I have a quick question... Thanks to development of the driver from some nice guys, we are able to get data from the accelerometer. There is one problem. How do we calibrate the values that are outputed from the userspace? All PC's get a different value, and we can't really find the best solution. What is the scientific and smartest way to do this? i.e. of the driver output from the userspace. abonilla@debian:~/hdaps/hdaps-dave-0.02 $ ./ibm_hdaps_userspace /dev/ibm_hdaps x_accel: 409 y_accel: 528 temp: 47 temp2: 47 unknown: 7 If I move the PC 45 deg right.(Looking from front the left side is higher) km_activity (keybd) = 0 km_activity (mouse) = 0 x_accel: 396 y_accel: 579 temp: 47 temp2: 47 unknown: 7 The thing is, people have different values, and I think they are also different depending on where they are. Another question for this kernel inclusion (heh) Should we use Sysfs or should we use the userspace that outputs this data, else what is recomended? Thanks in advance, .Alejandro
