STM32 devices have RTC (Real Time Clock) built-in, which can keep the track of the current time and date. RTC can be used for chronometers, alarm clocks, watches, small electronic agendas, and many other devices. Today in this tutorial we will see how to access internal RTC in STM32...
However, in the temperature range of -40 to 105°C, the accuracy decreases. To compensate for the influence of temperature on internal RC oscillators accuracy, the STM32G0 series microcontrollers have built-in features to allow users to calibrate the HSI16/HSI48 oscillator, and to...
2.Peripheral overview↑ TheNVICperipheral is theArm®Cortex®-M4 andArm®Cortex®-M33 interrupt controller. As a result, it cannot be accessed by theArmCortex-A7 core orArmCortex-A35 core. Refer to theSTM32MP15 reference manualsandSTM32MP25 reference manualsfor the complete list of feat...
AN4736 Application note How to calibrate STM32L4 Series microcontrollers internal RC oscillator Note: Introduction The STM32L4 Series microcontrollers have two internal RC oscillators that can be selected as the system clock source. These are known as the HSI16 ...
Overflow interrupt, to detect when the internal programmable counter rolls over to zero. Functional Description Shown below is the block diagram of the embedded RTC for a typical STM32F10x microcontroller. The RTC comprises of two major components. The first is the APB1 bus interface. The APB1...
An easy way to measure the framerate is to use the HAL_GetTick() in the interrupt handler: stm32f7xx_it.c volatileintlast=0; volatileintdiff=0; voidLTDC_IRQHandler(void) { /* USER CODE BEGIN LTDC_IRQn 0 */ intnow=HAL_GetTick(); ...
This page is for anyone to report an Internal Error ("Internal Error:" in GCS or DataFlash messages). This allows the Dev team to be alerted, and to investigate as soon as possible. Please enter the firmware used, vehicle type, and the Internal Error message. If you have a log, pleas...
