mma7260q
Hello,does any body have used MMA7260 to get movement position? Can I get some relational technical document please? I try to use MMA7260Q to get the accuracy compressing movement distance. The range of the movement is 4-5cm. I have red the technical document (AN3397) and have done some experiments according to AN3397, but there still are some problems.I integrat acceleration twice to get the position. Unfortunately, the result is aways biased and the error in my position estimate grows exponentially. Some error maybe kept in my calculation or hard workware design, so calculating position have large errors. I expect for some help from you. Thank you!
