STM32 时钟输出MCO功能 一、数据手册: 使用步骤: 1、开时钟输出时钟控制; RCC_MCOConfig(RCC_MCO_SYSCLK); // 实际是对RCC_CFGR寄存器的24-26位配置。 2、配置时钟输出管脚PA8为复用推挽输出 GPIO_InitStructure.GPIO_Pin = GPIO_Pin_8; GPIO_I... ...
The reason each pin is allocated to 4 bits is because there are 16 possible alternate functions for each pins (even though this bits are simply reserved). So each of the pins can be placed in any 1 of 16 modes to determine what alternate function a pin will have. Since each pin is ...
Adding to the configuration complexity, many SoCs multiplex multiple dedicated functions to a single pin. It is common to see devices that have as many as six or more functions multiplexed to a single I/O pin. An example of this multiplexing can be seen in section 2.2 of the KW41Z ...
ISR routine is just like any other C function which the hardware call the name for these functions can be found in the startup file of stm32 project which gets auto generated and is provided by ST . Names of ISR handler for GPIO interrupts Pin NumberHanlder Name 0 EXTI0_IRQHandler 1 ...
I'm getting familiar with QSPI on my STM32F746-Discovery (not really relevant for the question, just some context). While reading reference manual, it lays out in details how the peripheral functions (insert rant over the peripheral being called QSPI and QuadSPI here). In every communication...
