Good afternoon,I have a problem interrupting the TIM3 Timer, I inserted an output pin to make an alternation but no oscillation appears on the pin.Source code attached.I compared it with other examples and in my understanding everything seems to be f...
Is it possible to use the ITM or to get debug message from the stm32g051 using the PEmicro multilink universal? I try to insert this code but aparently there is no CoreDebug on the stm32g051g8. Thank you.
I was trying to interface W25Q256 with STM32H563ZI in QuadSPI mode as i have done with normal SPI it was working fine as i need to operate at higher frequency than normal spi for continous read and write operation. I tried to read Device information ...
The issue I am having is as follows on the STM32G051C8T6. We are using the internal RTC with Vbat pin. On this MCU Vbat can be internally configured to be read by the ADC by diving by 3 Bridge. We have ADC Setup, I am making sure we perform the ADC C...
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...
