Connecting sensors #503

How do I know which pins to use to connect arbitrary peripherals? I couldn't find anything in the user manual. |
Beta Was this translation helpful? Give feedback.

You will find this information typically in the device's datasheet. The reference manual typically covers a whole family of devices and therefor this information is given in the data sheets which are more specific to individual variants. For example for the STM32F303, table 13, STM32F303xB/STM32F303xC pin definitions gives an overview on which peripheral (UART, I2C, ...) you could connect to which pin. From today's perspective, the STM32F303 is a somewhat older microcontroller where you could connect a function to a small number of different pin sets. Today's controllers often provide more flexiblity. They often allow to connect arbitrary functions and pins. |
