you actually don’t need to check their status manually. As long as you enable the interrupt by calling HAL_NVIC_EnableIRQ(), the timer will automatically trigger an interrupt handler function when the event occurs. You can look up the interrupt function name in the startup_stm32xxxx.c ...

This technique consists of different sequences and patterns that are scheduled in each of the 8 repetitive burst periods. This design flexibility can be achieved with the features of the 8/19 DocID026292 Rev 1 AN4885 Application description embedded high-resolution timer of STM32F334xx device. ...

1. Set one timer for each encoder in up counter mode; sample the count value at a known rate using another timer interrupt and calculate the average period over the sample time. This would be set up so all six counters were polled and calculated at the same time. My understanding is ...

Why do we need this STM32_TimerInterrupt libraryFeaturesThis 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 ...
我们选择了36-pin, 72 MHz的STM32 (STM32F103T8U6), 足够用于产生黑白视频信号和点信号,同时还使用了一些定时器和SPI(在这种方式下更新帧缓冲是自动完成的), 在400*200分辨率的显示器上VGA输出视频信号看起来还是比较可观的。 使用的材料: 1 STM32F103T8U6开发板一块(或者同类型的开发板)。我们使用的是AK-STM...

In order for software timer mode to work, you need to add a call to yourloop()function to process ticks. For example, voidloop() { uClock.run();//do anything else you need to do inside loop()...//you can intercalate your main processing with other uClock.run() calls to avoid...
