If "Enable Update Interrupt" is not selected in the case mentioned above, the Update interrupt will not be generated, and consequently, the LED will not toggle since the update interrupt is disabled. When the sample time of the constant block connected to the timer block's UG (Update ...

This library enables you to use Interrupt from Hardware Timers on an STM32-based board, such as STM32F/L/H/G/WB/MP1.As Hardware Timers are rare, and very precious assets of any board, this library now enables you to use up to 16 ISR-based Timers, while consuming only 1 Hardware ...
This is an interrupt handler. The HAL libraries will manage the main interrupt service routine (ISR) when the timer interrupt occurs (feel free to examine it in stm32l4xx_it.c). At some point in that ISR, the code will call HAL_TIM_PeriodElapsedCallback(), which we ...

STM32CubeMX 查看 timer10 频率 stm32频率检测 一、STM32 IO中断方式测试频率有要求,频率不能过快,目前测试2M没问题,频率过高中断触发就处理不过来。 二、过快的频率得先降频,用D触发器对频率进行降频,如下图所示,2、4、8、16分频,此例用2M时钟进行测试,对2M时钟进行2、4、8、16分频...
我们可以打开 MDK-ARM 工程,在左侧 Drivers/STM32F1xx_HAL_Driver 文件夹的 stm32f1xx_hal.c 文件中找到 SysTick 的初始化。/** * @brief This function configures the source of the time base. * The time source is configured to have 1ms time base with a dedicated * Tick interrupt priority. ...
void timer0() interrupt 1 { TH0 = (65536 - FOSC / command_speed / 1000) >> 8; TL0 = (65536 - FOSC / command_speed / 1000); /*multi_timer计数器自增*/ timer_ticks(); } 4、程序编译与固件生成 我们看到编译过后,整个程序的大小仅占用1.3K多,确实够轻量!接下来将生成的.hex文件下载到...
有人使用STM32G4系列的通用型TIMER基于捕获功能对外来信号进行周期及占空比的测量。他用TIM3产生频率、占空比可调的PWM输出做为被测信号。TIM4用来进行频率测量,工作在复位从模式,被测信号接到其通道2的输入脚。然后经内部边沿检测和内部滤波电路后,兵分两路分别连接到IC1和IC2。显然IC2使用直接输入模式,IC1使用间...
