![]() Code example: /* Pro Micro Test Code by: Nathan Seidle modified by: Jim Lindblom SparkFun Electronics date: January 20, 2012 license: Public Domain - please use this code however you'd like. ![]() ![]() One that communicates with the computer through USB to the serial monitor (the serial monitor in the Arduino software) and one that communicates through hardware pins in the board. (need account to the forums to see the files) fm did me a great favor and look with me at the result, so here are the edited files. I have integrated the PCINT and Interrupt (attachinterrupt, detachinterrupt) functionality in the files from the IDE. I used the vinciDuino in the Arduino IDE 1.0, the original Leonardo isn’t in stock, the IDE didn’t support the Board completly (it’s not nessesary at this piont). This tutorial covers the Arduino “Leonardo” platform which uses the new USB-enabled ATmega 32U4 MCU, with a very powerful bootloader environment that emulates both a USB mouse and keyboard (standard HID devices, no drivers needed), as well as a virtual COM port!Īs of Arduino 1.0, interrupts are not supported on the Arduino Leonardo…Long story short, I ended up copying the macros for interrupt bitmasks/registers from the Teensyduino project, which has a mega32u4 target board. Instead you must use Pin10 as shown in the connection diagramĪrduino®-Leonardo HID Keyboard & Mouse Tutorial and Advanced Examples For the source board, the Reset pin is not used. Note that the ICSP header perfectly matches the wiring for the destination board (because it assumes you will use an ISP programmer to program the chip). You can also use the ICSP header, which has the following pin assignments: Now you have the programmer ready to burn the bootloader into a destination board.Ĥ- Make the connections (bottom board is the programmer) Then compile and upload to the Arduino you are using as the programmer. Copy the sketch and paste it into a blank sketch. An earlier version required that you compile with Arduino 022, but this version compiles with Arduino 1.0. If you already see “Arduino Leonardo”, then you don’t have to do this stepģ- Get the latest version of Arduino ISP. This allows the Leonardo option to show up in the “Boards” menu. Only Arduino 1.0 has built in s/w to burn bootloaders with an Arduino board.Ģ- In Arduino-1.0/Hardware/Arduino/boards.txt, uncomment the Leonardo lines (remove the “#”). The process has been a bit complicated because of several “bugs”, but this seems the latest:ġ- Download both the latest Arduino 1.0 software. But here are some resources and compatible boards that you can use in the meantime:īurning the Leonardo bootloader with another Arduino board You can read an earlier post on the differences and advantages with the “standard” Arduino boardĪrduino IDE support for the Leonardo board is still under development. I don’t think the Arduino team popularized this microprocessor, but their implementation in the Leonardo board is making everyone coalesce around the Arduino IDE. The Arduino Leonardo is not yet available for sale, but it seems it will become the most popular board as there are many other 32U4-based implementation appearing and/or claiming compatibility with the Arduino IDE.
