USB Infrared Toy / Re: Irtoy Lirc (Linux) driver
This is amazing - i've been waiting a while for a native LIRC driver for the toy :)  You rock!

The patch seems to work fine. ¿Do you know if the LIRC developers plan to merge it into the mainline?

USB Infrared Toy / Re: Homemade PCB, no VUSB
Ian, who is oficially the coolest guy in the world now, kindly sent me a QSE159 which i had some difficulties to locate. Thanks!

I can confirm that the device self-tests perfectly. And here it is, ready to be installed on my HTPC...

USB Infrared Toy / Re: IR Toy 1/2 with OpenWRT
[quote author="testor"]Thanks for your reply.
Does it mean that it is currently not possible to transmit ir codes with the IR Toy using LIRC but only to receive them?[/quote]

Sadly, yes. WinLIRC does support the USB IR Toy in its "native" mode but this hasn't been backported to LIRC as far as i know.

[quote author="ian"]Also remember to use a diode in series on the MCLR line of the JDM2 - it puts 13volts on MCLR and the 18FX550 can take max 12.6 or 12volts or something.[/quote]

12.5v max, IIRC. To be honest i never cared about it, as it seems that both the 18Fx series can be programmed at 13v and the 16Fx series can be programmed at 12v in my experience. Still, yes, it's out of spec.

[quote author="erdabyz"][quote author="LisandroP"]I don't know what the hell happens to the 18FX550 series. I myself have broken like 5 4550's in TQFP44 in 3 different proyects in less than three months. With broken I mean that they were working, and suddenly they stopped. After checking the memory contents, the first 8 to 16 (or so) words were erased. It's magic. Some of them re-worked after reprogramming, some never started the oscillator again (literally). I first thought it was a USB ESD issue, but nopes. I also thought it could be something related to the "popcorn effect" while soldering, but nopes, I added some serious ESD protection. A """pre-baked""" chip also broke. I also had one that woudn't properly read the state of a pin, and guess what, worked after reheating. And poofed after a month.

Yeah, for me it also was the first time I saw a broken pic. In my early years I did all sorts of mistreat to those poor first PIC's that came to my hands, and all of them still work. I've only experienced that issues with FX550's, but never with any other PIC model, even with USB.[/quote][/quote]

I keep hearing about all sort of strange issues with the 18F series. For example, i usually program my PICs with an old trusty JDM2 i built a long time ago. This device has programmed every single PIC i used without issues... except for the 18F2550/4550, where it requires a filter adaptor for the PGC/PGD lines (nothing more than 100Ohms and 27pF in series to ground). And this is regardless of the connector length. In fact, i hear people had issues using the PICKit2 with these devices.

In my experience, PICs are way more rugged than they should be. I've had PICs with overvoltage, reverse polarity, sinking several times the maximum rated current or incorrectly wired and they always seem to survive without a hitch. I've recently had a 3,3v receiving 13v on some GPIO pins! So, when something breaks with a PIC design the device itself its usually the last thing i check.

Thanks for the heating tip BTW. I'll try it tomorrow... i've seen stranger stuff happen :)

General discussion / Re: Microchip Arduino thing interview questions?
[quote author="tcmichals"]Also it would be nice to take the PICkit3 and add it to openocd.  Then you have a complete open source solution.[/quote]

IIRC the PICkit3 schematic has been available for a while now in its official user guide. Couldn't find any information on how it is licensed though...

General discussion / Re: Microchip Arduino thing interview questions?
The powerful MCU in the chipKit is very welcome, ¿but Is Microchip working today, in any fashion, with the Arduino crew to unify efforts, or is this only a ploy not to be left outside all the action?

¿Do we have documentation on known incompatibilities with existing Arduino shields?

I'm also worried about the licenses used and the lack of open source tools for the device.

USB Infrared Toy / Re: ¿Support for other protocols than RC5 / RC6?
¿Could that be done with LIRC (the regular Linux service)? AFAIK, LIRC/WinLIRC only understands commands sent by the USB IR Toy on irman mode, which only works with RC5 and 6. Switching the device to sample mode shows the raw decoder output just fine, but i don't think LIRC understands it.

USB Infrared Toy / ¿Support for other protocols than RC5 / RC6?
I was just wondering, ¿is it planned to add support for RC protocols (Sony, RCA, RC-MM et all) other than RC5/6 on Irman mode? This would be a blast; Irman even returns enough bits to identify which protocol is being used on each decoded message.

I'm just asking because i have about 7 remotes from different sources on my home, and only two of them seem to be identified by the USB IR Toy, which is a shame. Reviewing the code i reckon this would require some rework for sure...

[quote author="ian"]Post it up, whatever the format, as long as you're ok with an open license. If it isn't based on our files (cc BY-SA), please specifically state the license you want so I can include a note with the files.[/quote]

Creative Commons is fine. Attached is a rar with PCB, schematics, netlist files and images for both the regular design and the one with the breakout area, in case someone finds it interesting.

EDIT: I've found out a typo in the schematics (the emitter resistor for the IR Leds' CCS was incorrectly labeled 6k8 instead or 6R8). The attached files are now corrected. Sorry!

USB Infrared Toy / Re: Feature requests
[quote author="anego"]adding support for others remote codes : RC5, RC6, NEC, SONY SIRC, Matsushita panasonic, etc
in uir/irman mode![/quote]

Agreed. This must happen!
