I cannot get PWR_STOP1_RTC nor PWR_STOP2_RTC to wake up as expected using interrupt mode (WFI).I've tried multiple examples of low power from the L4 examples:PWR_STANDBY, PWR_STANDBY_RTC, PWR_STOP1, PWR_STOP1_RTC, PWR_STOP2, PWR_STOP2_RTC.Standby mod...
Hi all, I just thought I'd add to the list of questions about USB! :grinning_face_with_sweat:I read AN4879 and it says "when the host presence is detected by the device, the device connects its pull up resistor". This is very clear - first detect the...
hey therethere is a simple question: how can I receive data on my UART in DMA mode using RTOS? recently I ran a project where I just get all the data right when they arrived using UART DMA. but not I what the whole process to be done using RTOS. how ...
Hi,In the STM32H7Cube code, There is no LwIP example/Application code for STM32H747-eval. Can anyone direct me towards the same?Or let me know the delta between STM32H743 and STM32H747 LWip configuration.The most important code i need is the ethernet...
Hi,I have a question about STM32G4. I want to exchange data between microcontroller and a C# programm (by usb) on windows. But, sometimes I want to upgrade the program in the microcontroller with this same connection (usb)How I can do this ? I need t...
Hello!I downloaded "Description of STM32L4 HAL and low-layer drivers UM1884" and am trying to learn how to program STM32 Microcontrollers, but the descriptions of the functions are lacking, to say the least. The document even refers to header files a...
Posted on October 20, 2016 at 20:04 I'd like to implement vPortSuppressTicksAndSleep() to put the MCU into sleep or stop mode when there is nothing to do in FreeRTOS tasks. It should be woken up by an EXTI interrupt or RTC wakeup. In my implement...
Hello,I am on a new project that is sending SPI data every 200kHz (real time very important). I work on a STM32F722.I want to use HAL_SPI_TxCpltCallback() to know when the transmit is finished, but I don't want to use the HAL drivers.Indeed, when I u...
Hi everyone !!I am using a virtual com port (VCP) to conect my device to the computer. Everything was running well till i decide to comunicate with a windowns 10 host. I realized two diferent situations :The first was when i started the device with a...
Hi All, I created a test project to Wake Up the device from STOP Mode when it receives data over UART. I ported code from "UART_WakeUpFromStopUsingFIFO" available at /STM32Cube/Repository/STM32Cube_FW_L5_V1.3.1/Projects/STM32L562E-DK/Examples/UART/Ex...
