I'm using an STM32H725ZE chip. I know that PA15 defaults to JTAG pin JTDI, but the datasheet for the part specifically says this:In SW-DP mode, the unused JTAG lines JTDI, JTDO and nJTRST can be used for otherfunctions.I'm in SWD mode because it's a ...
Hi I am programming a STM32L433 and have the processor wakeup from Standby mode. The first thing it does after wakeup is check the cause of the wakeup, and if RTC increase the time, do a few readings and go back into Standby mode. When I am running ...
Posted on May 03, 2016 at 00:19I have a digital input GPIO line where I need an interrupt whenever its input changes. In STM32CubeMX I set this pin to an EXTI line and set the interrupt to trigger on both rising and falling edges. When, in response ...
Hi,I want ot use the UART bootloader to program a STM32G070RB (with the Nucleo board). I've used the following code to activate the pin Boot0 to access the bootloader (some of it may be useless):while(FLASH -> SR & FLASH_SR_BSY1); FLASH->KEYR = KEY1;...
In LPLTIM_IER register, the ARRMIE bit is SET by software and LPTIM_ISR register the bit ARRM bit is SET by hardware but this LPTIM4_IRQHandler() function is not calling. what might be the reason of not calling this function LPTIM4_IRQHandler() ?
Hello ,I recently bought the STWIN.box core system board (STEVAL-STWBXCS1), so I don't know everything about it. I would like to carry out a predictive maintenance project. I followed the steps below:1- flash the binary file with STM32CubeProgrammer2...
I have enabled two interrupts. First one is EXTI for GPIOA0 Pin and another is UART3 for RXCALLBACK.I want to disable EXTI interrupt when UART interrupt is triggered and enable again EXTI interrupt once the task is completed.I used __disable_irq(5) ...
I've generated a CubeMX project for a mass storage class device and can't seem to get the OTG_FS embedded pullup on DP to engage. I've enabled VBUS sensing, and can confirm that the code initially does a soft disconnect (OTG_DCTL->SDIS = 1) then a co...
Here my new code to use encoder with STM32First search on datasheet 2 pins with TIMx_CH1 and TIMx_CH2.In my case was a STM32F469 and I have used PC6 and Pc7 with TIM8_CH1 and TIM8_CH2.After search in the file stm32f4xx_hal_gpio_ex.h the relative AFx ...
Hiwe are working with a STM32H7 project. Recently we upgrade the packages and the Keil.STM32H7xx_DFP.2.5.0 grow up to DFP 3.1.1.Since the upgrading, the SPI start to fail (some data bits were wrong in every reading). Downgrading to DFP 2.5.0 it works...
