Hi could somebody please help me with this: i am a beginner ,i have set the Timer_init and Gpio_init with bare Metal i'm working in STM32F429ZIT and i'm aiming to control GPIO pins PG13 and PG14 using the PWM channels with two channel each for every ...
Resolved! Speculation on STM32F767
Hello, I'm studying the STM32F767 MCU, and I noticed that in STMCubeIDE is possible to configure if the speculation is permitted, but I didn't find an explanation of this feature. If I set Speculation disabled, do I set the flash strongly-ordered? Do...
Resolved! Issue After Bootloader on STM32F072RBT6: Stack Pointer Not Jumping to Application Address
Dear STM32 Community, I am currently working on a project using the STM32F072RBT6 microcontroller, where I have implemented a custom bootloader to load an application program into flash memory. However, after the bootloader successfully writes the ap...
Resolved! STM32F429 GPIO 5V tolerant IO behavior
Hello,i use at a STM32F429 the PD5 pin to drive a PNP BJT transistor to switch a sensor supply:PD5 is configured as open drain, and when the stm32 is pulling PD5 low, the transistor supplies the sensor with 5V power. This works so far.But when PD5 is...
Resolved! STM32U575 SRAM data retention in Standby mode
Hello,I am trying to make a program in which the micro stm32u5 is stored in ram memory some data after activating the Sleep Mode.For this I have defined in the flash file the SRAM2 memory that is supposed to be in charge of this and I have saved it ...
Resolved! STM32H753XIH6: issue with pins F1, F2, G2
Hi,I am using STM32H753XIH6 in a new design. The PCB is already manufactured, ready for the assembly. The issue is that I mistakenly designated the pins F1, F2 and G2 as NC in my schematic library model, but realized that the datasheet says they shou...
STM32H7 gpio speed problem
Hello everyone,I am encountering difficulties with a project. I decided to use an STM32H7B0 microcontroller, which I had previously used in other projects, for a new application. However, I have encountered a difficulty due to the signal propagation ...
Resolved! SDIO port with 2 SDCARD Chip Select
Hello, I have a STM32F411 and I am ready using the SDIO port, I would like to connect 2 SDCARD to the SDIO port and be able to switch from one to another like using a CS Chip select GPIO. Is it possible ? how would I do that ? Thanks Vincent
STM32U575 Analog Watchdog with Oversampling on ADC1. Need clarification of the reference manual
Hi,One of our project is using the STM32U575 and we use the ADCs analog watchdog feature of the CPU. At the beginning of the project, we did not used the ADC oversampling, but for stability and reliability purpose, we have turned on the ADC oversampl...
