Support Forum » LED Kit - Columns Backwards
May 29, 2011 by frankdwest |
Feeling stupid, but... I got confused on the directions despite their being very clear, and wired column 0 on the RIGHT hand side from the front (anodes). Is there a straightforward way this can be corrected in the software/wiring, or is this error require major surgery to correct (and thus probably beyond my current capabilities). If major surgery, can I purchase just the bag of LED's so I can do it correctly the second time ? |

I ordered 120 new LED's from digikey. I think the code will need some in depth reconfiguring. Better to try again and do it right :-) |

Sorry frankdwest, but you are not the first to do that :-) I think if you search the forum you will find code to correct column 0 on the right. You might have to read a lot of threads but that is your punishment. Ralph |

So...I think I can rotate the board 180 degrees. That puts Column 0 on the left from the front. However, it leaves the diodes all reversed from the original design. Looking at past forum posts I think I can make a correction in this code block:
In the function ledarray_set_columndriver the third parameter is either 1 or 0 for source or sink. Swapping those in the above code should allow the test code to work with my wrongly wired LED panel. (?) I am going to try this and see... Frank |

I ended up doing the same thing as you (at least I think by your description. My old post is here, where others helped me get it working. If you still can't get it working, let me know, I can post my full working code. |
