STM32F103C8T6 development board, program arm stm32 arduino

Intro for STM32F103C8T6

The STM32F103C8T6 is a development board for the ARM Cortex-M3 processor, designed to provide a low-cost platform that can still meet the requirements of many developers. These board's features make it ideal for a wide range of applications such as motor control, power management, medical and handheld equipment, PC and gaming peripherals, GPS platforms, industrial applications and more.

STM32F103C8T6 medium-density performance line family incorporates the high-performance ARM Cortex-M3 32-bit RISC core operating at a 72 MHz frequency, high-speed embedded memories (Flash memory up to 128 Kbytes and SRAM up to 20 Kbytes), and an extensive range of enhanced I/Os and peripherals connected to two APB buses. All devices offer two 12-bit ADCs, three general purpose 16-bit timers plus one PWM timer, as well as standard and advanced communication interfaces: up to two I2Cs and SPIs, three USARTs, an USB and a CAN. The devices operate from a 2.0 to 3.6 V power supply. They are available in both the –40 to +85 °C temperature range and the –40 to +105 °C extended temperature range. A comprehensive set of power-saving mode allows the design of low-power applications.

Tutorial to Program STM32F103C8T6 ARM STM32 arduino

STM32F103C8T6 is a very cheap but very fast ARM STM32 micro controller. You can run simple sketches very easy by following the steps below. 1. Download the latest Arduino IDE from arduino.cc and extract it. You can also download the Arduino IDE .exe file and install it to your computer. 2. After downloading the file from this link, extract it and copy the Arduino_STM32-master to your Arduino / hardware folder that you extract in the first step. If you have downloaded the .exe file then go to C:\Programs\Arduino\hardware. 3. Run the Arduino IDE, choose settings: 'Board: Generic STM32F103C series' 'Variant: STM32F103C8 (20k RAM, 64k Flash)' 'Upload method: Serial' 'Port: <the COM port of your USB-to-serial adapter>' 4. Go to File->Exampls A_STM32_Exampls->Digital->Blink and change the PB1 to PC13. 5. Put Boot1 to 1 by moving the jumper for 0 to 1, Press the Reset button and hit Upload on the Arduino IDE. After uploading if all went well the LED will blink every 100ms. Put Boot1 to 0 again so the next time you power up the micro controller the program will star automatically. You can also try to read an analog value. Go to File->Exampls A_STM32_Exampls->Analog->AnalogInSerial. Change the const int analogInputPin = 15; to const int analogInputPin = PA0; and hit upload. Open the Serial Monitor on the Arduino IDE, the value will be from 0 to 4095, it has 4 times the resolution of an arduino.

Features of STM32F103C8T6

Embedded Flash memory

- Up to 128 Kbytes of embedded Flash is available for storing programs and data.

Embedded SRAM

- Up to 20 Kbytes of embedded SRAM accessed (read/write) at CPU clock speed with 0 wait states.

Boot modes

At startup, boot pins are used to select one of three boot options:

- Boot from User Flash

- Boot from System Memory

- Boot from SRAM

The boot loader is located in System Memory. It is used to reprogram the Flash memory by using the USART.

Power supply schemes

- VDD = 2.0 to 3.6 V: external power supply for I/Os and the internal regulator. Provided externally through VDD pins.

- VSSA, VDDA = 2.0 to 3.6 V: external analog power supplies for ADC, Reset blocks, RCs and PLL. In VDD range (ADC is limited at 2.4 V).

- VBAT = 1.8 to 3.6 V: power supply for RTC, external clock 32 kHz oscillator and backup registers (through power switch) when VDD is not present.
