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 ...
Hi, I'm doing a firmware for a micro STM32F4.The micro is always in an infinite loop in the main(), at the end of each cycle it should check if there are any data on UART buffer, in case there are read all data and continue with the normal infinite l...
I have a requirement for receiving some long USART packets. (200 to 300 bytes). They can be of variable lengths. I did not want to poll or trigger interrupts for each byte and watch for a Stop byte symbol. But been trying to get the Idle line or Rece...
