Oh gosh, you are right! I’m sorry for the delay but I was very busy. I have never thought to rotate the LED matrix because I thought I was right with that (otherwise, if not, no LED would have turned on). Thanks very much! I also take advantage of you for another issue. I have tried to load the arena configuration on the SD card but PControl doesn’t let me do that. Have you any suggestion? It seems that the controller doesn’t communicate to the SD nevertheless at the beginning (when the controller is switch on) PControl finds and initializes the SD card. I’m sorry because of all these questions!

Hi again @Will-Dickson, you are very helpful! Thanks for your kindness!
We have fixed the microcontroller reading problems, actually the Olimex programmer have a 6 pin cable but it is in PDI configuration and not in ICSP. Thus, with an adapter from the existing 10 pin ICSP cable to the 6 pin we have solved it. Now, we have reprogrammed some panels with Atmel Studio 7 according to the Quick Start procedure but at the end the panels don’t display the default address “127”. Our panels display a weird pattern of only 5 led turned on. At this point we don’t know if it is normal or maybe if we have damaged the microcontrollers. We have not tried yet to program through AVRDUDE but likely it will not change because the programming process was gone fine in Atmel Studio 7 apart from the final result.
Thanks a lot again for any suggestions

Hi dear Will,
I’m sorry for late response. After some checkings we have found that the 5DIN cable was connected to the power supply in a wrong way. Anyway we have another tricky problem in the panel boards programming. As previously mentioned we have bought the pre-programmed and addressed FlyPanels-G3 but once mounted the arena we have encountered some problems in controlling the panel pattern (i.e., some led are on with a seemingly random pattern and of these led we could only turn on and off the BUS0 of the arena through PControl). Thus we have thought to program the panel boards from scratch in order to obtain an updated bootloader/firmware. However, once fixed panels board (board+led panel) on the ISP expansion board, powered the circuit via controller and connected the programming device to the 6 pin header (Olimex Ltd, AVRISP mkII) we are not able to read the ATmega168 by mean of the Atmel Studio 7 in the Device programming window.

This is the error display:

[ERROR] Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00, ModuleName: TCF (TCF command: Device:startSession failed.)

Do you have any advice to solve our problem?
P.s: We have already tried to change the ISP clock frequency without successful.

Thank you very much!

Is there anyone suggesting any explanation why, after setting up the preprogrammed led arrays, we're not able to switch them on, and we have to switch off the power supply because the connection cable to the panel system is increasingly going heat ?
It seems to me that somewhere there's a huge resistance to the ingoing current, but I'm not able to find any kind of this with the tester.
In any case, without any attempt to program them, should all leds turn on ? (I should think so)

Thanks for your suggestions about this troubleshooting
