The methodology of the process has as its first stage an analysis of commercial devices with similar functions, aiming to define a cost limit to the project, followed by a stage of study of technologies and purchase of components. The following development stages include the part of communication and definition of the protocol between device and computer, development of the firmware for circuit testing and the software for user interface and prototype assembly. The project was develop in two modules. The first module consists in a digital electronics lab using a LPCXpresso 1343 ARM-based microcontroller, in which the firmware was programmed in C language for USB communication with the computer and applying and sampling of the digital signals defined by the user in the following configurations: 8 inputs/8 outputs, 4 inputs/12 outputs, 12 inputs/4 outputs, 16 inputs and 16 outputs. The prototype features 4 KB reserved to circuit testing data storage and maximum sample rate of 1MS/s. The second module, which covers the software developed for the computer, was programmed in JAVA language, providing communication with the prototype and user interface, allowing the definition of the input digital signals to be applied and the viewing of the output digital signals made with the data sampled by the device. The technologic result consisted on the development of a digital circuit test device that, instead of mechanic switches and LEDs, uses an interface with a computer. The socioeconomic result of this project reveals itself in the composing of a prototype with cost below R$300,00, 70% less than the R$1000,00 of the average cost of digital circuit test devices in Brazil, what can ease the purchase of this equipment for education institutes or even for the students who wish to set up their own home labs. O objetivo deste trabalho é desenvolver e avaliar um protótipo de mesa digital computadorizada de custo acessível para teste de circuitos digitais. A metodologia do desenvolvimento do projeto contou com uma etapa de análise de concorrentes para definir um preço máximo para o custo do projeto, seguido de uma etapa de estudos de tecnologias e compra de componentes. As etapas seguintes de desenvolvimento contemplaram a parte de comunicação e definição de protocolo entre o protótipo e o computador, desenvolvimento do firmware para teste de circuitos e do software para interface com o usuário e montagem do protótipo. O projeto foi desenvolvido em dois módulos. O primeiro módulo consiste em um protótipo da mesa digital utilizando um módulo LPCXpresso 1343 com um processador ARM, no qual foi programado o firmware em linguagem C para comunicação USB com o computador e a aplicação e amostragem dos sinais digitais definidos pelo usuário em 16 canais que podem estar nas seguintes configurações: 8 entradas/8 saídas, 4 entradas/12 saídas, 12 entradas/4 saídas, 16 entradas e 16 saídas. O protótipo possui conta com 4 KB reservados para armazenamento de dados para testes do circuitos e taxa máxima de amostragem de 1 MS/s. O segundo módulo, que abrange o software desenvolvido para a estação base, foi programado em JAVA, possibilitando a comunicação com o protótipo e a interface com o usuário, permitindo a definição dos sinais digitais de entrada a serem aplicados e visualização dos sinais de saída resultantes dos dados amostrados pela mesa digital. O resultado tecnológico consistiu no desenvolvimento de um protótipo de mesa digital que, ao invés de chaves on/off e leds, utiliza uma interface com um computador. O resultado socioeconômico do projeto se revela na composição de um protótipo de custo abaixo de 300 reais, 70% inferior aos 1000 reais referentes ao valor médio das mesas digitais no Brasil, o que pode facilitar a compra deste equipamento por instituições de educação ou mesmo pelos alunos que busquem a composição de laboratórios em suas residências. 5000-01-01 2020-11-11T13:41:53Z 2013-10-08 bachelorThesis LANES JUNIOR, Edmar Anderson.
