6:for the STM32 RTC can not afford to vibration problems, we recommend using the official low-load RTC crystal scheme, and use the Epson brand crystal, without the use of an inexpensive cylindrical crystal.
7:with a high quality 1 * 40 / 2.54mm pitch single row pin ensure excellent conductive contact, user-friendly core board is placed into a standard-purpose board or breadboard. Pin default is not welding, the user can choose according to their needs welding direction.
8:You can use the Keil compiler, IAR compiled by J-Link or USART1
