Quite some time ago, I used a free PCB coupon to get and build a Bus Pirate (3.5). I finally got around to picking up something to program it with. I have zero experience with programming microcontrollers, so my questions may be quite simple. I decided to go with the PICkit3 since, from what I could tell, it is actively supported by microchip and was available via digikey when I was purchasing capacitors for a family member's LCD monitor revival.
After some of the issues I've been encountering and researching, though, it seems that maybe I should have gone with a PICkit2 or some kind of a clone? Anyways, I built the pirate exactly with the parts list, and the pickit recognizes the chip and everything when plugged into the ICSP header...but when I try to import the bootloader hex via the IPE, it just sits there and thinks for a LONG time and basically does nothing. Any suggestions or ideas? Any additional information I should provide?
The issue I'm having, though, is that it won't recognize on any of the computers that I've connected it to. I've done continuity testing on all the pads, so it seems that all of the tracing is fine, which I would also assume means that my joints are all good. When testing voltage, though, I don't get the 3.3v that seems to be expected on pin 14. I'm at a bit of a loss here...not sure where the issue is that is keeping this from running right.
Okay, I'm working on getting together the parts for doing my Free PCB build for the USB IR Toy v1.1. My best guess based on tracing and pad placement/orientation is that this is a Rev 1 board. I'm fairly certain that I've got all the components, but I'm down to the LED for TX and R4 parts. For the LED I chose this. Based on availability of the 0805 resistor values at mouser, I assume that I would need to put 4 10Ohm, 1/4W resistors in parallel or 4 ~156Ohm, 1/4W resistors in a series? Am I missing something here, or is this one just that tricky? Any tips on how to properly carry this out? The only picture of this particular revision I can find only shows a single resistor on the PCB...
