We have configured TIM2 Channel 1 to capture rising edge on PA0 pin.We have enabled DMA1 Stream5 to read data on Port D and copy to local array.The callback function for DMA1 is not triggered.Please let us know, if we are missing any configuration.No...
Hey, I made some simple code for my STM32L053C8 Discovery kit to toggle GPIO pins which are connected to LEDs. I used PA0 PA1 and PA2 pins and only PA0 pin responded. Then I turned all GPIO pins high and using LED found some more pins which didn't tu...
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...
