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 there;I have been trying to get analog signal from three channels on my STM32 for 2 days. I could get the signal from each potentiometer using polling with single channel conversion, but when I try to use multiple channels with DMA, all I get is z...
page 1320; timer 2 input pwm mode"1. Select the active input for TIMx_CCR1: write the CC1S bits to 01 in the TIMx_CCMR1 register (TI1 selected).2. Select the active polarity for TI1FP1 (used both for capture in TIMx_CCR1 and counter clear): write the...
I aim to set the IWDG (Independent Watchdog) to STANDBY mode to ensure that our MCU remains in that state without being awakened by the Watchdog. To achieve this, I utilized the following command with STM32_Programmer_CLI.exe:After executing the comm...
My STM32F0 won't show up under "Ports " in my device manager. It does, however, show up under "Universal Serial Bus Devices". I'm trying to print to a serial monitor. I've spent over 12 hours (low guess) trying to troubleshoot this issue. Here is wh...
In RM0351 Reference manual Figure 420. USART block diagram, the positions of shift registers and data registers (of both Transmit and Receive) are wrong; their positions should be swapped.
Hi Guys.I want to send data to UART using DMA. Every 3transfers I want to generate another DMA request to transfer data from the timer CNT register to memory. The documention of the DMAMUX is basically impossible to understand. They have lines and si...
Hello,I have 10 devices STM32L496VG in Dual-Bank-Boot mode with the identical firmware in BANK1 and BANK2.In 5 devices is booting from BANK1 enabled (BFB reset) and in the other 5 devices is booting from BANK2 enabled (BFB set).I would expect the sam...
Hi All, I just got NUCLEO-H503RB for I3C. And tried to download the image that I built. (just followed the link's instruction)https://wiki.st.com/stm32mcu/wiki/Getting_started_with_I3C and I just realized it needs ST-link to run and debug my codes. B...
Hi ST!I am writing to ask if any ST MCU's will be released with 2x independent FMAC units?At the moment, doing stereo audio processing with a single FMAC is problematic (and ST MCU's ONLY have a single FMAC unit), especially being unable to load the ...
