Hello guys,
I am using an NRF chip with Cortex M4. Currently I am reading data from an accelerometer (12 signed bit ADC) and I have to get peak velocity. For that I am using the Omega arithmetic algorithm, as follows:
- remove offset from…
Hello everybody,
im using the Math.h file to do a rfft with 1024 points und q15 datatype.
So far everything works fine, and I get good results. It needs a computation time of ~720us on my CortexM4 @100Mhz.
This is very Impressive, but to long for my application…
Hello everyone. I write FFT, it's ran! But it run very slow speed, I try on STM32F103C8T6 72MHz and used timer to measure time, the result about 360ms and I can't run another program. Somebody help me please! Thank all!
My code here: the DFT http…
Hi,
I am exploring the CMSIS DSP library. After playing for a while I have 2 questions:
-in case I want to evaluate DFT over bigger data window than 4096 I would need to provide Twiddle Coefficient array for particular size and make aplit the data set…
