[quote author="ian"]Awesome build, thanks for posting! I'll blog it up.
Do you plan to publish the PCB files? If it's open source I'll include it in the SVN and release packages.[/quote]
Sure, be my guest! :) I've designed the board using PCB and gSchem. If that's good for you i'll review the designs to clean them up in order to get them ready for publishing.
I also have a PCB design with the pin breakout area, which i didn't quite like because it's more crowded and leaves little copper to connect the "ground plane" areas on the board. It's the same design and schematic though so it should work just fine.
[quote author="schazamp"]That sounds interesting. Though I'm afraid I can't help much with the issues you're having, I'd like to see your project. Do you have any photos you can post?[/quote]
Sure, no problem - i'll snap some pictures as soon as i get home today.
EDIT: Here you go - sorry about the lousy quality :) Notice that there's no QSE159 as i haven't been able to locate that part locally yet.
Hello. I've recently built a single-sided, through-hole version of the USB IR Toy v2, using the schematic posted on the wiki for it without the pin breakout area.
Now, i can program this device just fine through ICSP using the .hex files provided in the package, but the thing is VUSB never raises to 3,3v (floats arround 0,6v) with any of them, so the device never ennumerates. I can confirm the device works flawlessly otherwise (the bootloader alone responds correctly to shorting PGC/PGD after a reset, for example).
Right now my VUSB pin is connected to ground via a .47 uF cap, but i've tried several values without making any difference
¿Could it be possible that some configuration bits need to be set up manually? I've checked the design so many times i'm positive that it is correct. Is either that or a dud 18F2550 with a broken internal regulator, but i've never seen such a thing happen in the past. I've used a JDM-type programmer with both WinPic800 and piklab-prog, with identical results.
Thanks in advance!
PS: If anyone is interested in a single-sided PCB for the IR toy just let me know. Mine is 40x50mm using an USB-A connector and includes a USB pin header, VCC/GND/RX/TX header for serial communications and ICSP - had to dispense with the pin breakout area though.
