That was indeed the problem, I input the correct port and it’s working. Now I am running into another problem where those rows don’t light and the one column still is out. I checked and everything really seems soldered down correctly but there is an interesting thing that happens when I bend the board ever so slightly, see video here:

Alright, thank you for that information. Attached I have a video showing that I have set the board for that option and what it is currently doing. Perhaps I am missing a step somewhere but I still cannot manage to make it work. Sorry for the blurry video in advance.

Also, currently the Arduino has auto-selected Mega 2560/ Mega ADK as the default board. It’s a 328P as far as I understand, but there are a few choices for that.

Edit: Tried all the 328P boards, uploaded and verified all, ran serial monitor and then started MirrorPeggy. Nothing is happening.

I clicked Verify and it prompts me with the following in grey letters: “Binary sketch size: 1,740 bytes (of a 258,048 byte maximum)”

I did it on both the tty and the cu serial ports it shows in Arduino. When I uploaded on either of those the lights flashed for about a second or two and went back to the same pattern seen in the video. 

I open MirrorPeggy and it opens fine on my Mac but nothing changes on the Peggy display so I’m assuming I missed a step here somewhere.

Ok, I installed the FTDI VCP Driver, I clicked upload and it says “Done compiling” for the RecVSerial file. Means it’s installed on the board correct?

Next, I have MirrorPeggy running on Processor.

Now, how do I have the two communicate with each other?

I really appreciate the help.

Hello Windell,

Sorry about that, I did alter my post. I didn’t see a reply from you so I figured you hadn’t seen it yet.

Here is what I am seeing right now when hooked up and trying to upload to the Peggy…

[ShaneA]

Thank you for the help Windell!

I have downloaded both Peggy2Serial and Peggy2_RecvTWI folders. Also, Arduino and Processing.

I’ve loaded the Peggy2Serial library to Arduino. Ok, that’s done so now I went into File>Examples>Peggy2Serial>RecVSerial and thats open. Now how do I load it to the Peggy? I clicked Upload and it does not recognize my serial line to the peggy (using a Mac). The computer also doesn’t recognize the Peggy when I plug it in either.

What do you suggest I do? I may be reading your previous instructions incorrectly and if so my mistake.

Also, this is my Peggy2 hooked up to the wall supply. Looks a little wonky, I hope this is how it should look currently (in serial mode).

Thank you!

So just (2) 229ohm resistors are needed and I’m good (in theory)? Fantastic!

On to my next questions, I’ll start a separate topic soon.

Thank you!

[ShaneA]

I looked further into the datasheet and I see that somehow the CP still allows up to 90mA (from what I see). So If I want 85mA it says I need a 229ohm resistor on the chip. So since there is two per side does that mean I need replace all 4 resistors (2 1k and 2 trimpots) with 114ohm or just short the trimpot and run one 229ohm per side?

Also, it would have to be a 114ohm that holds over 2.5w?? Or how much wattage?

Thank you!

I just checked the driver chips, they are different then what I was supposed to get. 

I was supposed to receive STP16DP05 drivers but instead I received STP16CP05 instead.

Normally I wouldn’t care but the DP (what I was supposed to get) is between 5-100mA where as the CP is only 5-80mA.

I really need these to be at least 85mA per LED…
