Hi,I recently bought a Nucleo-H753ZI to test out some of my algorithms that will benefit from the extra compute power. However, I still need to interface with external sensors to read data from it at a very high rate (1kHz). The sensor in question is...
I am running into an issue with the STM32G0B0 MCU: Writing to PD1 seems to result in the opposite value being somehow applied to PD0, even though PD0 is set to input.Effectively, I created a new project in STM32CubeIDE, configured PD0 & PD2 as GPIO_I...
Hi all, Am using STM32L010R8T6 device how to retain gpio state when jumping from main application to bootloader section. i want to retain one gpio pin state from main application to bootloader. How to achieve it. Is there anyway to achieve it. Please...
Hello everyone,So I am trying to take Input from the sensor and then turn on the LED_1/Sound on and another senarove is that whne I prace the GPIO_EXTI1 turn on the another LED_2. but what is hapning is when senser is not givin Input even then LED_1/...
Hello dear All,On STM32G0B1 I'm trying to capture PORTD[0-7] value with DMA on EXTI0 event (PD0 falling edge)(Read PORTD value in EXTI0 interrupt is too slow for this application -> PORTD change value before entering IRQHandler())I configure EXTI and...
Hello,I am working on a project with STM32H753XI mcu and with external interrupts. The problem is that I cannot take an interrupt to PIN PB2. Specifically:1.The Pin is configured as Rising Edge Interrupt (Also tested as falling edge and rising fallin...
I have a timer (TIM10) with a period of 500 us, running without interrupt or any other function.Then I have a rising+falling signal interrupt on PB0 (EXTI0) driven with a 31.25 kHz square wave.In EXTI0 I read the CNT value into a variable New, evalua...
In pins that share more than one GPIO, how do you set the GPIO to connect to the physical pin?For instance, for pins PA12/PA10 and PA11/PA9 one can remap them using SYSCFG_CFGR1 register. But is unclear for the rest of the pins. For example, TSSOP20 ...
Good morning,In regards to the current limit placed on the PC13-PC15 pins of the STM32G431VBx3 that is used as the basis of the STSPIN32G4 (and whose datasheet is referred to multiple times in the STSPIN's), the '431 datasheet has the usual low-power...
Hello,I'm developing an application on the NUCLEO-U5A5ZJ-Q. I need some pins to stay high while the microcontroller is in Stop3 mode.The Datasheet suggests to use internal pull ups, because the GPIO peripheral is not active in Stop3 mode. For this re...
