Hi all i'm using the ADXRS453 in my board and try to read data from it.
iv'e seen that no matter what im doing, the data bits is allways 0xF080.
any idea why i dont get the correct data?
my problem has been solved. it was something with the bit assignment.
also, i've noticed the start up sequence, do i have to use this sequence? right now im not using it and it seems to be working fine.
This blog post might provide some insight for you on troubleshooting this type of issue. Although it was written for another sensor, it provides a number of important insights into isolating the cause of these type of behaviors. My colleagues and I may post other questions/ideas, but this will be a good starting point.
Connecting to Smart Sensors, it Takes More Than Code
well of course i checked my hardware interface and everything seems to be ok.
i think that my problem is with the bit assignment in the MOSI line.
can you send me an example of read/write sequence for this chip?
The datasheet rev B (on website) has details on pg 14. Are you following those guidelines? What makes you suspect the MOSI line? Have you debugged that on a scope? Also, are you following the recommended start up sequence on pg 20?
Glad to know the problem has gone away! The startup sequence is recommended, so you may want to try it.
