Resolved! EXTI Pending Interrupt (EXTI_PR1) still getting serviced even when clearing the pending register
I have a system that uses an STM32L476 controller, where we are using EXTI0 to wake up on a falling edge interrupt.My interrupt service routine used to wake up, contains an IWDG reset, so any time the interrupt gets serviced, we just reset (that's th...

Fast Hartley versus Fast Fourier?
I’m doing some frequency analysis - as usual I trying to minimise the processing cycles to minimise current consumption. I’ve only just discovered the Fast Hartley Transform (FHT). It seems pretty good ( and simple) - I wonder why it is not more wide...
