STM32F103 devices use the Cortex-M3 core, with a maximum CPU speed of 72 MHz. The DWT is usually implemented on most Cortex-M3, M4 and M7 devices, including e. 最近有个项目需要用到stm32f407zet6这款芯片,其中有一个串口收发数据的应用。因为之前有用过stmf32f103zet6通过dma收发数据的方案,所以我.

Typically this is used as a timebase for an operating system (for example to allocate time slices) although this example will use it as a simple periodic interrupt source. To get an accurate time measurement it is possible to read the current value of the prescaler counter, stored in the RTC_DIV register, without stopping it. Best Regards. How to precisely measure microseconds with STM32 I received this apparently simply question from a reader of this blog: how can I delay a fistful of microseconds in STM32? That is, how to measure microseconds precisely in STM32?. I was wondering if anyone could point me to the correct location of a delay microseconds function within the existing firmware.

Nyquist theorem assumes that the signal is "sampled" with the sinc function (or equivalently bandlimited to fs/2 and sampled with dirac delta). Den STM32 gibt es von ST in unzähligen Varianten mit variabler Peripherie und verschiedenen Gehäusegrößen und -formen. They are write-protected by the RTOFF bit in the RTC_CR register, and a write operation is allowed if the RTOFF value is ‘1’. It sends its data via the ITM and never seems to get mentioned in letters home…but when we talk about ITM, you can assume the DWT is along for the ride too.
