I am using a STM32U031 part with register level configuration (no Cube libraries). The Timer should be straight forward to start in a single-shot mode but when I set the LPTIM_CR_SNGSTRT flag in the CR register, the CNT register never increments and ...
We are using STM32L053R8.What is the best method (Clock and Low power modes) to achieve lowest power consumption while taking ADC reading every one second? Also whether to use RTC or LPTIM or combination of both to wakeup the device from the Low Pow...
Let me start by saying:Yes I know the STM32 Finder exists, no it doesn't help me find what I needYes I've seen this thread but I do not want to get into manually coding a script to try and find parts if I can avoid itYes I have used the CubeMX and no...
During transmission and reception using STM32U585 LPTIM+SPI+LPDMA, noise to SPI3_SCK causes a fatal bit shift in the bitstream. The condition on the left is normal and the oscilloscope waveform can be received exactly as expected.However, if you intr...
Microcontroller: STM32L051R8Tx (MSI used as system clock, set to 4.194 MHz) Board: custom design (no Nucleo etc.)The LPTIM1 is clocked by an external LSE (32,768 kHz, +- 10ppm).IDE: Keil uVision V5.36.0.0Compiler: ARM Compiler “Use default compiler V...
Hello,I am using STM32U575 and would like toimplement a PWM output. This should also work in Stop2-Mode.Clock for the LPTIM is LSE. It works with LPTIM1 and 3 without any problems.To generate a PWM in Stop2-mode, I use the LPBAM with LPDMA. Now I wou...
Hi,uC: STM32G051K8U6, IDE: 1.14.1, MX: 6.10.0-RC9I tried to generate some low frequency timeout using the LPTIM1 and the internal LSI time source, but it seems the code generator doesn't take in account the chosen option in the "LPTIM1 Clock Mux" sel...
I have an STM32G071CBTx with a rotary encoder wired to GPIO pins PB5 + PB7 (LPTIM1_IN1 and LPTIM1_IN2), but for some reason it will never count down no matter which way the encoder is turned.I have checked the encoder waveforms and they are as expect...
Hello, For my research work I want to characterize how much current the LPTIM of a STM32U575ZIT6Q consumes when in compare match mode (counting from 0 to 65535 repeatedly).I prorgrammed two very simple codes, one where the counter is not initialized ...
I have the low power timer LPTIM1 working on a STM32H7A3 but the way I have to clear the IRQs is a little confusing. Here's my IRQHandler:void LPTIM1_IRQHandler(void) { //Disable LPTIM1 CLEAR_BIT(LPTIM1->CR, 0x01); //Clear IRQs LL_LPTIM_ClearFl...
