Hello,I have my STM32U575 set to wake-up from standby-mode by the reset button of the Nucleo-U575ZI-Q. Furthermore I want the MCU to wake-up periodically triggered by the RTC. The sample code below just makes the reset button work but the RTC doesn't...
While older MCU needed an EXTI line enabled to allow RTC alarm to wake up the CPU from Stop, for STM32U5 both RCC->APB3SMENR (11.8.44) and RCC->SRDAMR (11.8.45) mention a requirement to allow the RTC lto wake up from Stop modes. No further explanat...
I've taken over this project that is using the STM32h755 CPU. The software is not currently using the Cortex-M4 processor inside the chip. I'm reworking the software so that it will be able to use it sometime in the future. But, until then, I was hop...
I am currently using STM32CubeIDE and want to input an external sine wave. The signal has a voltage of 2.6V and a frequency of 10kHz, and I am using DMA + TIM + ADC. The following is the screenshot of my settings. Currently, I can only capture the pe...
HI, i use CC2 on TIM1 set as input capture measuring pulse period and store in array /* USER CODE BEGIN TIM1_Init 1 */ LL_DMA_SetPeriphAddress(DMA1, LL_DMA_CHANNEL_3, (uint32_t)&TIM1->CCR2); LL_DMA_SetMemoryAddress(DMA1, LL_DMA_CHANNEL_3, (uint...
Hi,We are currently in the process of selecting components for our project, and we have identified the STM32U5A5QJ9 (STM32U5A5QJ), foot-print size UFBGA 132 7x7x0.6 P 0.5 mm) microcontroller as a potential candidate. However, upon reviewing the datas...
Hello,I have a project which demands the device to work in ultra low power mode. I have opted STM32L4R9AI mcu for this project. The problem is i have a spi based lcd display and i need to display the content constantly without flicker even in low pow...
Hi, I have three buttons - START, STOP and CH_SELECT which are serviced using EXTI interrupts. I have also a rotary encoder (A and B pins). Every button line is serviced on a separate IRQ line. Debouncing of the switch and rotary encoder pins is han...
Hello,I am trying to use the quadrature encoder mode of the TIM in the STM32U585VITx, for positioning purposes of a stepper motor movement.According to DS13086, page 79, the general purpose timers (TIM2, TIM3, TIM4, TIM5, TIM15, TIM16, TIM17) support...
HiI want to use a STM32F072 (max. 48MHz) to monitor an external clock.The external clock has a frequency of 38.4MHz.My idea is to use timer TIM3 (32bit) as counter and use the external clock as clock source (external clock mode 1).I read the datashee...
