Heyho, just checked the build analyser in STM32CubeIDE for my L031 project and found "impure_data" in the RAM list.Can anyone please explain what that is? Google didn't really help... Just curious, RAM size is not a problem for this project (32kB fla...
I am using TIM1 Channel 4 to generate a PWM signal to control a servo motor. My goal is to achieve speeds from 0 to 3000 RPM by increasing the PWM frequency every 1 ms (acceleration).To achieve this, I calculate the ARR and PSC values corresponding t...
Hi,I am facing an issue with my STM32L562E-DK board. Initially, I was able to debug it using STM32CubeIDE. However, after attempting to configure the controller in UART boot mode, I accidentally enabled read protection (DC:LEVEL 1). Since then, I can...
I am using the STM32H745I-DISCO board, where Core M4 handles SDMMC and FATFS, and Core M7 manages USB Mass Storage Class (MSC). Is there a procedure or any available documentation on linking both cores for seamless data sharing?
Hello!In STM32H503RBT6, PIN 16 (PA2) can take the role of a UART or ADC.In my application, hardware-wise, it would be ok continuously change their role (every 500ms).What about firmware?I'd like to set it to 1-wire UART, do some communication for aro...
On our custom board using STMH745IIK6 we cant use both PC3_C and PC3 pins together. PC3 is configured as ADC reading 1.7V and PC3_C is configured as SPI MISO and when configured this way we cant read SPI device (I3G4250D) also ADC reads corrupt as we...
Hello, I am creating 2 pcbs, one for controlling 6 stepper motor drive boards, and one for controlling 8 servos. Both have an STM32 and CAN communication. It would be great if you could critique my designs and tell me where I could improve so they ha...
Hi there!I have two UART devices connected to STM32U575 that run at 1.8 and 3.3V and 115200 baud rate. I am trying to get USART1 working on STM32U575 on PG9 (TX) and PG10(RX) that uses VDDIO2 reference 1.8V and UART4 on PA1(RX) and PA0(TX) that uses ...
I'm using the STM32G030FP6 in standby mode with WKUP2 for wakeup and the system has a backup battery. I'm facing the following issues:When using the LSI clock, standby entry and WKUP2 wakeup work normally.When using the LSE clock, after entering stan...
I am running code on an STM32U585QI that enters STOP2 when the code is idle. I am disabling the data cache before going to stop2, and enabling it when coming out (to deal with an errata item). My code basically does this:HAL_DCACHE_DeInit(); HAL_P...
