Pic programing problems

[Dave Burrows]

I've been trying to program a new starting address for 1 of my REN64XC, with a start add of 8 (i have watched all the Wayne J videos and read all the Start add guide). After getting the pickit3 to operate and program the chip, i place it on the board and the LED for channel 1 lights up.
Now thinking i got the start address wrong, i have tried to program it back to standard and channel 1 lights up again,
Is there something obvious that i'm missing here?

Thanks

Dave

If you are using the regular firmware(not the DMX) the pics don't need an address. Each pic strips off it's 8 channels and sends the rest to the next pic in line.

Channel 1 lit up usually indicates a blank PIC so it doesn't sound like the programming worked.

A good test would be to take a PIC you didn't mess with and move it to the First IC Socket. When you are programming make sure you Verify. I just get in the habit of doing both.

[Dave Burrows]

Thanks for the quick replys. I'm at work now so i'll try reprogramming tonight.
The start add of 8 is for the second ren 64 that i'm daisy chaining, and yes tried another known good pic and all was well.

Thanks again

Just as a clarification, as long as you are not running the DMX firmware you don't need to do anything different for the 2nd ren 64 pics. It will receive the Renard stream directly from the 1st Ren 64 and no addressing is involved.

Sorry no i am not running dmx firmware

I have tried that but it duplicates the origanal 64 channels on the second board. Thats why i thought i needed the starting address of 8 for the second ren 64 that has been daisy chained.

I must be missing something - - why do you say '8'? Is this for the new "Start Address" Renard firmware or just the regular code. If you are using regular code and both Ren64's are daisy-chained, you should not change the starting address at all and leave them all at a starting address of '1' for ALL PICs (all 16 of them!) on both boards. In Vixen you just need a single Renard plug-in set for 128 channels.

I tried that in vixen and it still duplicated the first 64 channels to the second board. Ren 1 channels set to 1-64 ren 2 channels set to 65-128, but when i run the sequence both ren 1 and ren 2 only recieve channels 1-64.

So from what i gather here, i don't need to change the start address for the second ren...and i'm barking up the wrong tree with changing start addresses and should be looking at the set up in vixen?

Thanks

Dave

O.k. i have gone back to basics and looked at the REN XC page and may have found that i am barking up the wrong tree. I do some more testing when i get home and update than.

Thanks again to all

Correct - all PICs should be programmed with the default settings from the standard Renard code with a starting address of '1' on all of them. When you daisy-chain Renards, it is no different than if all the PICs are on the same board (in a logical sense) so in reality you simply have a Ren128 when you plug them together. Just remember each PIC eats up 8 addresses so the next one in line starts at '1' again, not 9 (or 17, 25, etc).

Just to clarify - - you only have a single Renard Type 1 plug-in configured correct - and it is set for 128 channels?

[ctmal]

I think Budude has your issue. If you are daisychaining your 2nd Ren 64 off of your 1st one(a cat5 cable from Ren1 to Ren2) then you just want to have 1 Renard plugin in your sequences set to channels 1-128.

[steve_hirst]

Ok, I have seen this one.. you are plugged into the transmit cat5 connector on at least the first board. change that and you should be good to go. look at the wiki for the right connections.

[Dave Burrows]

Thank you all for your help on this, because this DODO:confused: stuffed up.

Yes it was the plugin set up that required modifing. Use 1 renard dimmer with 128 channels.
I was reading about the wirless rens and got confused.

So thanks again.

Now i can spend some time and play with the pickit3 and trying to flash pics properly...hahaha


Thanks
