Question
1) Some accelerometers (about 10/15) response "F3" instead of "F2" reading thePARTID register; most of them started to return the correct "F2" value afterseveral turn on/turn off cycles, without a clear pattern. One of them insteadcontinue to return "F3"."F3" should be the PARTID of the ADXL363, but the marking on our IC iscorrectly 362.
2) Some accelerometers (about 10) had a 2g or 4g offset on some axes. All but3/4 suddently returned to read correct values after some retry (includingon/off cycle).
Answer
Could you try the following steps please:
Power cycle/Turn onWait few msecs before doing any SPI transactionsPerform SOFT RESET (write value 0x52 into register address 0x1F)Wait few msecsContinue with rest of the code (reading/writing other registers)
