JP1 Remotes

Is this possible?

Is there a set of I/R codes that can be programmed readily into a PC and then dumped to the 2116?

The ROM download cable... is it just a JTAG cable and if so, where does one find the pinout and voltage levels necessary to program JP1. And where is the code base for the various kinds of devices?

Thanks,

Yes, or you could create your own customized setup codes and upload them to your 2116. We post and share upgrades that we've made for different devices; it's possible one's already been made for each of yours. You can modify them to suit your needs/tastes if you're so inclined.

Actually we don't communicate with ROM, we do with the eeprom. Check the JP-1 Files area, interface cables. there's designs/schematics, how to's for Parallel (simplest), serial, and USB cable. The cheapest and simplest is the parallel port cable, followed by the series port, followed by the USB in terms of complecxity, number of components and cost.

Hey, I am already learning.

I found the JP1 hardware page and that looks pretty straightforward.

A few questions though;

First off, I was not clear about whether it is possible to use the I/R link on a computer, and if so, whether that is worthwhile. It sounds like the I2C link on the EEPROM is not too clumsy and once you have it put together, you have a lot of flexibility.

I am reasonably knowledgeable about uControllers and I2C.

What about program codes? Is there a table for particular devices that tells you what code instructs a device to perform a particular action.

For example; does the remote send ascii "CH_U" or some such thing to instruct the TV to channel up? Where would one get the list of codes like that for various devices?

And, if I could use the I/R link on a PC, Perhaps I could use it to read I/R codes from my controllers, associate them with instructions, and use that to feed a table (which I could share)??

Thanks for all of the feedback so far.

Thanks guys.

I am really starting to pick this up now.

I read the HW spec for converting a parallel port to I2C and that seems straightforward. I have downloaded the IR software, which appears to pull data from the remote, puts it into a EXCEL spreadsheet where I can modify it, and then downloads it to the remote.

Last night I did some programming and learning on my 2116 to get it to do things that were not in the setup code for my devices.. for example, I was unable to change video/RF modes on my APEX TV, now I can. I also played with the MACRO function a bit so that when I hit the mute button, it drops down to a quiet level rather than completely silent... I always wanted that so you can engage in conversation when a commercial is on, but don't have to watch the TV to see when the commercial is over.

I appreciate you guys putting all of this information together. Maybe at some point, I can actually contribute to the group. At this point, I am a sponge soaking up all of the effort everyone else has provided. Smile

Next steps, build the I2C cable (easy for me.. I have access to a labstock) , program my remote, and download it to a file.

One of my biggest concerns about spending the time to program the remote was that when I got done, the batteries would be worn out and I would have to re-program.

Thanks!

storage life in the eeprom is supposedto be about 100 years without batteries supplying power. I have mailed remotes overseas to people, without batteries in them and two weeks later after inserting batteries the programming was still perfect. If you install an extender, after replacing batteries you'd have to re-start the extender (2 key presses), but the basic programming wasn't altered.
