STM32 F4 SPI Accelerometer

STM32 F4 GPIO Modes Goal: creating a visual summary of GPIO configuration modes. The summary at the bottom shows the major configuration choices. Basic electrical info: GPIOs can sink or source up to ±8 mA, and sink or source up to ±20 mA (with a rel

STM32 F4 ADC DMA Temperature Sensor Goal: detecting temperature variations using a temperature sensor, ADC with DMA and TIM3 as a trigger (ADC sampling frequency = TIM3 trigger frequency). Note: Using TIM3 as a trigger is suited for monitoring temper

STM32 F4 DAC DMA Waveform Generator Goal: generating an arbitrary periodic waveform using a DAC with DMA and TIM6 as a trigger. Agenda: Modeling a waveform in MATLAB and getting the waveform data Studying the DAC, DMA, and TIM6 to see how it can be u

STM32 F4 General-purpose Timers for Periodic Interrupts

STM32 F4 Clock Sources Goal: routing clock sources to the microcontroller output pin (MCO1) High-speed internal (HSI) clock is 16MHz High-speed external (HSE) clock is 8MHz (very precise) PLL CLK is configured to be 84MHz because I have a 100MHz osci

在我们刚使用spi时,对于spi的io口配置可能会有一些疑惑吧,miso明明是一个输入口却配置成了复用推挽输出,是不是会有一点疑惑呢? GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4 | GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;    

STM32--SPI接口 宗旨:技术的学习是有限的,分享的精神的无限的. 一.SPI协议[SerialPeripheral Interface] 串行外围设备接口,是一种高速全双工的通信总线.在ADC/LCD等与MCU间通信. 1.SPI信号线 SPI 包含 4 条总线,SPI 总线包含 4 条总线,分别为SS .SCK.MOSI.MISO. (1)SS(SlaveSelect):片选信号线,当有多个 SPI 设备与 MCU 相连时,每个设备的这个片选信号线是与 MCU 单独的引脚相连的,而其他

SPI  是英语 Serial Peripheral interface 的缩写,顾名思义就是串行外围设备接口.是 Motorola首先在其 MC68HCXX 系列处理器上定义的. SPI 接口主要应用在  EEPROM, FLASH,实时时钟,AD 转换器,还有数字信号处理器和数字信号解码器之间.SPI,是一种高速的,全双工,同步的通信总线,并且在芯片的管脚上只占用四根线,节约了芯片的管脚,同时为 PCB 的布局上节省空间,提供方便,正是出于这种简单易用的特性,现在越来越多的芯片集成了这种通信
