Der Logiklevel sagt aus mit welcher Spannung das Ger\u00e4t arbeitet. Die bekanntesten sind wohl 5V und 3.3V. Da man in der Praxis immer mal wieder vor dem Problem steht ein 5V Ger\u00e4t in Verbindung mit einem 3.3V Ger\u00e4t zu betreiben, m\u00f6chte ich an dieser Stelle mal den Logik-Level Konverter vorstellen. Er erlaubt die bidirectionale Kommunikation \u00fcber die Levelgrenzen hinweg und das nicht nur f\u00fcr ein Signal sondern gleich f\u00fcr vier. Dies erm\u00f6glicht es ganze Schnittstellen wie I\u00b2C und UART oder andere Anwengungen auf unterschiedlichen Logikleveln zu realisieren.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fakten\"><\/span>Facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td><strong>Description<\/strong><\/td><td><strong>Worth<\/strong><\/td><\/tr><tr><td>Signal1 3,3V<\/td><td>LV1<\/td><\/tr><tr><td>Signal2 3,3V<\/td><td>LV2<\/td><\/tr><tr><td>Masse von 3,3V<\/td><td>Ground<\/td><\/tr><tr><td>Operating voltage 3.3V<\/td><td>LV<\/td><\/tr><tr><td>Signal3 3.3V<\/td><td>LV3<\/td><\/tr><tr><td>Signal4 3.3V<\/td><td>LV4<\/td><\/tr><tr><td>Signal1 5V<\/td><td>HV1<\/td><\/tr><tr><td>Signal2 5V<\/td><td>HV2<\/td><\/tr><tr><td>Masse von 5V<\/td><td>Ground<\/td><\/tr><tr><td>Betriebsspannung 5V<\/td><td>HV<\/td><\/tr><tr><td>Signal3 5V<\/td><td>HV3<\/td><\/tr><tr><td>Signal4 5V<\/td><td>HV4<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Anwendungsbereiche\"><\/span>Areas of application<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ul>\n<li>Kommunikation zwischen 5V und 3V Microcontrollern<\/li>\n\n\n\n<li>Anschluss von 5V Sensoren an 3V Microcontrollern<\/li>\n\n\n\n<li>Anschluss von 3V Sensoren an 5V Microcontrollern<\/li>\n\n\n\n<li>...<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Ansichten\"><\/span>Views<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-2 is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.fambach.net\/en\/logik-level-konverter\/logicconverterbottom\/\"><img loading=\"lazy\" decoding=\"async\" width=\"651\" height=\"559\" data-id=\"5397\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicConverterBottom.jpg\" alt=\"Logiklevelkonverter von unten\" class=\"wp-image-5397\"\/><\/a><figcaption class=\"wp-element-caption\">Logiklevelkonverter von unten<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/www.fambach.net\/en\/logik-level-konverter\/logicconvertertop\/\"><img loading=\"lazy\" decoding=\"async\" width=\"526\" height=\"539\" data-id=\"5398\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/LogicConverterTop.jpg\" alt=\"Logiklevelkonverter von oben\" class=\"wp-image-5398\"\/><\/a><figcaption class=\"wp-element-caption\">Logiklevelkonverter von oben<\/figcaption><\/figure>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Verdrahtung<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1461\" height=\"768\" src=\"https:\/\/www.fambach.net\/wp-content\/uploads\/I2CLogicLevelConversion_bb.jpg\" alt=\"\" class=\"wp-image-5411\"\/><figcaption class=\"wp-element-caption\">Benutzung des Logikkonverters am Beispiel der I\u00b2C kommunikation zwischen ESP32 (3,3V) und Arduino Leonardo (5V)<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Probleme\"><\/span>Problems<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Funktioniert nicht<\/h3>\n\n\n\n<p>Mal die Verdrahtung \u00fcberpr\u00fcfen besondes ob von beiden Stromkreisl\u00e4ufen die Masse angeschlossen ist.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Fazit\"><\/span>Conclusion<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Unverzichtbar wenn man den Logiklevel anpassen muss.
