Getting Started with STM32

Although this getting started class will work well for many of the STM32 processors and boards, we will focus on the NUCLEO-F103RB board with its STM32-F103RB processor.

64-Pin NUCLEO Board

• Green LED, LD2, connected to PA5, illuminates when driven high
• Blue PushButton, B1, connects to PC13, grounding the signal when pressed
• 32,768Hz crystal oscillator, LSE, used for Real Time Clock (RTC)
• 8MHz HSE, is provided by the 8MHz crystal oscillator from the attached ST-Link, into PD0
• UART2 connects the target processor to the ST-Link, providing a USB COM port connection on the host computer. Uses PA2 for TX, and PA3 for RX.
• ST-Link connects to TCK (PA14), TMS (PA13)

Processor: STM32F103RBT6

* 128KB Flash
* 20KB SRAM
* 72MHz clock
* Single-cycle multiplication and hardware division
* 2.0 to 3.6 V application supply and I/Os
* Within this part series, this is considered a "Medium-density device",
  and as such, has the following peripherals:
* 3 USARTs
* 3 16-bit timers
* 2 SPIs, 2 I2Cs, USB, CAN, 1 PWM Timer, 2 ADCs
Notes:
   "Low-density device" has fewer peripherals.
   "High-density device" has more peripherals.
