Controller mode not matched (got 1/got 63)

[Anonymous]

Dear Bill,

first of all, thank you for your library and the support you’re giving to it.

I’m new to your library, but not to Arduino and electronics. Actually, I’m using an Arduino clone – specifically, a JeeNode v6 – that runs on 3.3V so I think there’s no issues that could be related to pullup resistors & co, and I’ve done my job of mapping the PSX-port pins to wire colors, then to the controller pin, then to Arduino numbering convenctions: actually I can comunicate with the controller, but I can’t get your library to work.

I have a silver SONY-branded SCPH-10010 DualShock 2 Analog Controller. Turning on debug mode, running your sample sketch unmodified (except for the pin mappings, changed to 5,16,15,6) when the controller’s led is off I see this communication going on:

OUT:IN
1:FF 42:1 0:10 0:FE 0:FF 0:FF 0:FF 0:FF 0:FF 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0
OUT:IN
1:FF 42:1 0:10 0:FE 0:FF 0:FF 0:FF 0:FF 0:FF 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0
Controller mode not matched or no controller found
Expected 0x41 or 0x73, got 1
No controller found, check wiring, see readme.txt to enable debug. visit http://www.billporter.info for troubleshooting tips
Unknown Controller type

then I press the “analog” button so that the led turns on, then I reset the micro without powering off the controller, so that the led stays on, and I see this different communication:

OUT:IN
1:FF 42:63 0:10 0:FE 0:FF 0:70 0:62 0:78 0:4 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0
OUT:IN
1:FF 42:63 0:10 0:FE 0:FF 0:70 0:62 0:78 0:4 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0 0:0

Do you have any suggestions? Any help would be appreciated.

Cheers!

Did you try all the steps in the troubleshooting guide yet? This looks like it could be a pullup or clock problem.

Dear Bill,

I’m sorry to have annoyed you: seeing that your library already turns on the internal pullup on the data line, and given that my MCU was running at 3.3V I tought no additional pull-ups would be needed… and deliberately skipped the step about pull-ups in the troubleshooting guide.

Thank you so much,

Carlo

Well… I forgot to mention that now, with a 10k pull-up wired between data-line and 3.3V, it’s working properly. At first I tried with a 20k pull-up (first resistor that came to my hand) but it wasn’t enough.

No annoyance. Just wanted to make sure you tried everything before continuing! Glad you got it working.
