JP1 Remotes

Hi Rob,

I am using an extender.

I had to remove my old TV and DVR and their protocols, and add the new ones to test them to see if they worked.

I used to have my receiver switch modes to select what was being watched/listened to, but since my receiver has no hdmi, I am using the TV as the input ...

Hi,

Thanks for the help everyone. It took me 3 hours tonight to get all the changes I needed to get done completed, but everything works beautifully now and I changed a lot. My little $40 remote from Radio Shack is still kicking along and getting the job done!!

Thanks,

Alan

Hi,

Thanks guys, I appreciate it. Will check it out!

Hi,

Not yet. I'm using an extender on it. I was hoping to find a KM so I could choose which keys map to which keys... How do you think I should proceed?

Thanks for your help,

Alan

Hi The Robman,

Thanks for the links, they worked great for me! Remote is programmed and working great with the new DVD.

Have a great day!

Hi,

I have a radio shack 15-2116 8 in one remote. Back about 6 years ago I used IR.EXE to program it. I think I am using an extender but don't recall for sure.

I had it programmed for Toshiba DVD, but it died and I switched to a Sony DVP-NS710H.

I loaded IR and opened my config file 2116ex2.IR ...

Yes, thats it! Thanks, I didn't realize I could do that!!!

Have a great day,

Alan

While it probably doesn't make much difference when it runs (although it would make a little!), is there a way I can move these item up or down within their list to organize them? For example, if keymove #39 would be better up at #10, is there a way to move it around?

Thanks,

Alan

Rom protocols execute directly in rom. They are not copied to ram. The extender doesn't know whether a protocol comes from rom or eeprom, so it must create a stack frame to reload itself after any protocol, even rom protocols where the extender would still be there without reload.

That might ...

On a human time scale, multiple loads of 255 bytes from eeprom to ram add up to very little. I haven't done all the computations necessary to know exactly how long it takes.

Too bad, I was hoping this might be the reason for the slowness since a previous poster mentioned is eeprom comm was done ...

The eeprom isn't mapped into the address space at all and it is impossible to execute code in the eeprom.

The remote can read an write the eeprom by a slow serial protocol, but can't directly address it.

The only way to use eeprom contents is to first copy them to either ram or registers.

That ...

Hi guys,

Can you help me understand how the extender works and how the remote's memory map is mapped? The asm file when compiled puts the eemain and ee_part2 at 0x0752 and 0x03a. Does the part 1 and part 2 get copied to 0xff00 and execute there? Why doesn't it execute in eeprom? Is the eeprom ...
