Months later, the cube was engineered in a new version 8x8x8 upgradable to 16x16x16 connecting 4 PCBs together.<\/p>\n Meanwhile, a new trainee Rocco Marco Guglielmi<\/strong>, always under G. Di Sirio<\/b> tutorship, began writing code for assembly tests. In few weeks they build more cubes and the newcomer writes demo code. Project name is: ChibiCube<\/b>.<\/p>\n Thanks to the advice of Luca D’Onofrio<\/b>, an ST associate Engineer, R. M. Guglielmi<\/strong> is able to develop a solid number of game light.<\/p>\n In November 2013, ST Microelectronics assigns a Scholarship to this one and A. Galano<\/b> to re-design ChibiCube that reaches version 2.0: this new one provides hooks for a showcase an adapter for connect indiscriminately the STM32F3 Discovery<\/a> and the SPC560D Discovery<\/a>. MOSFETs are replaced to manage light intensity thought a software PWM.<\/p>\n Software is re-written and released under GPL3 as S3DL<\/a>.<\/p>\n ChibiCube is based on multiplexing, that means cube horizontal planes are not driven at one time. Planes are actually refreshed at higher speed than persistence of vision. About ChibiCube is a 3D LED matrix 8x8x8 composed by monochromatic LEDs individually addressable: that means not only every single LED could be in a ON or OFF state but everyone could be set at different light intensity. Inception In December 2012, students Ciro Domenico Pagano from University of Salerno, Antonio Galano from Federico II […]<\/p>\n","protected":false},"author":3,"featured_media":2395,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[1028],"tags":[],"coauthors":[241],"class_list":["post-2146","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-chibicube","cobalt"],"views":5178,"jetpack_featured_media_url":"https:\/\/playembedded.org\/blog\/wp-content\/uploads\/2016\/04\/Introducing-ChibiCube.jpg","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/posts\/2146","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/comments?post=2146"}],"version-history":[{"count":0,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/posts\/2146\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/media\/2395"}],"wp:attachment":[{"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/media?parent=2146"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/categories?post=2146"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/tags?post=2146"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/playembedded.org\/blog\/wp-json\/wp\/v2\/coauthors?post=2146"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"ChibiCube](\"https:\/\/playembedded.org\/wp-content\/uploads\/2016\/04\/art_001_cube_v0.jpg\")

<\/a>Notes on principle of operation<\/h3>\n
\nConsidering a LED cube 8x8x8 there are 8 horizontal floors: everyone is connected as common anode; that means every LED anode on a floor is interconnected each other. Every vertical column is connected as common cathode. There are so 8 anodes and 64 cathodes and their combination (64×8) provides 512 signals to drive every single LED.<\/p>\n\n","protected":false},"excerpt":{"rendered":"
