General description of the device
German Project site: USB IR Remote Receiver
The USB IR Remote Receiver is based on Frank M.
IRMP -
Infrarot-Multiprotokoll-Decoder and
V-USB.
The main motivation for this project was the outdated Igor Plug remote receiver.
As Frank M. is descripting RC5 is obsolete I decided to combine Frank M.
multiprotocol receiver with V-USB to be able to receive also other protocols
through the USB port. Also newer motherboards do not always include a serial COM
port.
The device is working as low speed USB 1.1 device. As it get recognized as HID
device on Windows no special driver is needed (tested on Windows 7 x86 and WinXP
SP3).
The firmware can be easily updated if the modified bootloadHID get programed
first on the device.
The USB IR Remote Receiver has also a PowerOn function to start/shutdown the
host PC through the remote control. The first received IR code will be stored in
EEPROM.
If a received IR code equals the stored code the device will switch on a
output pin for ~250ms. (see AVR source description).
With the modified bootloaderHID it is possible to update the firmware of the
device without needing to set a jumper or to disconnect/reconnect the device.
Supported software:
DVBViewer: copy
'USB_IR_Remote_Receiver.dll' to \DVBViewer\Plugins and enable the input plugin
in the DVBViewer options
Girder: copy
'USB_IR_Remote_Receiver.dll' to \Girder\Plugins and enable the plugin in the
Girder options. Girder versions since 3.2.9 are supported
EventGhost: copy
'USB_IR_Remote_Receiver.dll' and '__init__.py' to
\EventGhost\plugins\USBIRRemoteReceiver and add the plugin in EventGhost
Native: also the 'USB_IR_Remote_Receiver.dll' can be used for
self made programs with the functions InitNative and InitPAnsiChar (see below)
Right now these IR protocols are supported by the included IRMP version from
'20.09.2011':

This packet is including a
modfied version of
bootloadHID.
The new feature of the modifed bootloader is that no jumper is needed anymore.
If the modified bootloadHID got programed on the device the firmware can be
updated by the USB_IR_Remote_Receiver.dll settings/option.
The bootloader needs 2048 bytes of boot flash.
If the bootloader is getting programmed be sure to set the right fuse bits!
(Take a look to the description below how to program the device with
PonyProg2000)
If the bootloader position in the flash will be needed to be adjusted change the
bootloader address in the AVR-Studio options:
Project -> Configuration Options -> Custom Options -> [Linker
Options]
Edit the line -Wl,--section-start=.text=0x1800 for your
device. The bootloader address for the Atmega8 is 0x1800.

Device Connected: If the device got connected to
the host the icon will change to green and the included Irmp build date will be
shown. Also the USB IR Remote Receiver firmware will be shown.
PowerOn Function Status: If the PowerOn function is enabled the icon will be
green. Use the button to enable/disable the PowerOn function. If the option
"Disable PowerOn when initialized"
is checked the PowerOn function will be automatically
disabled when the plugin get's initialized. So the IR code what is used for
PowerOn can be used on the host for a different function.
Received IR Code: Will show the last received IR code
Trained IR Code: Will show the IR code what got stored in EEPROM for PowerOn
Manage Trained IR Code:
Read Trained IR Code: Reads the IR code stored in EEPROM
Clear Trained IR Code: Will clear the actual stored IR code in
EEPROM. The next received IR code will be stored as new PowerOn IR code.
Enable IRMP Logging: If your remote will not get decoded it is possible
to enable raw IR signal logging. For this the IRMP_LOGGING have to be defined.
Minimum of Repeats: The device will debounce the remote
control. With the minimum of repeats the number of needed repeats can be
adjusted until the same IR code getting sent again to the host.
A repeat of 0 means no change to the
remote control.
Flash/Update Firmware: Will show a new dialog to update the firmware of
the device. This option is only available if firmware higher or equal 1.1 is
used or the device is in booloader modus
To log raw IR signals the AVR source have to be compiled with the option IRMP_LOGGING = 1.
If the "Enable IRMP Logging" option is enabled you will be asked for a description of the last
received IR scan. The received data will be stored in the "IRMP_Log.txt" file located in the same
folder where the DLL is located. You can use this text file with "irmp.exe" to test if it can be decoded:
Example: "irmp.exe <IRMP_Log.txt"
C:\Program Files (x86)\DVBViewer\Plugins>irmp.exe <IRMP_Log.txt

Load a valide Intel Hex file to flash/update the firmware of the device. The
file size is limited by the device flash size minus 2048 bytes bootloader size.
If the USB IR Remote Receiver firmware is running the device will be reseted at
first to bring the device in bootloader modus.
After the flashing the device will reboot again and start the new flashed
firmware.
There is no need to set the jumper or to disconnect/reconnect the device if the
modified bootloader is getting used.
USB_IR_Remote_Receiver.ini
[IRMP Protocols]
List of supported protocols of the device (depend on IRMP version).
If a new protocol is added to the device the DLL doesn't need to be
updated. Just add the new protocol in this section:
name_of_protocol=IRMP_ID
[Settings]
Default the device is opened delayed with 2000ms. This value can be
changed when adding:
StartUpDelay=desired_value_in_milliseconds
{Default 2000}
Default there is no key suppression. The received IR codes are
getting forwared as they are getting decoded and received ba the DLL.
If the host software isn't fast enougth to handle fast repeating IR
codes a timer for key suppresion can be used.
This option disallow a received IR to get sent to the host software
if a previous received IR code got sent and the key suppression is still active.
Key
Suppression=desired_value_in_milliseconds
{Default 0}
Add this value to enable a log memo in the settings dialog:
Debug=1
{Default 0}
Program the device with PonyProg2000
Download and install the latest beta version of
PonyProg2000.
Run at first the calibration:
Adjust the device:
Connect the LPT program adapter and setup the program interface for LPT.
Remember to connect also the USB-Host because the device will need +5V to
operate:
Push "Probe" to test the connection to the device:
If there are problems you may need to adjust the "PONYPROG2000.INI" located in
the installation folder of PonyProg2000.
Set the value "AutoDetectPorts=YES" to NO and enter manually the LPT port
address like "LPTPorts=3BC".
Take look to the device manager to find out your LPT address.
Open the included bootloadHID.hex file:
For the Atmega8 the code should start at address 0x1800.
Open the fuse settings and set it like below:
Push "Write" to update the fuses at the device and close this dialog.
After this use "Write All" to write the bootloadHID.hex on the device:
When it is finished disconnect the USB cable to power off the device. Disconnect
also the LPT program adapter.
Plugin in again the USB cable and the device should be recognized as "BootHID"
in Windows.
Now use the DLL settings/options to download a firmware.
USB IR Remote Receiver device installation on Windows 7 x86, just plug in the device. The driver will be installed automatically
USB IR Remote Receiver device installation on Windows XP SP3, just plug in the device. The driver will be installed automatically
Function prototypes in "USB IR Remote Receiver.dll" library:
The DLL will handle the communication between the HID
AVR device and the host.
The USB IR Remote Receiver DLL can be used directly with DVBViewer in the
'\Plugins' directory as input plugin.
The USB IR Remote Receiver DLL can be also used directly with Girder in the
'\Plugins' directory. Tested with Girder 3.2.9 (last Freeware version), 4.0.5.2
and 5.0.10.
Also it can be used for other programs to handle the device with the
functions InitNative or InitPAnsiChar.
