| Time: 7/3/2008 4:35 am From: Racer Comment: Hi! nice work! How good is the resolution of the values and the frequency they can be polled? keep on! |
| Time: 7/3/2008 7:55 am From: Scott Comment: Glad others are finding this useful! As to the poll rate: Got me. So far it seems to be happy at at least 20 times a second. I haven't (yet) tried higher, though the API doesn't seem to respond well to being polled in a tight loop. |

| Time: 7/7/2008 12:16 am From: Koush Comment: Hello again Scott! I've written a managed wrapper for the HTC Sensor SDK and published it at my blog (and linked back to yours of course!) Again, great work. http://blog.enterprisemobile.com/2008/07/using-htc-diamonds-sensor-sdk-from-managed-code/ |
| Time: 7/8/2008 4:33 am From: j0bro Comment: Hi Scott, I came across this blog of yours and I'm interested in whether this would work in c# as well? Or is your code stuck to C++? Thanks in advance! |
| Time: 7/8/2008 7:25 am From: Scott Comment: My code is C/C++ only. Take a look at Koush's reply. |
| Time: 7/9/2008 6:08 am From: Daniele Comment: Hi, i’ve tried to use your code and I receive an error when execute this row Dim htcGV As HTCGSensor = New HTCGSensor() the error is: InvalidProgramException Can you help me? |
| Time: 7/9/2008 9:49 am From: Scott Comment: That looks like VB code, which would mean you're using Koush's Managed solution. I'd suggest you contact him for help, or try posting on his blog, I'm afraid I really don't have the spare cycles to investigate issues in the managed solution. |
| Time: 7/9/2008 1:15 pm From: Nuke Comment: Scott, do you know any way to recalibrate the tilt sensor?! |
| Time: 7/9/2008 3:07 pm From: Daniele Comment: It's right, your unmanaged is working fine.... I go to study your version (some problem with C++ but ....) Thanks and sorry. |
| Time: 7/9/2008 6:01 pm From: Scott Comment: Sorry, I haven't determined how to recalibrate the sensor, yet (or even if it's possible). I'll look into it, but no promises of when I'll be able to figure things out. |
| Time: 7/10/2008 10:52 am From: Koush Comment: I had a post on xda-developers that it would be possible to recalibrate the sensor by creating a new HTCSensorSDK.DLL that acts as a pass through to the real DLL. It could then tweak the output values as it pleased. But HTCSensorSDK.dll is on ROM (I think) and note removable. The callibration program would need to be flashed onto the device via a new ROM. |
| Time: 7/10/2008 1:11 pm From: Nuke Comment: Thanks Scott! mmmh i whould like use original ROMs. it could be nice if HTC release a patch..... |
| Time: 7/10/2008 4:05 pm From: Scott Comment: Koush: That would work for some apps, but not for others, for instance, Opera will still be confused about which side of the device is "up" (assuming your device is far out of calibration), as it doesn't use the HTCSensorSDK.dll to get the sensor information. In the end, it'll be up to someone to discover a calibration API, or ideally, for HTC to release a real SDK letting us know exactly how to do that sort of thing. |

| Time: 7/15/2008 2:22 pm From: ... Comment: The light sensor does not seem to work if the screen is off. My guess is that the HTCSensorQueryCapability (don't know the signature) would return false. Any ideas on how to get around this? I looked to see if I could figure out if there was a driver I could turn on, but didn't have much luck. Any thoughts? |
| Time: 7/15/2008 3:50 pm From: Scott Comment: Sorry, I haven't yet had a change to look into the light sensor. I'm going to look into this, but I really don't know when I'll have a chance. |
| Time: 7/15/2008 4:04 pm From: ... Comment: The same holds true for the accelerometer. You can't query when the screen is off. I think that either the driver is off or they are doing some power state check, but I don't know enough about disassembly to figure it out. |
| Time: 7/31/2008 9:02 am From: Riley Comment: nice find there. Currently, i am holding samsung omnia. Similar to HTC, they are not releasing the accelerometer sdk either. I'm interested in reverse engineering the dll. could you point me to some direction/guide how should i go about do it? it would be great for developing motion sensing games that will work across more handset :D |
| Time: 8/4/2008 10:30 am From: JD Barclay Comment: You are the man. Thanks! I'll be getting my HTC soon and start the play... For anybody there, look at this app built for IPhone: http://www.dynolicious.com/ It uses the iPhone g-sensor to detect car acceleration and calculate several values such as HP, speed, etc. Im not iPhone fan but really admire this app... Has anyone done something similar over WM platform? |
| Time: 8/13/2008 2:12 am From: Dale Lane Comment: How specific is this to the Diamond? Could it also work with the HTC Advantage? |
| Time: 8/13/2008 10:01 pm From: Scott Comment: Got me. If the Advantage has a tilt and motion sensor, it might work. That's all up to how exactly HTC implemented the SDK on the advantage. Someone with some development experience is going to need to try it out, and that can't be me since I don't have an Advantage to play with, sorry. |
| Time: 9/7/2008 6:00 am From: Cosmo Comment: Scott, how did you figure out this API by the way, what techniques or tools helped. There are other API's to discover! |
| Time: 9/7/2008 10:25 am From: Codemaster Comment: Hi, Nice app could you turn it to VB.NET ? Greats code master |
| Time: 9/9/2008 2:44 pm From: Scott Comment: Sorry, no VB client. Koush has a C# client that he posted a link to above that might help you out. As for how I did this, maybe that's a good idea for a series of posts coming in the future. |
| Time: 9/10/2008 1:08 pm From: Jamie Comment: How does Koush manage to get GetGVector x,y,z from the data in the SENSORDATA struct? SHORT TiltX; // From -1000 to 1000 (about), 0 is flat SHORT TiltY; // From -1000 to 1000 (about), 0 is flat SHORT Orientation; // From -1000 to 1000 (about) // 0 = Straight up, -1000 = Flat, 1000 = Upside down WORD Unknown1; // Always zero DWORD AngleY; // From 0 to 359 DWORD AngleX; // From 0 to 359 DWORD Unknown2; // Bit field? |
| Time: 9/10/2008 1:36 pm From: Scott Comment: I'd try asking on his blog, I don't think he monitors my blog for questions :) |
| Time: 9/10/2008 2:21 pm From: Jamie Comment: Good idea! His comment box wasn't so obvious, found it now though. |
