Hi all, I have already searched on the forms and in general did not find an answer to my problem, I will be very grateful to you for help.I need to create an output signal with a frequency of 100 Mhz as CLK in STM32H745. I used the Discovery Boards ...
stm32g474ve , dma can be triggered using external interrupts, but dma cannot be triggered using software. In theory, both external interrupts and software interrupts should trigger events. At the same time, I have verified that stm32h750 is OK. So ...
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin){ if(GPIO_Pin == LVMS_DETECT_Pin) { HAL_GPIO_WritePin(AMS_LED_GPIO_Port, AMS_LED_Pin, GPIO_PIN_SET); HAL_Delay(2000); HAL_GPIO_WritePin(AMS_LED_GPIO_Port, AMS_LED_Pin, GPIO_PIN_RESET); }}When the trigg...
Hello,I am using a bog standard, new, out of the box Nucleo-wba52cg.For some reason I can't get PA8 aka GPIO_23 to pull lower than about 1.6V?I discovered this when running the TIM_OCToggle example program. TIM_OCToggle uses TIM2 to toggle pins on e...
My project uses multiple different GPIO's configured as EXTI interrupt sources, and there is a point where, after calling the API:HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFE)Some different instructions should be executed depending on which EXTI rising...
Dear STM team,do you consider to add "Programmable IO" (PIO, as in RP2350) or FlexIO (as in NXP MCUs) to your chips?It would be really cool: often I need interfaces on MCU which are not available as a peripheral devices, such as: MDIO (Master), JTAG ...
I tried to solve the questions that occurred during the development of STM32 L4 Series through Googling, but I couldn't find anything related, so I'm leaving a post. I understand that even if the built-in Pull Up or Pull Down circuit is enabled, ther...
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...
I can not find any instruction in documents about gpio configuration in alternate function mode. For example I want to configure SPI GPIO. Examples found in the internet have different configuration. Is it unimportant to configure push pull and pull ...
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...
