I have implemented an emulated UART on STM32F2 using the sample program from STM32F4. The UART TX data output is correct. Until a HAL_Delay(100) is add. When added delay, the UART TX output appears corrupted as shown below. Why is the HAL_Delay affec...
When I am trying to login to Unicleo GUI I am able connect to the communication port but the firmware description, version, expansion board name and library version in the login screen is showing unknown as I result , i suppose, am not being able to ...
After doing debugging i have found that the error code is set by DMA config function :HAL_StatusTypeDef HAL_DMA_Start_IT(DMA_HandleTypeDef *hdma, uint32_t SrcAddress, uint32_t DstAddress, uint32_t DataLength) { . . . . . else { /* Process...
Hi,I am a new coder using the STM32L100RC discovery board. As such, my problem is quite simple I believe; I cannot exit Stop mode using an external trigger on the WakeUp Pin PA0. The code works as fallow: the LED on the PC9 pin light up, I enter STOP...
The Wakeup works fine with temperatures above. At a unit based limit the wakeup does not accure (only watchdog as fallback). RTC remains running.Any ideas?
Hi Everybody,I have an issue with STM32L433CCU6, when it's entering or exiting STOP 1 mode at temperatures from -36dC to -29dC uP completely freezesBasic overview of program:watchdog is set to 25 secondsclock: HSE 8MHz -> PLL 16MHz (SYSCLK) -> /2 -> ...

Hello. Never had parcing string experience so maybe it is a simple question.I will get from GPS module message like this:+CGNSINF: 1,1,20190913183507.000,54.000000,25.000000,139.107,0.00,87.5,2,,0.6,1.1,0.9,,12,16,,,51,,I need to extract data in corr...
hello, I am using L031K6 with UM1956 board.I am trying ultra low power sensor project with it. I want to use this board in disabling USB serial communication port status. because I think it is spending a lot of battery, even though the CPU is in the ...
