• Cortex-A35 Counter-timer Physical Count register (CNTPCT_EL0) always reads zero
    Counter-timer Physical Count register CNTPCT_EL0 always reads zero on FVP_Base_Cortex-A35x1. I expect the value of this register to change over time. I set $CNTFRQ_EL0=35000000, and $CNTP_CTL_EL0...

  • FFT CMSIS always showing zero for non-multiples
    Running 4096 point FFT with 8 cycles of data. as per my sampling rate the frequency spread is 6.25Hz. So Expecting the fund at 8th bin which is coming properly. But expecting 175Hz spectrum at 28th Bin...

  • FFT CMSIS always showing zero for non-multiples of fund frequency
    Hi all, I am using STM32H7 controller. I have 2 signals one at 50Hz (Fund Frequency) and another one at 175Hz (20% amplitude of 50Hz), My sampling rate is 25600 (About 512 samples / Cycle of fund frequency...
