Pulse Counter


The PCNT (Pulse Counter) module is designed to count the number of rising and/or falling edges of an input signal. Each pulse counter unit has a 16-bit signed counter register and two channels that can be configured to either increment or decrement the counter. Each channel has a signal input that accepts signal edges to be detected, as well as a control input that can be used to enable or disable the signal input. The inputs have optional filters that can be used to discard unwanted glitches in the signal.

Advanced 1-Wire Master with Memory #DS2485

DS28E18 Setup Guide for Remote I 2 C and SPI Sensors Featuring the DS2485 It is well established that the I 2 C and SPI communication protocols are designed to be used in short-distance, intra-board communication. This application note discusses the I 2 C and SPI bus extending capabilities of the DS28E18 1-Wire ® to I 2 C/SPI Bridge with Command Sequencer. Specifically, it covers important measures for setting up a long line, e.g., 100m communication with multiple I 2 C and SPI sensors and the benefits of using this device. Introduction The I 2 C and SPI communication protocols are well known to have short bus distances that range no more than a couple meters. Although solutions currently exist for extending these ranges, they are often complex and expensive. The DS28E18 , however, is a cost-efficient bridge-chip device that demonstrates the benefits of using the 1-Wire interface to get the most range out of complex I 2 C and SPI devices such as environmental sensors,...
