I am experimenting with CRC Calculation on a STM32F4-Discovery.As I have seen in the reference manual this MCU is using CRC-32 used in Ethernet. I am also using https://crccalc.com/ (CRC-32/MPEG-2) to validate the results.I just activate the CRC in C...

I am trying to understand the priorities, subpriorities and priority grouping in my stm32f407-Discovery.I would like to have 3 external LEDS (LD_A, LD_B, LD_C) and 3 interrupts (IT_A, IT_B, IT_C) with. IT_A has a highest priority, IT_C has the lowest...

I was reading in "Mastering STM32" and in the intro of PWM pulses (pg355 hard copy) said that "The square waves generated until now have all one common characteristic: they have a Ton period equal to the Toff one. For this reason they are also said t...

While I was reading a book about DMA I came up with some questions. I tried reading AN4031, RM0090 with no better luck in understanding.The problem has to do about bursts in DMA. The questions are theoretical and there is no source code to follow the...
