Hello STM Community, I want to implement on STM32H723 ultrasonic sensor and I use TIM8 Input Capture mode to read time between falling edges. It worked on interrupts, but I want to use DMA in order prevent interrupt storm and to speed up calcula...

Hello.I'm currently researching can communication with stm32f407vgcurrently, i want to use can1 and can2 at the same time, but only one of them works.canfilter is used, and the test is currently in progress through timer interupt.maybe the can fi...
I have setted:SYSCLK: 250 MHzHCLK: 250 MHzAs a SysTick source I tried: HCLK, HCLK/8, LSISTM32Cube FW_H5 V1.4.0I'm getting 2ms instead of 1ms in any configuration. Any idea how to fix it?
Hi, i need help with a strange behaviour of the FDCAN RX interrupt. I have 2 controllers which communicate with each other over CAN bus (Classic CAN). The first (my problem mcu) sends a command message and the second answers with 3 messages. The prob...
Hi For a basic test to verify the hardware of my PCB is OK, i want to make a loopback between PA0 and PA1, I see on the stm32u585ci doc that PA0 can not be configure as simple GPIO (PA1 is possible)It is correct? Thank you.
Hello, I am a beginner in Embedded systems and I have the board DevEbox STM32H7XX with STM32H743VIT6. when i come to select it in Stm32cubeide I don't find this board. how can i fix it? Thank you in advance
Hi @mƎALLEm ,I referred the application notes to increase analog amplitude, but whatever the digital amplitude configured i am able to get only 1.85v as analog volt. How to get 3.3v as volt level for output for DAC.
Can the memory generated by DMA be accessed and used as data? And how?
Setup- I am using Platform I/o to upload code to STM32 , Teensy. I am Sending Data from one STM to another STM via CAN and the message that I received on STM I am communicating it through UART to Teensy to Serial print it. I couldn't Serial print us...
