Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
As title, MCU:STM32L151RET6, use freertos and enable tickless, when run PreSleepProcessing(uint32_t *ulExpectedIdleTime) function sometimes, cause hardfault. the sleep para is PWR_LOWPOWERREGULATOR_ON. but when use PWR_MAINREGULATOR_ON, it's run OK....
Hello,I am using STM32G4 series controller. I am using Timer 2 channel 2 as trigger source for Timer 4 and Timer 2 channel 3 for PWM generation. Also Timer4 channel 1 is used for PWM generation. First time both the timers Timer2 and Timer4 starts at ...
I am using "HAL_UART_Transmit" and "HAL_UART_Receive" in the HAL uart driver to perform uart communication. While adding the CRC check to the communication protocol, I am wondering if there's any HAL uart driver API that incorporates CRC check functi...
Dear support team,I download recently the last release of Stm32cubeF4 v1.28 and I have the MDK V5.38 installed in my machine, so normally I was expecting that examples will build out of the box but it's not the case.It looks like the project example ...
Hello,I am using the nucleo h755zi-q board on my project. I am having issues with getting the uart driver to work with the LL library. For starters I have the CM4 core disabled via the option bytes and am just working with the CM7. Code for clockConf...
Hi, I want to read flash memory to determine whether or not valid data is in the flash. And if this data can be used in my application. in my code, if I deference a Flash memory address I immediately get a ECCD error. Why is this happening? Thanks,
It seems that, if an error occurs on the last (or only) byte of a HAL_UART_Receive_IT transfer, the HAL_UART_ErrorCallback will not be called until after the HAL_UART_RxCpltCallback - is that right?STM32F0 Cube package.
Hello everyone,I've a project where I'm trying to emulate a mass storage device (MSC) using the STM32F103C8T6. The data itself should be stored on the Serial NOR-Flash (Winbound W25Q64...), operations are done with this library. Using the library in ...
HiI successfully got the USB DFU bootlader working in 2 hours.This one: https://www.youtube.com/watch?v=n_LDXOQHerUNow i would like to add some encryption to it with a time budget of couple of hours.I am already using python for USB DFU update.What i...
HiI have a sensor board with USB MSC and an EMMC memory chip. Under windows every thing works fine but not under MAC or Android.I am using FATFS and format the card with fomat option = #define FM_ANY 0x07.Does any one have a clue what is going wrong?...
