RL78/G24 DC/DC LED 控制评估板

AI 生成的摘要: Burst dimming control uses timers KB3 and RD2 to modulate LED brightness by gating PWM outputs. Timer KB3 generates PWM signals on TKBO00 and TKBO01 pins, which are gated by timer RD2 outputs (TRDIOB1 and TRDIOC1). The duty cycle of RD2 adjusts based on analog input voltages at P22/ANI2 and P147/ANI18, controlling the PWM output period and thus LED brightness. This method enables precise LED dimming by synchronizing PWM signals and gating functions. The sample code runs on RL78/G24 devices with specified clock and voltage conditions, supported by development environments like CS+, e2 studio, and IAR.

AI 生成的摘要: PMBus communication sample software demonstrates master and slave functionalities using the PMBus Master and Slave modules SIS on the RL78/G24 microcontroller. It supports PMBus Specification Rev. 1.4 and SMBus Specification 3.2. The sample runs on the RL78/G24 DC/DC LED Control Evaluation Board, where the master controls LED dimming on the slave board via PMBus commands. The software includes communication formats, command specifications, and application operations such as LED dimming, reading output values, control signals, and write protection. Development environments supported include Renesas CS+ and IAR Embedded Workbench. The document also details hardware setup, software configuration, and operation check conditions.

AI 生成的摘要: The simulation model enables verification of LED lighting control using the RL78/G24 microcontroller on a PC. It simulates constant current and dimming control functions of the LED system, replicating software and hardware operations including PWM output and AD conversion. The model supports efficient development by allowing parameter adjustments before using actual devices. Installation requires MATLAB Runtime and runs on Windows 10/11. The package includes executable files, static and dynamic parameter templates, and documentation.
