When a GPIO pin is connected to power an external device via Magnetic switch, from the STM32 point of view how does it know if the Magnetic switch is ON/OFF? ON -> Device is powered ON similarly OFF.Can STM32 detects change in current on GPIO pins?A...
Hello,I have some questions relating to STM32L4R7ZIT and the different ways to enter/exit low-power modes or to power cycle, in both cases without losing RTC and backup registers.VBAT is always powered. There is an LSE.I need to understand which boot...
Stm32f469 is currently developing the product using TouchGFX. The problem is that when the screen changes, the picture sometimes disappears. I thought there might be a problem with QSPI communication.QSPI believes that there is a memory-mapped mode t...
Hi all,I am using STM32L431 and the device is not waking up from STOP mode with an RTC alarm interrupt. Can somebody pinpoint where my issues are?My configurations in the code configurator:I am enabling the crystal oscillator, enabling the calendar, ...
I want to transfer binary data (not character) without having to worry about character conversion, so directly:uint8_t data = 0xBF;HAL_SPI_Transmit(&spi1handle, (uint8_t *) data, 1, 1000);But I get something else at the receive end, specifically I ge...
I need help with standby mode and rtc wakeup.If I set date/time and RTC-Alarm time, I don't get an RTC - interrupt.I guess this is why the stm32f103 don't wake up from deep sleep.Do anyone have an link (or code) to an example using RTC amd wakeup fro...
I have two custom boards with one STM32F746 each. Both MCUs run identical code (in different projects with potentially different configuration).One MCU runs as expected, but the other MCU throws a HardFault as soon as MX_NVIC_Init() enables EXTI int...
I connect with the module to an Access Point and get IP. Now I have some devices connected to the same Access Point. I want to receive UDP packets from the devices.What should I do? I can connect only with TCPif (WIFI_StartServer(SOCKET, WIFI_TCP_PRO...
