Hello,I implemented a FDCAN in bare metal on the STM32G491 that works on FDCAN1 (with one unrelated problem). Now I need the second one too. So when I try to send over FDCAN2 only garbage comes out on the CAN bus. Yet the CRC is correct so it is actu...
It's been almost two years since word first appeared about STM32N6, but there is still no public information about when it will actually show up.Can we expect some news about it at the STM32 Summit next week?If not, what can one do in order to get so...
I have a project to generate a sinusoidal signal using DAC and DMA. The waveform looks like a peak-flat-valley-flat pattern. I am using an array of 500 values, with the peak at 4095, flat at 2048, and the valley at 0. I utilize circular DMA to repeat...
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
