This project allows the user to use an inexpensive TV
style IR remote control to send commands to an Icom radio using the Icom CI-V
interface. The IR remote control must be configured for Philips RC5 remote
control signals. A windows program allows the user to add, delete
and edit the CI-V commands. There is a raw mode that allows a predefined serial
stream to be sent to any RS-232 device. The experimenter can use the supplied
firmware or develop their own firmware using the available ISP and JTAG
connectors.
| The product is an experimenter's project targeted to the amateur radio operator and
shortwave/scanner listener. |
| One open collector 2N3904 is available for remote control. |
| The command sequence corresponding to a particular remote control button
is stored in the processor's EEPROM. |
| A windows program is available which allows the user to configure the EEPROM. |
| The processor flash memory can be updated using the self-contained boot
loader and the windows
configuration program. Updated application programs will be available for
download from the web. |
| No JTAG or ISP connections are required when the demo control program is
used. The program uses the self-programming feature of the Atmel AVR. |
| The windows program also provides a hex monitor for the CI-V bus. |
| The windows program is simply copied to the PC. There is no installation.
The program does not make registry entries. |
| The configuration information in the processor's EEPROM can be
uploaded/downloaded to/from a saved configuration file. |
| The IR receiver must be 36KHz for Philips RC5 decoding. |
Please note that this project is a CI-V control system. It does not provide any
analog features such as volume control. The volume of some Icom radios can be
controlled using the CI-V bus, but most can not.
