Balance Board state type Unknown Extension Attached

[dolphindream]

The trunk-r197 does not work with the Balance Board. The wmdemo (and my application using the libcwiid) connects fine to the balance board (and is able to recognize the button states) however it does not read the sensor data since the state type reports an UNKNOWN type. The wmdemo has "Unknown extension attached" (extension reporting on and print the current state). Here's the output:

./wmdemo
Put Wiimote in discoverable mode now (press 1+2)... Note: To demonstrate the new API interfaces, wmdemo no longer enables messages by default. Output can be gathered through the new state-based interface (s), or by enabling the messages interface (m).

1: toggle LED 1
2: toggle LED 2

4: toggle LED 4
5: toggle rumble

b: toggle button reporting
e: toggle extension reporting
i: toggle ir reporting
m: toggle messages
p: print this menu
r: request status message ((t) enables callback output)
s: print current state
t: toggle status reporting

The code seems to match the debugging data at wiibrew.org, but I don't have a Balance Board to verify with. Can you post the contents of your 0xA40F0-0xA40FF?

Using the latest svn version the wmdemo.py seems to think that the balanceboard is a motionplus attachment.

a
s
Report Mode: ACC NUNCHUK CLASSIC BALANCE MOTIONPLUS
Active LEDs:
Rumble: Off
Battery: 90
Acc: x=41 y=41 z=41
MotionPlus: angle_rate=(4227,3752,10437)

How can I get the contents of those addresses?

[dsmith]

Use wmgui, under the View menu, choose the Memory Read/Write? option.

I'm using r201 (Package from Ubuntu 10.04) and I have the same problem, it detects my balance board as a MOTIONPLUS attachment.

I altered the wmdemo.py to print out the raw state if it helps: s Report Mode: Active LEDs: Rumble: Off Battery: 89 {'led': 0, 'rpt_mode': 0, 'ext_type': 4, 'rumble': 0, 'error': 0, 'battery': 186}

I cant get wmgui to read the data. Can you confirm that I have the right settings? Under Memory Read/Write?, I have the offset as 0xA40F0, length as 0x0000F ? And are we reading an eeprom or register? Either way I get "Wiimote Read Error" and:

Non-successful handshake Report send error (read)

at the console.

[kyleanderson]

Ah, I got it, just a typo on the address and you want a register:

0x00A400F0: FF FF 00 00 FF FF 00 00  00 00 00 00 A4 20 04

I just installed and compiled trunk, and this is fixed. I would mark this as closed, but I'm kind new here :)
