So I found this on SparkFun and I’d like to use it to monitor vibration on a machined part. Max frequency I expect to see is 1500 Hz and the ADXL can go to 3200 Hz internally but I’m concerned about the processor. I’d be using an Uno to poll the registers and log the data to an SD card, which has some unknown number of instructions/cycle and the Uno has only 16 MHz.
Is logging at 1500 Hz realistic or am I crazy?
Sorry for bring this up…
As i am also planning to use the ADXL345 for vibration analysis.
Can someone please kindly explain to me what is this frequency you guys are talking about? What and how to set the most ideal frequency to use? I am currently really confused now about natural frequency/ sampling frequency / spi clock frequency and frequency output rate ??
I basically uses the adxl345 to measure the acceleration. I am required to convert it to velocity as per the ISO 10816 standards, however according to the formula, i need find the frequency at this particular instance, which i am have been trying to figure out how to get, before going into FFT.
My lecture was also saying how adxl345 isnt a legit accelerometer for frequency analysis?
