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)
