Microduino Rotary encoder controls computer

Language:	English  • 中文

Outline Project：Microduino encoder controls the computer Objective：Use the Microduino-32U4 and rotary encoder to simulate the keyboard. Press it to simulate the "Ctrl+tab", and rotate it to move the windows (up and down). Difficulty：Higt Time-consuming：3 hours Maker：Microduino Studio-PKJ Bill of Materials Microduino equipment Module Number Function Microduino-Core 1 Core module Microduino-FT232R 1 Download program Microduino-32U4 1 Simulate keyboard and core module Other equipment rotary encoder 1 Simulate the keyboard command USB cable 1 Power for core module Document Download Microduino firmware package: http://www.microduino.cc/wiki/index.php?title=%E5%AE%89%E8%A3%85Arduino_IDE_Microduino%E7%A1%AC%E4%BB%B6%E6%94%AF%E6%8C%81%E5%8C%85 Download test program： https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Advanced_Tutorial/Microduino_32u4_KEY Debug Prepare： Download Microduino frimware package, uncompress to hardware folder of IDE; Step 1：Set up system, as follows: Step 2：Open the test program, compile it and download. Step 3：After download, use the encoder to control. Program explanation Use Arduino's USB library to relize the keyboard data input. 1.Function "Keyboard.write();" means that only press key one time. Function "Keyboard.press()" means that always hold the key, to cooperate with function "Keyboard.releaseAll()" used together; 2.Input case alphanumeric directly and use single quotation to mark. For example, input character "M"："Keyboard.write(‘M’);". Input special key, you can find the key nambe in file "hardware\arduino\cores\arduino\USBAPI.h", if you want to input "enter", just like this："Keyboard.write(KEY_RETURN);". 3.Read the I/O port voltage to judge the if the encoder was pressed which use to simulate the "Ctrl+Tab". 4.Use the interrupt to judge the directory of encoder, then choose the value. We have changed the firmware, so you need download Microduino's firmware package. 5.doEncoder() use to simulate the up and down key. 6.In main function to judge if the encoder was pressed to simulate "Ctrl+Tab". Result Rotary encoder simulates the keyboard to relize the un and down key. Press the encoder to simulate the "Ctri+tab". You change the key value to finish other experiment. Pay attention issue Compile the program must use the 32U4, because only 32U4 can support USB protocol. Need download latest Microduino firmware package. Video http://i.youku.com/u/videos
