Re: ADXL 345 and duplicate readings

Hello i finally got it to work. I thought i would post my results just incase anyone else is having difficulty. I increased the bandwidth to 800HZ in the library (Line 47: https://github.com/pimoroni/adxl345-python/blob/master/adxl345.py - I changed the line "self.setBandwidthRate(BW_RATE_100HZ)" to...

Re: ADXL 345

Thanks for your help so far. I don't understand how to do this from reading the data sheet. Is there any advice/help/ pointers to achieving the register changes?

Re: ADXL 345

Solution will be to set a faster sampling rate (higher power mode) so that the registers r updated faster. Thank you, I've read the data sheet and a fewer other sources and see what you mean. I'm new to working with sensors and i2c, what do i need to do to stop the sensor from sleeping? Any help ap...

ADXL 345 and duplicate readings

Hello, I have purchased a ADXL 345 Accelerometer and i am getting readings from it. I am measuring at a 100hz and I have a loop in Python that iterates through requesting the axis g's. Every second the loop request about 70 reads from the sensor, 4 consecutive entries are the same readings which doe...

Re: Raspberry PI Sense HAT increase acceleration to 100 read

I found the file in "/etc" and opened it in leafpad, changed the ini but it says "cant open file to write". Any ideas why?

Thanks

OK brill, I'll be programming the solution in NodeRed. Will that work on that platform too?

Raspberry PI Sense HAT increase acceleration to 100 readings

I have a Raspberry PI sense hat. It only records 10 entries a second for the acceleration. Is there anyway this can be increased to 100?
