Missing the SLEEP function for URC-7562 Extender.

[Lasse]

Hello all I have a URC-7562 with Extender. The problem is that the
Extender don't support the original remotes SLEEP function.

To solve this I'm trying to create a protocol who could behave like
a delay of aprox 15 minutes to use in a macro. The delay is working
fine but I need a function call to check if any button is pressed to
be able to interrupt the delay.

I will also be greatful if some one could give the code to flash
the "HOME_THEATER" button instead of the traditional buttons.

A list with all the useful ROM subroutines should also be nice.

Most of the critical ROM calls are actually in the extender .asm file so you may be able to dig more out of there. To list all the ROM calls would be massive.

The following is how to test for a key pressed.

Code: Select all

WaitKey:	IDLE		            ; wait for interrupt
           TM	R89,#$A0	      ; was a key pressed or did a timer expire?
           JREQ WaitKey          ; no, repeat
           DI
           TM R89, #$80          ;test to see if a key was pressed
           JRNE KeyPressed       ; yes

OK Thanks,
I will test the Interupt sequence but I need to add a timer to don't get stuck waiting for the interupt!

Hi Nils,
I have tested a lot of variants but can't get any button pressed results!

I have to add a timer if not I hang until a key is pressed.
If I don't clear the R89 Flag register at the begining of the code I just exit directly. If clear it I never get any key pressed flag?

Any suggestions?

Thanks in advance

Let me digest your code and see what I can come up with

[Lasse]

I have tested a lot of code pices so far. could it be a register conflict (Push/Pop)? Do you have any subrutins to monitor/debug the result from the ROM calls? As you se I havent take the time to learn the S3C8 CPU yet! I just start to peek and poke around.

Hi Nils,
I have figure out how to detect a "key press". The solution is to read the key scanncodes not the interrupt! The following code works fine on URC 7562 with extender.
