Dear Sir.Using stm32u585 , The external clock on OSC32 pins is 32.768 Khz.I need to config LPTIM2 to run on 32.768 Khz with no success .How do I configure the SystemClock_Config() to make LPTIM2 to run on 32khz.Attached a code/** * @brief System C...
How to give the STM32L4 series LPTIM1 timer an initial value,It seems the register address is closed to the public
I create new StCubeIDE project base on NUCLEO-U575ZI-Q EVB.Set LPTIM1 as "Counts internal clock events" mode and enable interrupt, set clock source to "LSE".Did some simple modification in main.c to verify it:Add #include "stdio.h"Overwrite weak func...
In the code:adcbuf[1]=1; noise_buf[1]=4; uint32_t hal_status = HAL_OK; static uint32_t buftransit = 125; buftransit=2; noise_buf[2]=buftransit; HAL_LPTIM_PWM_Start(&hlptim3, 0XFFFF, 0X7FFF); HAL_DMAEx_EnableMuxRequestGenerator(&hdma_d...
I have two code (but both in buffer transfer mode), with different behaviour of MDMA buffer transfer, In software request mode each buffer element of block transfers in each request but in hardware request case (LPTIM3) each request causes MDMA to tr...
The file has been appended. If the program runs well we must be able to see rng_temporary is changing. But it does not change from zero. Device is STM32H743VIT6 rev V. on STM32cubeIDE 1.10.1I've also tried to run it with dma transfer complete event b...
The output pin in question can be configured as LPTIM1_OUT and I know how to configure the LPTIM1 but I'm afraid I'll endup with LSE/2 as a clock. I need the LSE clock source to be connected to that output pin 1:1.Besides using the LPTIM1 isn't there...
I am using LPTIM for periodic ADC reading (every ~250ms) and periodic IWDG refresh. CPU should go to Stop mode when the ADC value is under certain value. If the ADC value is over certain value then CPU should reset end continue in Run mode. ADC is cl...
I am trying to create a 50ms timer using the above reference. The clock is 16MHz, I have a divisor of 16 and have the NVIC enabled (all this is done in cubeMX). I have the following ISR void HAL_LPTIM_AutoReloadMatchCallback(LPTIM_HandleTypeDef *hl...
What is the max frequency when driving the LPTIM from an external clock?I would like to drive the LPTIM1 from a STM32L433 to control a Boost switch regulator. Since we can clock LPTIM1 from 80MHz PLL internal. Is this limit safe for external as well?...
