Actually, we did. He tested it with a touch sensor, and got the expected readings, so that proves it isn't the FW.mightor wrote:You still never eliminated the one common thing: the firmware.

He tested it in RAW mode, and it gave the proper readings of ~184 and 1023. That means that he was indeed seeing RAW values, and that the FW wasn't messing around. You're right, it does prove that the touch sensor works fine, but since he replaced it with the pressure sensor, and that DIDN'T behave like it should have, it seems pretty obvious that the sensor itself is the issue.mightor wrote:No, it just means that the TOUCH sensor works fine.

hi,
indeed, that's really odd:
In the test program I'm reading "raw" values in both cases from sound sensors,
S1 configured as: SetSensorType(S1, SENSOR_TYPE_SOUND_DBA); SetSensorMode(S1, SENSOR_MODE_RAW); val1 = SensorValue(S1);
S2 configured as: SetSensor(S2, SENSOR_SOUND); val2 = SensorRaw(S2);
attaching the sound sensor:
S1 shows (quiet) 13 ->->-> (loud) 1023
S2 shows (quiet) 988 ->->-> (loud) 263
taking touch sensors instead:
S1 shows (released) 0 -> -> -> (pressed) 999
S2 shows (released) 1023->->-> (pressed) 186
What the hell did the Lego people think when they established (at least) 2 completely different inverse "raw" measuring results for one and the same single sensor ?!?
