I measured the time took to run a length 127 Multiply–accumulate routine by togging a GPIO pin before and after the arm_dot_prod_q15() routine. And then I can measure pulse width by a scope. It was 7us on the STM32F413 and 6us on the STM32H7A3.
I have several eval boards and was interested changing to ST platform prior to pandemic. Now looking at getting back to it, but checking with Mouser, Digikey, etc.. and nearly all of the STM32F4... parts I would be interested in using are still out ...
Hi,I am working on a project with STM32G431C8U6. My code always goes to HardFault Handler. I created a new project for testing my MCU just an easy code, code went to HardFault again. I share my ScreenShoot's please help....
I understand that there's a great deal of copypasting when creating RMs, but can ST please pay more attention to the details?In particular, no part described by RM0394 should have SAI2 implemented:yet there are references to SAI2 through the document...
Hi, I am trying to set up simple example project with DMA and triple adc working together. What I am getting is that DMA interrupt is only activated once - I verified all the data is trasfered as supposed to. But, next time I start ADC in the for loo...
Hello,I'm working on a STM32 project which use the timer in encoder mode.TIM2 of my STM32F103C8 is set in Encoder Mode, I've enabled the TIM2 global interrupt.I'm evaluating the counter at each interrupt.Prescaler is 0, Counter Period is 65535.Main c...
Hello.I'm having some issues while trying to acquire a simple ADC value. I'm using a single channel ADC with DMA enabled.My MCU is the STM32F030K6Tb and i'm using a custom board.I'm trying to use ADC to read stable and continuous battery voltage. To ...
Stm32h747i discovery kit comes with an 2mb flash memory, I am trying to run an example project which is pasta detection based on this blog AI:How_to_use_transfer_learning_to_perform_image_classification_on_STM32but after some how after flashing the c...
After some experimentation with using the timer trigger with an ADC multichannel scan going to DMA I've found that I can only get most configuration working by setting the DDS bit. The Ref Manual has the following description of this bit:DMA Disable ...
Hi!I was wondering if anyone has any insight into the temperature rating testing for the STM32 MCUs.Particularly, how can ST establish if a MCU is rated for 85*C or 105*C and how are those differentiated in the manufacturing process?Are MCUs which ar...
