enum gyroODR #2

Open manitou48 opened 8 years ago

manitou48 commented 8 years ago

The 0 value of enum gyroODR is really 800hz. so your config runs the gyro at 800hz.

Your config of the gyro seems to cause the gyro to draw 24ma (even though data sheet says active is only 2.7 ma??) Paul's gyro config seems to draw only a 2ish ma

According to the data sheet (page 39/50) the top gyro ODR for DR= 000 is200 Hz and the expected current consumption is around 5 mA.

How do you determine the gyro rate to be 800 Hz?

in https://www.pjrc.com/store/fxas21002.pdf table 47, also i have run the sketch counting number of gyro calls per your 500 ms window, and get 400 calls.

Looks like my code assumed the FXAS21000, not the FXAS21002 that the prop shield is actually using. I'll have to check for other inconsistencies.
