How to config interrupts priorities for STM32 Posted on January 30, 2013 by Green I am testing nested interrupt recently on my STM32 dev board in order to ensure the relationships between nested interrupts are clear for me. You'll recall that event counters, exceptions, PC value and data traces can all be output by the DWT, so in this post we'll provide a couple of examples of how to use that functionality. 14h Changes Version V6. In this tutorial, I am going to show you how to create 1 microsecond delay in STM32. DWT assumes that the orignal signal is "sampled" with the scaling function and the sampled signal is just scaling coefficients (ie. 指令系统: Cortex-M3只是用32位的thumb2指令。在. cortex m3 dwt 07-19 阅读数 stm32f103驱动人步进电机程序,值得参考,stm32f103驱动人步进电机程序,值得参考stm32f103驱动人步进. So it seems to me that an STM32F103 with all the CPU cycles and available timers should be able to do even better than that. > > Correct. se] has joined ##stm32. Look at the definition for __IO (and the others in the group) and you are likely to quickly see your answer. 在学习和使用STM32F103系列MCU中,研究了一下CM3手册,发现调试组件中有对CPU时钟进行计数的功能(CYCCNT),如下图: 因而可以利用它进行延时。代码如下: #define DWT_CR *(volatile u32 *)0xE0001000 #define DWT_CYCCNT *(volatile u32 *)0xE0001004.

Before calling dwt_softreset, I had reduced the SPI rate to very slow, <2MBits/s, which did not feel like a SPI problem. xcodeproj/project. As a result, PWM Period relies on both Prescaler and Counter Period (Autoreload register). Hi, I'm trying to access the 2nd Jtag in the daisy chain using the JLink Commander. I decided to order an ST-Link/V2, which is available for a few Euros (I paid roughly 6 EUR for mine). I use stm32l432kc to communicate with dw1000.
