CAN Bus Communication and Control

This project implements an embedded CAN communication system on an STM32F10x microcontroller. The system integrates button inputs, LED control, ADC sensing, and CAN bus messaging to demonstrate bidirectional communication between nodes on a CAN network.

The program initializes the system clock, GPIO interfaces, ADC module, timer, and CAN controller with configured message filters. Two push buttons are used to control system states: a wake-up button and a user button, each updating corresponding LEDs and broadcasting their status over the CAN bus using predefined message identifiers.

Once the system is initialized, a timer periodically triggers the transmission of ADC sensor readings over CAN. The ADC value is read from an analog input channel, packaged into a CAN message, and transmitted to other nodes on the network.

The system also supports receiving CAN messages, which are parsed and used to control external LEDs (LED8 and LED9). Incoming messages are filtered by identifier and processed to determine whether the LEDs should be turned on or off based on the received data payload.
