USB HID component
Component to create and communicate using a standard HID type USB class. Compatible with simulation and USB enabled microcontroller devices PIC/dsPIC/AVR. Note that AVR is currently in Beta and may have problems with custom descriptors.

Examples
Here are some examples to get you started with USB HID communications using Flowcode.
HID Mouse
Reads a EB014 keypad and depending on the key pressed sends the appropriate movement and button clicks to control the mouse.
The speed is set by the speed variable which can range from 1 to 127.
Key breakdown: 1 = UpLeft, 2=Up, 3=UpRight, 4=Left, 6=Right, 7=DownLeft, 8=Down, 9=DownRight, *=Left Click, #=Right Click.
Reads two encoders and moves the mouse cursor based on their movement since the last operation.
A switch on pin B0 can be used to toggle the left mouse click on and off and pin B1 can be connected to an LED to show the status of the left mouse button.
The EB073 encoders board connected to PortB will allow all of this functionality.
HID Keyboard
Converts a ASCII character into a keypress that will be sent to the USB host device.
A demo string is provided which is then broken down into characters and sent to the USB host.
Here is a file showing the standard HID keyboard scan codes to help make sense of the example.
File:HID Keyboard Scan Codes.xls
With the example running if you create a text file and highlight the text file then the USB device will populate the file with data.
E.g.
HelloFromYourUSBKeyboardDevice12345
HelloFromYourUSBKeyboardDevice12345
HelloFromYourUSBKeyboardDevice12345
Currently only compatible with the following characters: 0123456789!"£$%^&*()/\*-+ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz\n\t
A complete list of keyboard scan codes can be found here under section 7 - Keyboards.

HID Descriptor Tool
This tool allows you to create your own descriptors which can then be inserted into the HID descriptor property with the custom descriptor type selected.
