Multi-Instrument Digital Assistant – PIC16F84A

Multi-Instrument Digital Assistant - PIC16F84A - "It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver."

The Engineer's Assistant - Erik Grindheim

"This compact instrument is intended to be a digital laboratory tool for hardware and, in some cases, software debugging. It contains four instruments in one unit: logic probe, single channel logic state analyzer, frequency counter and serial code receiver"

Multi-Instrument Digital Assistant – PIC16F84A

Serial code receiver The serial code receiver receives 42 bytes and displays them in both HEX and ASCII. The baud rate is selectale in 8 steps from 1200 to 115200.

Logic state analyzer This is a one-channel logic state analyzer. It fetches 300 single bit samples in a selectable rate from 25ms to 1┬ÁS (40 Hz to 1 MHz in 16 steps).

Frequency counter The frequency counter displays the frequency with up to 8 digits on the LCD. The refresh rate is 500ms.

Small Electronic Testing Tools

Logic probe The low and high logic levels are displayed by LEDs which are OFF if the probe tip is floating.

gEDA Project - Electronic Design Automation

The gEDA project is working on producing a full GPL'd suite of Electronic Design Automation tools. These tools are used for electrical circuit  design, schematic capture, simulation, prototyping, and production.

gEDA  - Electronic Design Automation

Currently, the gEDA project offers a mature suite of free software applications for electronics design, including schematic capture, attribute management, bill of materials (BOM) generation, netlisting into over 20 netlist formats, analog and digital simulation, and printed circuit board (PCB) layout.

How to Use Your PC to Measure Temperature

Thermocouple, RTD, Temperature monitoring is central to the majority of data acquisition systems, be it to save energy costs, increase safety, reduce testing time...whatever your reasons, you will need a device to measure the temperature - a temperature sensor.

How to Use Your PC to Measure Temperature

Thermocouples, resistance temperature devices (RTDs), thermistors and infrared thermometers are all types of temperature sensor. Which you choose depends on factors like your expected maximum and minimum temperatures, the accuracy you need and your environmental conditions.
