protocol conversion

Overview

This circuit design uses the STM32F042 integrated on-chip peripheral UART2 and CAN interface, and the output connection is made through the level isolation conversion chips ADM3053 and ADM2587. RS485 and CAN levels are electrically isolated, which effectively improves system stability, and the relative cost will be higher. The tasks handled by STM32F042 include the following:
1. Receive data from the RS485 bus, and then send it to the CAN bus after certain format conversion.
2. Receive CAN bus data, and then send it to the RS485 bus after certain format conversion.
