I want to set a RTC alarm to trigger 1 hour from now but there doesn't seem to be a built-in function (using HAL) to add time. Of course 1 hour in the future is easy unless it happens to be almost midnight or worse almost midnight at the end of the ...
Hello guys, I previously asked the question about the UART interrupt but not get any reply. Currently am able to receive data from uart interrupt but not able to clear the buffer to get new data. please help. my code is void USART1_IRQHandler(void) {...
Hi, I am running an application on the STM32L562-DK. The performance of the application is lower than anticipated. I started investigating what could be causing the performance issues. I found some example projects that had hal function calls to e...
Hi All,I would like to install stm32 vcp dirver (version 1.5.0) silently, without asking any user interaction. I tried to start VCP_V1.5.0_Setup_W8_x64_64bits.exe with \S switch, in this case the installer is started, but it does not finish the proc....
Dear,These 2 functions are almost the same, the difference is the const DMA_FLAG_TCIFx and DMA_IT_TCIFx. However, when AND with the RESERVED_MASK (0x0F7D0F7D), it becomes the same. This also happens with EXTI_ClearFlag and EXTI_ClearITPendingBit.For...
Has anybody worked with MAX31865 PT100 sensor chip. I have a module with that chip on a STM32F746 board and SPI bus gives me only zeros. Local loop MOSI->MISO works. The chip doesn't look very complicated but I get nothing out off it. The module has ...
In our product we will be placing one of 3 different processors. I have developed code to determine this by evaluating the registers for the peripherals, but I'm wondering if there is another way.I've been looking at the DBGMCU_IDCODE register. And o...
Hi!I'm working in a project that uses flash memory to store calibration data. At the first power on (before writing data in flash) everything works fine. After calibration, if I turn off the board and turn on again, my USART2 stops working (only send...
I'm having trouble getting the on board SD card reader working properly. The board is the STM32H735G discovery kit. When attempting to mount the disc it comes back with error FR_NO_FILESYSTEM. A closer investigation shows that when reading the first ...
