I have an application where I want an external input logic signal to capture a Timer counter value. In my situation the timing measurement is critical so I'm thinking of having the input signal trigger a Timer counter value capture and set a DMA inte...
EE designed the board with both pins in use and both needing to wake up from STOP2. At start PA5 must be used to awake. Once awake, switch interrupt to PB5 for normal processing. When normal processing is done, switch back to PA5 and enter STOP2. ...
Hello, I'm using a stm32h745 on my new board with an external 32768Hz quart and setup RTC at startup as follow (using LSE):HalErr_tError HalRtc_Init(void) { HalErr_tError zError = HalErr_eNoError; /* Configure RTC prescaler and RTC data regis...
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...
