I can't read right result from the MMA9553L,

When Read configuration variables,I get the first four bytes:0x15,0xf0,0x00,0x10;

When Read status variables,I get the first four bytes:0x15,0xf0,0x00,0x0c,it's different form the MMA9553LSWRM .

Anyone help?

Guys, Thank you!

Now I find a problem,vdda and vdd is important to the access!

But I can't get good results according to the power design of the datasheet!

Maybe the bytes you sent to MMA9553 is not correct. You can email to Freescale for reference manuals.
