ill probably feel stupid but i do anyway so...
here we go. Our school just got the EDU-Microchip last firday and i immediately installed all of the components onto the computer (needless to say i was in a state aptly dubed "Nerdvana"). Just today i had the time to upload the code, with a few modifications to make it 2 joystick instead of one, and put it on the CPU. Everything loaded fine. But when i brought it out to the controllers, it would say it did not have a signal. I even tried teathering it. So, to be safe, i uploaded the original code and still got nothing. I remember having to change dipswitches on our cpu last year to put our team number in, but i cannot seem to find them on the new cpu. Is the number now done through code? Anyways, to get to the point, I cannot get the cpu to pick up the signal from the contorlers. Can anybody help me?

The title of this thread pretty much says it all. I'm really sorry man but the OI and joysticks are no longer used with the EDU. It now uses a hobby R/C control system. Look at page six of this. There is also this thread and this thread

Heh, I know how you feel... it really stinks not being able to test code until January (my team can't afford to pay for some add-on controller just for the edu-bot, it's not worth the cost)

I havent looked into it yet, but I think you can write and test auton code - you just cant control it from the O/I.

make an RC to EDU battery harness
Do yourself a favor, make a harness that converts from an RC battery to the connector on the EDU board.
The RC batteries have more capacity, are cheaper, have better/cheap chargers and all around are just worth the bother. I have done it for our EDU robot and I would never go back to the IFI provided set up. Joe J. |

If you don't mind sacrificing a few of the 16 ios, you can connect potentiometers to the analog inputs on the EDU-RC. If you read these in the User_routines.c loop, they will update at the same rate as the radio would.
The Wiring does not seem to match a standard joystick pinout however. I believe that this could be fixed by switching the powers and the grounds on the joystick connector (I think the analog inputs are internally pulled up on the Edu-RC). Potentiometers work fine on the anolog pins. |
