hi all, finished my built of TB2 kit, it powers on, and lcd lits up and led as well..but blank screen..nada…played with contrast, no luck..
i cant post pic here i guess..triple checked all solder joints…
any ideas??? sent Moshang a message..
thanks MarcoNovember 12, 2015 at 7:35 am #3502
it is working now…I re-uploaded the firmware and now works fine…thanksNovember 13, 2015 at 4:52 am #3504
Does the screen do anything if/when you press the red reset button by the two USB ports?March 4, 2016 at 10:05 am #3672
I received a prebuilt recently, uploaded the firmware using 1.6.5 and powered up and get a blank screen. Well, the first line looks like 16 blocks and the line below is empty. I’ve never used an arduino before but it seems to have uploaded the firmware correctly.
When I received my TB2, there was a note that I should add a chip that was missing – did that. The dot on the chip is very faint, printed on the chip unlike the picture you sent, but it looks correct.
I’m not sure how to debug this but am willing to try a few things if you point me in the right direction.
I’m using OS X El Capitan, Arduino IDE 1.6.5. I downgraded the Arduino SAM board library to 1.6.4 to allow compilation (I was getting an error with the latest and google helped – people suggested the downgrade and it worked). Ive not tried latest IDE meet but might later tonight.
My screen does nothing when I press reset button.
Any ideas?March 4, 2016 at 1:36 pm #3673
It sounds like you have the same issue with your board, as I do with the clones I sell on the site. Long and short of it is that you have to press the red reset button for the firmware to run once you see the top line of solid blocks. See here and let me know: https://groovesizer.com/attack-of-the-clones/March 4, 2016 at 7:58 pm #3674
I tried that and no luck. I grabbed a cheap clone from Amazon rather than expensive ones that sometimes (if you believe the reviews) are fake. I’ll pick one up from mouser as I’ve lost trust in Amazon not providing fakes for many things now. I’ll let yo know how I fare.March 5, 2016 at 7:53 am #3675
Can you confirm that uploading to the board is working (try something simple like the blink example)? I tested the build before I sent it out (all but the MIDI input, ha), so I know it was working here. It works whether the optocoupler IC (for the MIDI input) is mounted or not. I’m still on IDE v1.6.5 as well, and I’ll stay with it until I find time to troubleshoot an issue with the latest IDE that breaks the Attack! firmware’s file system.March 8, 2016 at 10:42 pm #3677
K, I tested the led blink example and it is blinking – seems the board is working.March 8, 2016 at 11:12 pm #3678
I did notice that a preference file is being written to the sd card by TB2:

Got new board today from mouser and we are working fine. Thanks so much for the help. Ironically, the IDE told me the new Arduino board was from an uncertified manufacturer but it worked fine. Thanks again for the help!March 10, 2016 at 12:17 pm #3680
OK, great – yeah, the uncertified manufacturer message is probably a result of the whole arduino.cc vs arduino.org debacle.
