I am trying to understand how to setup the microcontroller (STM32F030 in this case) to use external oscillator. I am using blinking LED as a test to see if the code is running. To setup the HSE I did following:selected Crystal/Ceramic Resonator in Hi...
Strange behavior of STM32H743. It continuously reset every few seconds.I check reset reason with this part of code after system startup:if (__HAL_RCC_GET_FLAG(RCC_FLAG_IWDG1RST)) { _PRINTF("RESET_CAUSE_INDEPENDENT_WATCHDOG_RESET\n"); } else...
Greetings,I want to save a variable just before power down. There is PVD feature but it is not supported in STM32F030R8... Is there any other work around for the same ?
Hi,I am asking for some sound technical help on the STM32F769NI BootloaderI am using an STM32F769NI MCU and wish to update the firmware using STs' Bootloader mode via the UART.I am running into problems that none of the UARTs on Pins PA9/PA10, PB10/P...
Hello,I'm using the NUCLEO-F722ZE EVB.Page 155 of the datasheet describes the ADCs characteristics: https://www.st.com/resource/en/datasheet/stm32f722ze.pdfFrom the NUCLEO-F722ZE schematics I see that VDDA as well as VREF+ are 3.3V. VREF- is zero vol...
I'm trying to test the window watchdog timer but when I'm calling HAL_WWDG_Init(), it redirects to reset handler and whole system restarts. Below is my code, I'm showing here only important lines./******************************************/WWDG_Ha...
I'm trying to receive many 24 bits transfers over SPI with no interrupts. SCLK needs to be driven by the STM32. The throughput required would starve out the CPU if any interrupt was needed between/on transfers.From other forum posts, I've seen that t...
Hi,I have a design with a STM32F301 controller. I don't need JTAG, therefore I want to reuse the JTAG pins for other purposes.Is it a problem if the NJTRST signal is toggled when the uC is starting up? Could this affect the uC operation, or does this...
Hi,AN2606 (STM32 microcontroller system memory boot mode) states e.g. for the STM32F301, that in system memory boot mode both USART_TX pins (USART1_TX & USART2_TX) are used as outputs. Is the TX pins really configured as outputs as soon as the system...
