Can I connect with Samsung SmartThings by using the stm32 board?
I would like to connect Samsung Smart Things using Wi-Fi module on the stm32 board, but I wonder if it's possible.If possible, how should I approach it at first?

Resolved! SPI / DMA / D-Cache
HelloI'm confused about SPI in combination with DMA and D-Cache.I'm using the STM32H743ZI and KEIL uVision CMSIS Driver.In my opinion, the CMSIS driver has a weak point. It only sends data by HAL_SPI_TransmitReceive_DMA() if length is a multiple of 3...
USART DMA misses the input string sequence (Pending DMA)
Hello,I configure my DMA in Normal mode. Here is my code:void DMA1_Channel3_IRQHandler(void){ // USART3_RX unsigned char CheckSum[2]; Var1=Var1+1; if(Var1>1000){Var1=0;} if(Buffer[0]==89 && Buffer[26]=='\n') { Var2=Var2+1...
Dual core STM32H745, runtime contexts assignment.
For peripheral configuration, CubeMX allows me to assign the same peripheral (ethernet, I2C, etc.) to both Cortex-M7 and Cortex-M4 runtime contexts. Say, for ethernet, what does it mean if i assign the peripheral to both? Since i'm allowed to select...
Resolved! Infinite data transmit using SPI
I am testing with STM32F769 Discovery board to make video syncs (not vsync, hsync).I am using SPI module to make infinite clock and data.But, it seems not supported in normal and DMA transmit mode (there is delay between transmissions).How should i ...
Resolved! stm32f4xx_it.c overwirtten if I update the configuration
I'm new to STM32 and am trying to get a couple of simple things working at this point. I am trying to generate and handle a GPIO interrupt on PA0 using FreeRTOS and I have no trouble with that. All the examples I've seen say to modify the ISR at st...
stm32f405RG eeprom emulation
Hello All,I am trying to get eeprom emulation working on a stm32f405RG**. I created a new simple project in STM32CubeIde using the eeprom code from the stm32f4cubeide packages. specifically I am using the code from STM32Cube_FW_F4_V1.25.0\Projects\...
If we initialize an array would it be stored in a different partition of RAM in comparison with the condition under which we do not initialize the array ? initialized array: float Data_Set_X[15000]={0}; uninitialized: float Data_Set_X[15000];
the problem is that When I define the arrays like this :float Data_Set_X[15000]; float Data_Set_Y[15000]; float Data_Set_Z[15000];I get the RAM overflow error which is: `.bss' will not fit in region `RAM' Timer-Blink-Test_CM7 C/C++ Problemwhen I init...
Resolved! Problem using HAL_UART_Transmit_IT
I'm using the HAL_UART_Transmit_IT procedure on a STM32G431 for the LPUART on a 115200 baud communication to a Putty terminal. The MCU is also running ST Motor code.I have some simple 3 character commands that either set variables in the code or read...
RTC not working and not update anythings.
Dear ST; RTC for STM32G0 is not working ( Timestamp Mode ). Could you please check this problem.Best regards.
