High Power Led Driver With Dimmer


Posted on Feb 6, 2014

This application note describes the development and use of a Digital Weigh-Scale (DWS) using Zilog`s Z8 Encore! ® Microcontroller This reference design offers a ready-to-use DWS solution easily scalable to measure high-capacity loads. A high-resolution Analog-to-digital Con- verter (ADC) external to the Microcontroller is used to accurately measu

re the load cell output. The measured weight is displayed on the LCD This reference design is based on the Z8 Encore! MCU which communicates with the 24-bit ADC CS5550 through Serial Peripheral Interface (SPI). The output voltage of the load cell is passed through a Low-Pass Filter (LPF) to suppress any high frequency noise and applied to ADC The measured weight is displayed on a 8 x 1 LCD
