My data has zeros every 2 bytes.it's like this: 0x55 0x55 00 00 0xaa 0xaa 00 00 0x33 0x33 00 00 ......I want to remove these zeros with address increment feature of DMA.I wrote a configuration for stm32f107 DMA and removed these zeros without problem...
I have a STM32L412, I am using a 3V external reference but my ADC is not very accurate - it never reaches its full value, even though the voltage present is the same as the external voltage. I want to calibrate the ADC to see if it improves the perfo...
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?
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...
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...
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...
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 ...
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...
Hello, Today and for the past days I am struggling trying to setup a TCP/IP server on the STM32F767Zi-Nucleo board.. The IP address is set to :192.168.0.10The mast address is set to :255.255.255.0The gateway address is set to :192.168.0.1 My local m...
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\...
