I am using one of the 32 bit timers to measure intervals for fault protection on a HV pulse modulator. I have an interrupt on EXTI that captures both leading and trailing edges of the command pulse. In the service routine, I simply store the lates...
My simple program to test wake from standby with PC13/Wakeup_pin4 is working. I use the pushbutton on this pin as an EXTI and had to add the GPIO_DeInit before setting the pin as an input without EXTI.The same code does not work in my larger program...
I’m working on a design where I need to communicate with two SPI devices that operate at different logic levels:1) A sensor running at 1.8v logic (need SPI + 2 other lines, all at 1.8v) 2) Everything else on my board, preferably running at 3.3v, I wi...
I have measured the MCU current on the NUCLEO-L433RC-P dev board by removing JP6 and connecting a multimeter. The current in shutdown is ~1mA, why is this so high ? The shutdown current should be nA or uA at most... To shutdown I call "HAL_PWREx_E...
Hello again, The DMA now works in standard request mode with circular mode disabled, but it doesn't when I am trying to use circular buffering mode (my destination buffer only contains 0s). I defined manually the data size, the source and destinati...
Hello All, I am using STM32L011G4U6TR for one of my application development. I have written a code where I am using,11 GPIO, 1 UART and Internat EEProm.When I am building the code in I am getting below Error and not able to load the Application on ST...
Hello All,I have a camera of 5 MP and optical light engine with display of 1280 x 720 pixels.Can I run both the peripherals on MIPI interface simultaneously such that the camera content is input/feed is input to optical light engine having display of...
Hi, we have perform a series of environment test for STM32H533, including thermal cycle and vibration test.Durting vibration test, DUTs are powered off, while under thermal cycle test, DUT is powered on.After the test, all application part still func...
Hi, I hope this is the right place to ask. I'm currently working on interfacing an SD Card with a nucleo f767. I used the DS-Bits in CR2 to set the data frame to 8 Bit (what also should be the reset value). Despite that, MOSI always sends the whole d...
Hi, We are using STM32G491 Series MCU in our application.Can all the three I2C lanes can be used either as a master or slave.Is there any specific pins which supports only as a master or only as a slave. Warm Regards,Mythili B
