(source: on YouTube) Speeduino tuning Normally the Xtal (for STM32) is in the range from 4 to 26 MHz and for reach the max MCU frequency is a must to use the internal PLL (phase looked loop). The PLL multiply the Xtal frequency in order to reach the desired max MCU frequency. Now, for explain, in a real application, how to configure the clocks we use the STM32F4-Discovery.

A complete listing of technical documentation is provided below. Due to the size of the documents and Sample Application software environment, FTDI Chip recommends that purchasers of a VM800P development system, first acquaint themselves with the DS_VM800P and DS_FT800 datasheets, after which familiarity with EVE's pseudo language found in the Programming Guide is advised. Intro. Note: This post is the first in the series. Here you can find part 2, part 3, part 4 and part 5.. Since 2015 I was following the whole machine learning hype closely and after 4 years I can finally say that is mature enough for me to get involved and try to play and experiment with it in the low/mid embedded domain.
做小封装产品设计的朋友或许知道3225-4pin的晶振，为何8mhz晶振批量价格要到2元一片，而16mhz晶振只需要0.4元甚至更少。究其原因是因为3225封装的晶振目前全球最低频率一般为8mhz，而国内8mhz达不到精度指标，所以市场上的8mhz晶振一般为进口晶振，因此成本被垄断。 Newest Atmega328 16mhz Pro Mini Microcontroller Board Compatible , Find Complete Details about Newest Atmega328 16mhz Pro Mini Microcontroller Board Compatible,Pro Mini,Atmega328,Microcontroller Board from Other Electronic Components Supplier or Manufacturer-Shenzhen City Caite Gifts Co., Ltd.

January 2020 AN2867 Rev 12 1/54 1 AN2867 Application note Oscillator design guide for STM8AF/AL/S, STM32 MCUs and MPUs Introduction Many designers know oscillators based on Pierce-Gate topology (hereinafter referred to as 本文则给出了一种低成本的控制方案，使其功能在 stm32控制器的控制下也能充分发挥。1 伺服电机控制系统设计方案主控板以 mcx314 为核心， 采用 stm32f427zit7 微控制器作为主控器， mcx314 的时钟频率由外部决定，本系统采用了mcx314 默认的 16mhz 频率作为时钟信号。
stm32微控制器學習者一開始用的晶振一般是2pin的8mhz晶振，一旦正真做產品研發的時候，使用到3225的8mhz晶振的話，成本是個不小的挑戰。 筆者現針對這個問題，提出使用16MHZ晶振代替的方法。 Search for "STM32F103C8T6" and "maple mini STM32" on eBay - the best deals are under £3.50 delivered some genuine Maple Minis can be found for about £14 - they are no longer in production - - - - (more later) Developers on the Arduino Forum have managed to embed boards like this within the Arduno IDE
