http://stm32f4-discovery.com/2015/01/properly-set-clock-speed-stm32f4xx-devices/ I see that you have problems with your devices when you don’t know even (and you don’t even ask) on which speed your device is actually running. Speed of your device depends on PLL settings or clock ...
In my application ESP32C6 configured as a SPI slave and stm32 configured as a SPI master. I have tested using this example receiver<https://github.com/espressif/esp-idf/tr ... e/receiver> as it is. When I increase the clock in master side, the slave is receiving and transmitting on...
1、rosserial方法,rosserial是官方对arduino提供的一种简单的通信协议,本人对这个库进行了一些改动,使其可以在STM32上进行使用,通过使用这个协议可以在STM32或者Arduino发布和订阅节点数据,详细的移植和使用参考之前的两篇博客:ros下使用rosserial和STM32F1/STM32F4系列进行通信(MDK5工程): STM32(MDK)中如何使用ROS自...
STM32 的时钟系统由外部晶振、PLL(锁相环)和内部 RC 振荡器组成。时钟系统主要提供了处理器时钟,以及可选的外设时钟和RTC模块时钟。 其作用包括: 为处理器提供准确的时钟信号,保证处理器、总线和外设的正确工作。 通过PLL 的倍频功能,产生多种频率的时钟信号,满足不同外设的时钟需求。 通过时钟系统提供的时钟分频...

Even better, however, would be to enable the use of DMA for high speed SPI transactions, which wouldn't tax the CPU at all. I've heard that it's supposed to be on the roadmap soon, right? So fingers crossed. Target(s) affected by this defect ? Tested on STM32F429ZI. I assume...
it is recommended to use an external crystal to generate the timing pulses. An instruction is executed by fetching it from the memory and then decoding it. This usually takes severalclock cyclesand is known as theinstruction cycle. The STM32 family of microcontrollers can operate at up to 168...

STM32 wireless MCUs use an external oscillator high-speed clock source as the base for RF clock generation. HSE accuracy is essential for RF system performance, and the external oscillator is therefore fine-tuned to achieve the highest clock accuracy. The f...
