The documentation notes that FT pins are not 5V tolerant when the output is enabled because that would produce a direct short cut between VDD and 5V.But what happens when there is an external 5V pullup? Is it ok to use push-pull (not open drain) outp...
I'm new to STM MCUs and am trying to start with loading basic binary files (mBed) to my STM32F407VG, but when I plug in the MCU it is not appearing in windows file explorer as a drive, which is a problem since I will need to move my binary files ther...
I am implementing a flash driver on a stm32F767VI. So far the driver works fine until the running with the software watchdog. Of course, the MCU resets on a flash erase to a certain sector.Thanks to the AN4826, I found that I could use the dual bank ...
There is a screen view with a texturemapper and handTickerEvent. I want to use texturemapper to do z-axis animation, and at the same time time and display it through handTickerEvent. However, the timing showed a serious delay.There is some core code...
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...
