Spoke PoV Dongle Assembly

Post by LED_Lighting_Company »

I have just built the dongle as per the details on the site, but there seems to be a problem.

The parts list shows R1 as 47 Ohm, R2 ~ R4 1K Ohm, but the image shows R1 as 1K Ohm and R4 as 47 Ohm.
Then I check the circuit diagram and it shows all 4 resistors a 1K Ohm, which should it be?

I cannot get communication to the Spoke PoV, LEDs do not change, status bar does not show progress.

After exiting from SpokePOV.exe I get an error telling me to check SpokePOV.exe.log but it does not produce the log file.

Any help would be much appreciated.

the parts list is correct
the image is incorrect (R1 and R4 are swapped)
and the schematic is old, so its probably mistaken alos
regardless, the parts list IS correct

Any ideas for no comms?
No shorts, open CCT's found, all orientations are correct.
Followed the instruction to the letter but still nothing.

Using XP home, Pro did not run .exe correctly,
IRQ range 0378-037F for port.

Any ideas regarding checking error log file that does not exist?

Ok, finally got the comms working, problem with the giveio.exe

I have downloaded and tested the images submitted by MUX http://www.ladyada.net/forums/viewtopic.php?t=687

All work a treat, the litter image is cool.

Is there any way of increasing the LED scan rate? four or six sets per bike is a bit way out.
Might have to get a second board to balance out the weight of the single board as it causes wobbles.

Once I have been able to get an image of the full display instead of just part of it, I will post them. Any tips on taking images using digitl camera?

Next I am plnning to test with 2 pin RGB leds with onboard auto colour changing.

Bye for now

one board should not cause wobbling on a reasonable bike. the wheel itself is pretty damn heavy.
the scan rate is set by the wheel spin rate..so just bike faster :)
