PR26 (Build Failed)

[Innovative]

Yeah! Got it and USB keyboard functioning well now... thank you!! thank you!!
BTW, I have another idea to do a combo with USB Keyboard + mouse click + output for LED, do you have any idea we can combine the different device in the USB_descriptor and how to use it?

Thanks!

Can. But you need to modify the HID Descriptor part in usb_descriptors.c and usb_config.h. I haven't try it yet but I found a site about the multiple HID devices in one, http://frank.circleofcurrent.com/cache/ ... rial_1.htm To create your own HID Descriptor, you can use this tool, http://www.usb.org/developers/hidpage#HID Descriptor Tool, click "HID Descriptor Tool" to download.

I got the mouse + Keyboard by using PIC18F2550 it working well. However, i would like to change it become HID output Keyboard. I have change the descriptor to HID output + Keyboard as below but when i plug in it shown yellow bang in the device list.
BtW, do you know how to configure the VID and PID? for the working mouse + keyboard if i change the VID / PID then the device will not be working anymore.
Please let me how is the code if you already success to build the HID output + Keyboard, feel that it is usefull.

Did you change this "HID_RPT01_SIZE" value in usb_config.h? HID_RPT01_SIZE is the size of your USB descriptor (located at usb_descriptors.c). One byte counted as one. For example, (0x09, 0x06, 0xA1, 0x01), the size is 4. You need to count it start from /* Usage (Keyboard) */ to /* End Collection,End Collection */

/* HID */
#define HID_INTF_ID 0x00
#define HID_EP 1
#define HID_INT_OUT_EP_SIZE 1
#define HID_INT_IN_EP_SIZE 8
#define HID_NUM_OF_DSC 1
#define HID_RPT01_SIZE 63
#define USER_SET_REPORT_HANDLER USBHIDCBSetReportHandler


I think we don't need to specify the VID/PID. May be you can try to change both of it.

[Innovative]

Ya, I have change it accordingly but it still shown the yellow bang.
BTW, if I try to change the PID and VID also will get the error yellow bang, do you have any idea how to configure the PID and VID?

Thank you!!

As I know, the VID/PID is just for PC recognize whether this device has been installed before or not.

How about you remain VID = 0x04D8 (Microchip VID), and change PID.
