AI 生成的摘要: Current measurement uses a PCB copper trace as a sense resistor, enabling cost-effective sensing where high accuracy is not critical. The voltage drop across the trace converts current to voltage, amplified by a programmable gain amplifier (PGA) and digitized by a 14-bit ADC. Temperature compensation is essential due to the copper trace's temperature-dependent resistance, using an internal temperature sensor. Data buffers average ADC samples to reduce noise, while a memory table stores temperature-dependent resistance values for accurate current calculation. The system performs calibration to offset PGA errors and supports flexible gain settings. Design files include PCB prototype schematics, BOM, and Gerber files for implementation.

AI 生成的摘要: Setup procedures for LIN communication in master mode on RL78/F23 and F24 microcontrollers focus on configuring the UART/LIN module (RLIN3) to operate as a LIN master. The document details hardware clock settings, baud rate (19200 bps), LIN network connections, and relevant special function registers (SFRs) for LIN master communication. It covers error detection mechanisms, interrupt handling, and driver API functions to initialize, operate, and manage LIN communication effectively. The guide includes LIN frame timing, communication status monitoring, and transition between LIN operation modes, ensuring robust LIN master functionality.
