In the mean time we have been working using the hearables feature set. we are now loading the aprrox 6k program code into the bma456, then burst read the first 0X5D registers to change and write back to the device. It now makes no sense as the first 0x5D bytes from the reset of the features should match the reset conditions as outlined in the data, but they do not and we can get now sense from the code. the byte indicating the code is running is comming back ok. nothing seems to make sense. can you add any light to this very low level problems with the device thanka gary ...

the number of rotations is related to truck tyres and how many km each tyre travels, this is not life critical. This system fits with our patented wheel bearing temperature monitoring systems for large truck fleet operations around the world. The key to low power is your chip logging rotations upto a set point then triggering an interupt. We also use this interupt and real time in the main processor to calculate if the truck is moving or not. thanks Gary   ... View more

thanks for the reply. the idea with this chip and why it was chosen was to use the internal counter, like the step counter and high water mark to count the rotations of the wheel and only interupt the master processor when this high water mark is reached so to lower the overall power consumption. maximum roration of the sensor is around 30Hz. So each rotation is stored internally. hope this is enough information. thanks Gary ... View more

We have mass marker application for tyre rotation and counting, this runs on a small embedded processor in 8051 assembly. ideal solution is a finished code set from you guys that we can download and adjust some of the parameters. Hope this makes sense as we are getting frustrated with not being able to deliver the solution we require. The reason we picked this sensor was low power and buffer so that main processor can remain in low power longer as it runs in side the wheel hub on small battery. thanks Gary   ... View more
