Resolved! Do all FPU operations proceed in a single SYSCLK tick?

This should be simple, but I can't find documentation.   I am running an STM32L4P5 at max clock speed (120 MHz), and I have moved all code to SRAM so it is running with zero wait states.    I have an extensive calculation to do using the FPU -- I am ...

STM32H7 faster using floats than using uint32_t

I made following two versions of the same software to process DMA data, one using floats and the second using uint32_t to try run faster, but as a surprise the first one run faster:  //161 void process_data_ADC1() { float samples1=(2.0f/(float)ADC_B...

Resolved! SysTick and FREE Rtos

Hi to everybody.I'm using H5 and FREE RTOS. I'm porting a project from M3 , than M4 now to H5. I used LL for all the periferals, but moving to HAL isn't a probelm (... but I prefer  LL!).On M3 and M4 I used a timers to "serve" the RTOS scheduler, the...
