INTRODUCTION



The "sony-ir.icb" driver for Interactive C allows the Handy Board to

interpret signals from a household Sony infrared remote (or any

universal remote programmed to generate Sony codes).



The driver is compatible with both the freeware and for-sale versions

of Interactive C.





INSTALLATION



Place the file named "sony-ir.icb" into the Interactive C library

directory.





LOADING



From the Interactive C prompt, type "load sony-ir.icb" to load the

driver.





USAGE



Enable the driver by executing the function "sony_init(1);", either at

the IC prompt or within a program.



Send a signal from a Sony remote, or a universal remote programmed to

generate Sony codes, to the Handy Board.  The IR sensor is the dark

green component in the board's lower right hand corner.  Then,

retrieve the received IR signal with the function "ir_data(0)" (the

value of the argument given to ir_data does not matter, but an integer

must be provided).



Each time a value is retrieved using the ir_data() function, the

driver resets to receive another signal from the IR remote.  



If no signal has been received since the last call to ir_data(), it

returns zero.



Disable the driver with "sony_init(0);".
