Euclidische ritmes - verwijzend naar de oude Griekse wiskundige Euclides - zijn ritmes met supergebalanceerde patronen over tijdsintervallen. <\/p>\n\n\n\n<p>Dit heeft allerlei echt coole implicaties, maar voor dit drummachineproject betekent het in feite dat je de intervallen bepaalt en hoeveel beats er in elk interval moeten.<\/p>\n\n\n\n<p>Dus euclidische drummachines baseren hun patronen op <a href=\"http:\/\/cgm.cs.mcgill.ca\/~godfried\/publications\/banff.pdf\">euclidische ritmes<\/a>die je kunt zien in deze video die aproximacion, <a href=\"https:\/\/github.com\/redraw\/euclid-16\">die gaat door redraw op GitHub<\/a>, ge\u00fcpload:<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<figure class=\"wp-block-video aligncenter\"><video src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/euclid.mp4\" controls=\"controls\" width=\"467\" height=\"467\"><\/video>\n<figcaption class=\"wp-element-caption\">Krediet: <a href=\"https:\/\/github.com\/redraw\/euclid-16\">hertekenen<\/a>.<\/figcaption>\n<\/figure>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\">Hardware<\/h2>\n\n\n\n<p>Zoals je kunt zien, heeft dit project een perfboard bevestigd aan een zeepkoker, samen met een <a href=\"https:\/\/buyzero.de\/products\/rgb-encoder-breakout?_pos=1&amp;_sid=b966f7d8f&amp;_ss=r\">encoder<\/a>, <a href=\"https:\/\/buyzero.de\/products\/leds-widerstande-basic-maker-kit?_pos=20&amp;_sid=5c3c55dc3&amp;_ss=r\">een gele LED samen met 16 rode LED's<\/a>vier <a href=\"https:\/\/buyzero.de\/products\/micro-taster?_pos=2&amp;_sid=386f64131&amp;_ss=r\">knoppen<\/a>twee schuifregister 74HC595 <a href=\"https:\/\/buyzero.de\/products\/mcp23017-i2c-16-eingang-ausgang-erweiterungs-chip\">IC's<\/a>en een <a href=\"https:\/\/buyzero.de\/products\/raspberry-pi-pico-w-h-konfigurator-pico-pico-w-pico-h-pico-wh\">Raspberry Pi Pico<\/a>.<\/p>\n\n\n\n<p>Uiteraard is de opstelling hier vrij aanpasbaar. Elke behuizing die bijvoorbeeld de Pico en de benodigde componenten kan bevatten, zou goed geschikt zijn voor een project als dit.<\/p>\n\n\n\n<p>De twee schuifregisters besturen de 16 LEDs, zoals aangegeven in het bedradingsschema in de GitHub repository:<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/Screenshot-from-2023-08-07-09-33-22-1.png\" alt=\"\" class=\"wp-image-4625\" style=\"width:624px;height:412px\" width=\"624\" height=\"412\" srcset=\"https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/Screenshot-from-2023-08-07-09-33-22-1.png 920w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/Screenshot-from-2023-08-07-09-33-22-1-300x198.png 300w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/Screenshot-from-2023-08-07-09-33-22-1-768x508.png 768w, https:\/\/picockpit.com\/raspberry-pi\/wp-content\/uploads\/2023\/08\/Screenshot-from-2023-08-07-09-33-22-1-18x12.png 18w\" sizes=\"auto, (max-width: 624px) 100vw, 624px\" \/><figcaption class=\"wp-element-caption\">Krediet: <a href=\"https:\/\/github.com\/redraw\/euclid-16\/tree\/main\/wiring\">hertekenen<\/a>.<\/figcaption><\/figure>\n<\/div>\n\n\n<h2 class=\"wp-block-heading\">Software<\/h2>\n\n\n\n<p>De code is CircuitPython, wat aproximacion opmerkt op de GitHub, \"geweldig is om mee te spelen,\" maar \"het biedt geen hardware timer interrupts, wat cruciaal is om het tempo consistent te houden.\"<\/p>\n\n\n\n<p>De audio wordt uitgevoerd via PWM, maar kan ook via I2S worden uitgevoerd. Je kunt meer te weten komen over audio-uitvoer met de Pico en PWM, I2S en I2C in <a href=\"https:\/\/picockpit.com\/raspberry-pi\/everything-about-sound-output-using-the-pico-w\/\">ons artikel over audio met de Pico W.<\/a><\/p>\n\n\n\n<p>In de reddit post zegt aproximacion: \"Op dit moment werkt het als een MIDI sequencer, maar audio via PWM, of met behulp van een i2s DAC zou ook mogelijk moeten zijn. Het ideale doel zou zijn om er goedkope DR-55, CR-78, Minipops, etc samples in af te spelen.\"<\/p>\n\n\n\n<p>En deze kleine drummachine kan tot 16 sequenties opslaan.<\/p>\n\n\n\n<p>Dus als je een supergoedkope, echt krachtige euclidische drummachine wilt maken met je Raspberry Pi Pico, dan is dit het project voor jou!<\/p>\n\n\n\n<p>Pak een paar Pico's en dan kun je dit samenstellen met <a href=\"https:\/\/diyelectromusic.wordpress.com\/2021\/01\/23\/midi-micropython-and-the-raspberry-pi-pico\/\">enkele andere projecten<\/a> om je rockband of een volledig orkest op te zetten. <\/p>\n\n\n\n<p>Als je meer details wilt zien, bekijk dan de GitHub broncode <a href=\"https:\/\/github.com\/redraw\/euclid-16\">hier.<\/a><\/p>\n\n\n\n<p>Als je meer Paragon-projecten wilt zien die we in deze serie hebben behandeld, klik dan op <a href=\"https:\/\/picockpit.com\/raspberry-pi\/category\/raspberry-pi-projects\/paragon-project\/\">hier<\/a>.<\/p>\n\n\n\n<p>En als je vragen hebt of een project voor deze serie wilt voorstellen, reageer dan hieronder!<\/p>\n<div class=\"shariff shariff-align-center shariff-widget-align-left shariff-buttonstretch\"><ul class=\"shariff-buttons theme-white orientation-horizontal buttonsize-medium\"><li class=\"shariff-button twitter shariff-nocustomcolor\" style=\"background-color:#595959\"><a href=\"https:\/\/twitter.com\/share?url=https%3A%2F%2Fpicockpit.com%2Fraspberry-pi%2Fnl%2Fparagon-project-euclidische-trommelmachine%2F&text=Paragon%20Project%3A%20Euclidean%20Drum%20Machine\" title=\"Delen op X\" aria-label=\"Delen op X\" role=\"button\" rel=\"noopener nofollow\" class=\"shariff-link\" style=\";
