摘要： DS1050 是由 2 线总线控制 5 位脉冲宽度调制器 (PWM)。这允许单个主机设备来控制达 8 奴隶 （DS1050 和其他 2 线设备） 单 2 线公共汽车上。在此应用程序的说明，这表明 2 线公共汽车通过 PC 串行接口的接口。给定和从达拉斯半导体 FTP 站点下载可用的硬件和软件要求。Maxim > App Notes > Digital Potentiometers Display Drivers Power-Supply Circuits Keywords: fan control, fan speed, brightness control, contrast control, 2 wire bus, 2wire devices, PWM, pulse Dec 17, 2001 width modulator, dc motor, LCD LED backlight APPLICATION NOTE 163 Using DS1050 Programmable PWMs to Control a DC Motor and an LCD LED Backlight Abstract: The DS1050 is a 5-bit pulse-width modulator (PWM) controlled by a 2-wire bus. This allows a single master device to control up to 8 slave (DS1050 and other 2-wire devices) on a single 2-wire bus. In this application note, an interface to a 2-wire bus via a PC serial interface is demonstrated. The hardware and software requirements are given and available for download from the Dallas Semiconductor FTP site. Introduction The D……
