電源供應(yīng)器與數(shù)字電位器校準(zhǔn)應(yīng)用筆記

Abstract: A resistive feedback network is often used to set the output voltage of a power supply. A mechanical potentiometer (pot)conveniently solves the problem of adjusting a power supply. For easier automatic calibration, a mechanical pot can be replaced witha digital pot. This application note presents a calibration solution that uses a digital pot, because digipots are smaller, do not movewith age or vibration, and can be recalibrated remotely. This proposed solution reduces the susceptibility of the system to thetolerance of the digital pot's end-to-end resistance, making the solution optimal fordesigners. This application note also explainssome of the equations required to calculate the resistor chain values and to use a digital pot in this way. A spreadsheet withstandard reisistor values is available for easy calculations.

Microchip PIC系列單片機RS232通訊應(yīng)用

Digitemp Junior – An RS-232 Port-Powered Digital Thermometer Digitemp Jr. is a device that is designed to measure and report ambient temperature. When connected to an RS-232 port on any PC, it will periodically measure and report in ASCII form the ambient temperature in degrees Celsius. These temperature readings can be monitored with any terminal program. If the terminal program supports capture to disk, the temperature readings can be saved to disk for further analysis with a spreadsheet program or other data analysis tool. The simple ASCII output format of Digitemp Jr. makes it rel- atively easy to write custom software for receiving, recording, and analyzing ambient temperature data. Best of all, Digitemp Jr. requires no external power sup- plies or batteries. It is powered directly by the RS-232 port.

雅馬哈機器人操控軟件VIPplus

VIP+ is support software for YAMAHA RCX series robot controllers. In addition to the functions of the previously released "VIP Windows" software, VIP+ includes an easy-to-use GUI (graphical user interface). VIP+ also allows control by 2 or more controllers or access to a controller from 2 or more clients via Ethernet connection. ● With VIP+ you can: ? Do offline editing of all data used on robot controllers ? Operate and monitor robots connected to robot controllers ? Do online editing of all data used with robot controllers ? Back up and restore robot controller data ● Functions and features newly added to VIP+: ? Ethernet connection to controllers ? Supports data input in spreadsheet software format ? Seamless backup and restoring of controller information such as point data ? Syntax coloring ? Data transfer between the online controller and an offline document by drag & drop ? Executes online commands using a terminal window ? Controller tree and document tree functions similar to Windows Explorer
