Daniel Wee replied to james a's discussion best way to just get pitch data from arduimu
"Get the ArduIMU+ V2. Load up arduimu.pde and the rest of the files will load automatically. The GPS while not absolutely necessary, supposedly helps with centripetal force corrections in dynamic situations. It all depends on the type of application…"

In my latest flight test with the ArduIMU, I found that I probably need to tune it a bit. First of all, the data:-http://vimeo.com/10887900My preliminary observations are that the output converges onto the accelerometer settings too quickly. This…

Daniel Wee replied to Ony Arifianto's discussion Does anyone have ArduIMU+Pilot firmware ?
"Does anyone know which version of firmware does the current ArduIMU+ V2 ship with?

I was trying V1.5 and V1.6 but they don't appear to behave like the version that was shipped with. Is there a link where I can find that particular sketch? Thanks…"

Daniel Wee commented on Krzysztof Bosak's blog post Testing 'ArduIMU V2 Test' viewer by HappyKillmore with FLEXIPILOT Single Gyro
"Hi Krzyszstof,

Does your viewer work with the version 1.6 of the IMU code? I am trying that out and the default compile of the latest release doesn't seem to talk to the viewer very well. Could you let me know if this works? Thanks.

Daniel Wee commented on William Premerlani's blog post roll-pitch demo firmware for the UAV DevBoard
"Fantastic, that's what I have been testing with various gyros. I have a bunch of temperature-drift profiles for about 6 gyros types. The one I am trying to use is the LPR530. The LISY300AL is surprisingly temperature stable though. The ADXRS601 has…"

Daniel Wee commented on William Premerlani's blog post roll-pitch demo firmware for the UAV DevBoard
"Thanks again Bill. I am actually porting this to a 12-bit ADC platform to see how things work out, hence the questions. I've found that the ADC samples can be quite noisy on my board (what appears to be up to 5-10mV of noise on the samples). I am…"

Daniel Wee commented on William Premerlani's blog post roll-pitch demo firmware for the UAV DevBoard
"Thanks Bill. I have looked at the new RollPitchYaw demo and that does make sense now. I cannot, however, find an updated RollPitch demo. Is there one? Or can I just remove the adj_accel, yaw_drift and perhaps some other functions from the imu_demo…"

Daniel Wee commented on William Premerlani's blog post roll-pitch demo firmware for the UAV DevBoard
"I am looking at the RollPitch Demo files posted in the link above - assuming that this works with the UAV Dev Board (which uses the LISY300AL or the ADXRS401). But looking at the analog2digital.c file, I am a little confused. First of all the pin…"

Daniel Wee replied to Monroe Lee King Jr's discussion AuduIMU Questions
"Don't forget - on the moon you will get different gravitational readings so your accelerometric code will have to handle that as well.

I was looking at Premerlani and Bizard's paper and got thinking about what is needed to enforce the orthogonality of the DCM. From what I can tell you would need to track yaw as well in order for this to work right since this is a 3x3 matrix.Does…
