It uses the Arduino MIDIUSB\nlibrary by Gary Grewal which simplifies the software installation.\n\nminiuntz has been tested on the SparkFun Pro Micro 5V which has the same\nprocessor (32u4) as the Leonardo. The Adafruit Itsy Bitsy 5V also has a 32u4\nprocessor so it should also work.\n\n|Trellis  |Pro Micro|\n|-------  |---------|\n|5V       |RAW|\n|GND      |GND|\n|SDA      |2|\n|SCL      |3|\n|INT      |not connected|\n\nminiuntz has been tested on the Adafruit Trinket M0 with bidirectional logic\nlevel changer.  Analog inputs are not tested. But the Trinket M0 should have 3\ninputs for analog input, if desired.  This should also work with the Itsy Bitsy\nM0, Feather M0, SparkFun SAMD21, and Arduino Zero. All use 3.3V logic levels so\na logic level converter is used.\n\n|Trellis     |LLCONV      |Trinket M0|\n|-------     |------      |----------|\n|            |     LV     |3.3|\n|5V          |HV          |USB|\n|GND         |GND-GND     |GND|\n|SCL         |HV1-LV1     |SCL|\n|SDA         |HV2-LV2     |SDA|\n|INT         |HV3-LV3     |not connected|\n\nLLCONV = bidirectional logic level converter such as Adafruit BSS138 board.\n https://www.adafruit.com/product/757\n\n![Photo of Adafruit Trinket M0 and logic level converter](https://github.com/gdsports/miniuntz/blob/master/images/trinket_m0_trellis_a.jpg)\n![Photo of back of Adafruit trellis board](https://github.com/gdsports/miniuntz/blob/master/images/trinket_m0_trellis_b.jpg)\n![Photo of Trinket M0 and mini Untztrument](https://github.com/gdsports/miniuntz/blob/master/images/trinket_m0_trellis_c.jpg)\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgdsports%2Fminiuntz","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgdsports%2Fminiuntz","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgdsports%2Fminiuntz/lists"}
