stm32F103 CAN bus

The STM32F103 microcontroller is a member of the STM32 family of ARM Cortex-M3 based microcontrollers. It is equipped with a CAN (Controller Area Network) interface, which is a popular communication protocol used in automotive and industrial applications.

The CAN interface in the STM32F103 supports both CAN 2.0A and CAN 2.0B protocols, with a maximum data rate of 1 Mbps. It also supports up to two CAN buses, with the ability to operate in both master and slave modes.

The CAN interface in the STM32F103 is equipped with a number of features, including:

- Programmable bit timings, which allow the user to configure the timing parameters of the CAN bus to suit their specific application requirements.
- Automatic retransmission of messages in case of transmission errors.
- Message filtering, which allows the user to selectively accept or reject incoming messages based on their content.
- Interrupt-driven operation, which allows the microcontroller to respond quickly to incoming messages.

In addition to the CAN interface, the STM32F103 also features a range of other peripherals, including ADCs, timers, UARTs, and SPI interfaces, making it a versatile microcontroller for a wide range of applications.
