I have been playing a bit with the accelerometers on the FR appear to observe the following:
1) The time stamp on events appears to be unreliable, in the sense that the time difference between sequential events is frequently negative, and appears also to be have erratically by jumping an order of magnitude or 2 between sequentially available events. 2) It also appears to be relatively common that a SYN arrives before all 3 axis values are available, making it hard to figure out the meaning of the data 3) There is a significant difference between the readings of the 2 accelerometers when the FR is just sitting there on the desk doing nothing. 4) When you move the FR about, the rate of reports being available appears to become very erratic, in the sense that there are relatively long periods between reports. My questions are: 1) Is this a common situation with the FR (OM2008.12) 2) Is the device driver just buggy? Of course, I realize that my own code might be just buggy, but these features of the accelerometers appear in both my C++ and TCL code, and in the example programs from the wiki references with print statements inserted. Tks for any advice. -- Iain B.
