How many number of analog pins does APM 2.0 have?

Started this discussion. Last reply by Itay Guy Sep 6, 2013. 4 Replies

According to the DIYdrone website, APM 2.0 should have 12 analog pins. However, when I tested it out, only A0~A8 which corresponds to 54~62 work as analog pins, but the rest 3 pins do not work. I…Continue

"Hi Dr. Sudesh, I think that post was over a year ago. Might be a good idea to create a new forum, as I think an alternative to DCM as Kalman might be interesting to people out there, who can reply to you. Regards, Shyam."

Hello,I am currently working on APM 2.0 to implement Kalman filter using GPS and INS data using 9 by 9 state matrix,  [P_x,V_x,Pl_x,P_y,V_y,PI_y,P_z,V_z,PI_z]', where PI_x,PI_y, and PI_z represent platform tilt about x, y, and z axis.A problem is that newly updated global matrices X and P are not transferred to next iteration although I defined those as global matrices.As far as I tested, a single global variable which is defined before void setup() works well as a global variable in that the…See More
