Is there a microsecond delay in HAL library?
HAL_Delay is able to provide minimum 1 ms delay, but when it comes to microseconds, there isn’t any predefined function to create 1 us delay in HAL Library. In this tutorial, I am going to show you how to create 1 microsecond delay in STM32. We will be using one of the Timer to do so.
Do you need a delay function in Hal?
Delay functions are needed in your program, no matter how optimized and fast program you wanna do. I’ve updated my delay library to support milliseconds and microseconds delays. Milliseconds based delay is done using systick timer which makes interrupts every 1ms generated by HAL library.
How to use STM32 to delay microseconds?
STM32 Hardware Timer Delay An alternative way for the DWT to achieve time delay in milliseconds, microseconds, and even nanoseconds (require SysCLK >= 100MHz) is the hardware timers in the microcontroller. You can use one of them to achieve this task.
When to use delaymicroseconds instead of pause?
For delays longer than a few thousand microseconds, you should use delay () instead. us: the number of microseconds to pause. Allowed data types: unsigned int. The code configures pin number 8 to work as an output pin. It sends a train of pulses of approximately 100 microseconds period.
What is the problem with Hal RTC in STM32?
My problem is that the time is not changing over time, the HAL_RTC_GetTime () function is always returning time that was configured at the beginning in the MX_RTC_Init () function generated by CubeMX.
How to create 1 microsecond delay in STM32?
Microsecond/Nanosecond delay in STM32 HAL_Delay is able to provide minimum 1 ms delay, but when it comes to microseconds, there isn’t any predefined function to create 1 us delay in HAL Library. In this tutorial, I am going to show you how to create 1 microsecond delay in STM32. We will be using one of the Timer to do so.
