TurtleArtwithSensors has different requirements for non-XO hardware

[walter]

On Ubuntu, using sugar-jhbuild, TA with Sensors fails to launch due to missing moduke alsaaudio imported by audiograb.py

[walter]

the python-alsaaudio module (alsaaudio.so) perhaps should be in the build, but there is a follow up problem for non-XO machines. There seems to be a mode that was added for the XO mic in:

File "/home/walter/Activities/TurtleArtwithSensors.activity/talogo.py", line 3

24, in doevalstep

if not lc.step.next(): stopsignoff(lc); return False

File "/home/walter/Activities/TurtleArtwithSensors.activity/talogo.py", line 1

36, in evalsym

else: result = lc.cfun.fcn(lc, *lc.arglist)

File "/home/walter/Activities/TurtleArtwithSensors.activity/talogo.py", line 2

49, in <lambda>

defprim(lc,'sensor_val0', 0, lambda lc: sensor_val(lc, 0))

File "/home/walter/Activities/TurtleArtwithSensors.activity/talogo.py", line 3

68, in sensor_val

ag = AudioGrab()

File "/home/walter/Activities/TurtleArtwithSensors.activity/audiograb.py", lin

e 47, in init

self.dcmode = Mixer('DC Mode Enable')

I suppose I should be adding alsaaudio module to the bundle. There are numerous other problems with audio that need to be fixed: perhaps this can become a collector ticket for them all:

1. alsaaudio module required
2. pitch doesn't work due to missing real_fft module
3. audio is turned on and off with each sample. It should be left on while a stack is running and TA should detect when it is put into the background in order to free up the device.
4. resistance and voltage blocks should be disabled on non-OLPC-XO-1 machines.

Moving out to the 0.86 release.

The problem is, if you add it to the bundle it will break on different architectures - 64bit etc. Is this functionality not available upstream?

[walter]

The OLPC-specific needs are not upstream (and I cannot imagine they will ever be accepted upstream), so the inclusion of the binary is for OLPC, not other distros.

[walter]

Will resolve in context of 0Install work.

Well, with the work Sascha did on Measure's amixer controls, I managed to rework the audio grab for TA with sensors to no longer have any alsaaudio dependencies. #2035 is relevant to TA as well.
