| [How To] Create a own USB HID device |
 Posted: Sun Dec 30, 2012 8:12 am |

Hello Community,
A few days ago I started to create my own USB device.
I also saw that much guys tried that also, maybe they got it working or not and because of this I want to release my C# and my PIC Project.
The C# program is not fully made by me, but I edited it and even got it working for my device.
The most important things in the PIC firmware:
Commands:
| Code: | //Commands
#define CMD_LED2_ON 0x80
#define CMD_STATE_LED2_ON 0x81 |
Check the incoming data for the Commands:
| Code: | //Get the Data
usb_get_packet(1,in_data,16);
//Write to the LCD that Data has been received
printf(lcd_putc,"\fReceived Data:\n");
//Check if the incoming byte equals the Command
if(in_data[0] == CMD_STATE_LED2_ON)
{
//Write to the LCD that command 0x81 has been executed
printf(lcd_putc,"LED2 is: %d", input(LED2));
//Check if LED is high
if(input(LED2))
{
//Set the output byte to 0x01 == true
out_data[0] = 0x01;
//Send data
usb_put_packet(1,out_data,16 USB_DTS_TOGGLE);
output_high(LED2);
}
else
{
//set the output byte to 0x00 == false
out_data[0] = 0x00;
//Send data
usb_put_packet(1,out_data,16 USB_DTS_TOGGLE);
}
}
else if(in_data[0] == CMD_LED2_ON)
{
//Toggle LED State
printf(lcd_putc,"Turn LED2 ON");
output_toggle(LED2);
}
|
The most important things in the C# Project
Execute a command:
| Code: | | public void RunCommand(Byte be) |
PID and VID:
| Code: | Int32 myProductID = Convert.ToInt32(0x0042);
Int32 myVendorID = Convert.ToInt32(0x04D8); |
Get data from the PIC for example: Read the LED state:
| Code: | if (!hidHandle.IsInvalid)
{
ReadCommand(0x81);
//Read the LED state
bool ledState = Convert.ToBoolean(m_Result);
if (ledState == true) this.ledStateLabel.Text = "LED is on";
else this.ledStateLabel.Text = "LED is off";
}

I hope it helps to understand it and getting it working for you too and I hope that someone moderator will make it sticky.

you are right I'm the one who is having a lot of difficulty starting on usb hid devices
I have started in visual c# 2008 last year, and now c# 2010. I've already made many C# projects
communication with PIC4550,2550 usb->PC, but using C# serial Port, I wanna do it using HID.
But As the guy said "THE LINKS ARE BROKEN". Could you please send me it by email:
ze.vana@hotmail.com , I have an account in www.4shared.com, if you have too, you can put the your links there. |

Note: CCS defaults to software i2c, unless you use the
hardware i2c pins and add the FORCE_HW parameter to the #use i2c()
statement.
