stm32 GPIO Configuaration

I am using a pin to Switch on the power supply once the MCU is powered.When powering up the MCU I am getting a Glitch before it turns on the MC GPIO configuaration is given below. For every output I am getting a glich before it SET from RESET Can a...

Resolved! FDCAN behaving differently on two identical stm32h735g-dk boards runnign the same code.

Hello,I am running the code as shown in the attached file and I get two different behaviours on to identical stm32h735g-dk boards. One of the boards will send exactly 37 can messages when the button for master is clicked and the other board will send...

Resolved! STM32L476RE output characteristic impedance

Hi team,I am currently developing a board with the STM32L476RET6. This project involves UART communication (UART4, PA0 and PA1), and I am concerned about EMI due to the fast rising and falling edges of the TX signal. To address this issue, I am imple...

STM32U5A5 GPIO state change on Stop2 mode enter

I am trying to figure out why the state of GPIO pins are changing after entering Stop2 mode. I've got an ADC chip connected with Reset lines being held high by GPIO pins configured as push-pull with pull-ups enabled. When the device enters Stop2 mode...

Resolved! STM32L412: can't toggle PD2 on a custom board

Hello, Am working on STM32L412RBT6. We made a custom PCB for our product and Am trying to PD2 as digital output as toggle function. I can't able to find any high output at PD2. The pin PD2 is always remains low. Please help me on this

ETM trace maximum data rate on STM32U575

Hello everyone,We are having trouble getting tracing to work with our target at full clock speed and would like to understand why, we have an application running on STM32U575 @ 160MHz CPU clock, we also connected the J-Tracer to it using a connector ...

Resolved! What are the applications of open drain GPIO configuration.

Hai All, We can configure a GPIO pin either as a Push-Pull or Open-drain configuration. Can anybody explain briefly, what are the applications of Open Drain configuration?
