S\u00e3o extremamente \u00fateis. Mas tamb\u00e9m s\u00e3o extremamente caros. Neste tutorial, vou mostrar-lhe como fazer um oscilosc\u00f3pio barato e f\u00e1cil com um Raspberry Pi Pico.<\/p>\n\n\n\n<p>Este oscilosc\u00f3pio - a que chamo \"Picoscilosc\u00f3pio\" - gira em torno de um Pico e da aplica\u00e7\u00e3o Scoppy num dispositivo Android. Pode ser utilizado para detetar e analisar sinais de baixa tens\u00e3o.<\/p>\n\n\n\n<p>Por isso, aqui, vou mostrar-vos como montar um oscilosc\u00f3pio super barato usando um Raspberry Pi Pico W e uma Scoppy em 5 passos simples.<\/p>\n\n\n\n<p>Vou fazer isto com um smartphone, mas tamb\u00e9m o pode fazer com um tablet. Desde que tenha o Android 6.0 ou mais recente, est\u00e1 tudo pronto.<\/p>\n\n\n\n<p><strong>AVISO<\/strong>: A eletricidade \u00e9 perigosa. Por favor, tenha cuidado e certifique-se de que n\u00e3o utiliza o oscilosc\u00f3pio de uma forma que o possa prejudicar a si ou a outros. Este oscilosc\u00f3pio Pico s\u00f3 funciona com sinais de baixa tens\u00e3o e baixa frequ\u00eancia e s\u00f3 deve ser utilizado nesses casos.<\/p>\n\n\n\n<p>Esta configura\u00e7\u00e3o do oscilosc\u00f3pio foi concebida para detetar tens\u00f5es inferiores a 3,3V. Se quiser ir mais longe, pode descobrir mais <a href=\"https:\/\/github.com\/fhdm-dev\/scoppy\">aqui<\/a>. Mas aqui, n\u00e3o estaremos a brincar com nada que chegue a isso.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">O que \u00e9 necess\u00e1rio<\/h2>\n\n\n\n<p>Estou a utilizar alguns componentes aqui:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Um Raspberry Pi Pico W<\/li>\n\n\n\n<li>Um smartphone Android<\/li>\n\n\n\n<li>Uma placa de ensaio<\/li>\n\n\n\n<li>Alguns cabos de liga\u00e7\u00e3o macho<\/li>\n\n\n\n<li>Um cabo USB-para-micro-USB capaz de transferir dados<\/li>\n\n\n\n<li>Um adaptador USB-OTG<\/li>\n<\/ul>\n\n\n\n<p>A s\u00e9rio, todos voc\u00eas <em>necessidade<\/em> \u00e9 um Pico, um dispositivo Android, o cabo USB e o adaptador USB-OTG para configurar tudo.

Certifique-se de que est\u00e1 a utilizar um cabo USB que pode transferir dados. Se n\u00e3o for poss\u00edvel, n\u00e3o acontecer\u00e1 nada.<\/p>\n\n\n\n<p>Desde que esteja a utilizar o cabo correto, pode ent\u00e3o soltar o bot\u00e3o BOOTSEL e aparecer\u00e1 uma nova pasta: RPI-RP2. Dever\u00e1 tamb\u00e9m ver o LED do seu Pico a piscar.<\/p>\n\n\n\n<p>Mova o ficheiro .uf2 para a pasta RPI-RP2 e este ser\u00e1 automaticamente ejectado ap\u00f3s a transfer\u00eancia do ficheiro.<\/p>\n\n\n\n<p>Agora o seu Pico est\u00e1 pronto a funcionar.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Passo 2: Descarregar o Scoppy no seu Android<\/h2>\n\n\n\n<p>O Scoppy \u00e9 uma aplica\u00e7\u00e3o gratuita que pode ser descarregada diretamente da Google Play Store. Tamb\u00e9m \u00e9 poss\u00edvel atualizar para o Scoppy Premium, que tem um custo \u00fanico de 2,29 euros no momento da reda\u00e7\u00e3o deste artigo.<\/p>\n\n\n\n<p><\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"461\" height=\"1024\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/scoppy-461x1024.jpg\" alt=\"Descarregar a aplica\u00e7\u00e3o Scoppy\" class=\"wp-image-6209\" style=\"width:156px;height:auto\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/scoppy-461x1024.jpg 461w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/scoppy-135x300.jpg 135w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/scoppy-5x12.jpg 5w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/11\/scoppy.jpg 576w\" sizes=\"auto, (max-width: 461px) 100vw, 461px\" \/><\/figure>\n<\/div>\n\n\n<p><\/p>\n\n\n\n<p>Penso que a vers\u00e3o gratuita \u00e9 suficientemente boa para muitos objectivos, mas a vers\u00e3o paga oferece funcionalidades adicionais.
