Does anyone know if there a product on the market that
does high resolution IR learning with output to Pronto
Hex?
I don't know that but:
Pronto Hex itself limits the resolution. If the output is Pronto Hex, you can't have better resolution than an older Pronto.
I have an old Philips Pronto, but the results are
flaky with a lot of the remotes I try. Sometimes it returns
different results, even when I press the same button twice!
It's perfectly normal to get different results for the same button. Most of the values in Pronto Hex are approximate durations. Even if the original remote sent a perfect duplicate of the same signal each time (which it probably doesn't), the phases of the clocks used to transmit and receive would vary and several of the durations should be off by one unit each time.
If your IR capture device were more accurate than an old Pronto, the resulting Pronto Hex would vary between presses of the same button more, not less than a Pronto varies.
For most IR systems, the receiver can tolerate variation in the signal far greater than those introduced by the resolution and accuracy limits of the Pronto.
Also, is there anything else out there that will do IR
learning but uses something like a USB plug?
Not sure what you mean.
There is a USB version of the JP1 cable. Several of the low cost models of JP1 capable remotes do learning. Those have slightly higher resolution and accuracy than a Pronto. With those you could learn a batch of signals to the remote then download to the PC. You couldn't do direct learning to the PC. Also the software doesn't output Pronto Hex, but the decode info it gives can be used to generate clean Pronto Hex with MakeHex.
The CaptureIR software uses a simple (cheap) IR detector connected to the printer port to capture and decode IR signals. It is also higher resolution and accuracy than learning with a Pronto and gives decode info that can be used via MakeHex to generate clean Pronto Hex.
