Hello I have a project that uses the STM32F429 chip.Used the ltdc peripheral and spi-dma peripheral,The data of ltdc and spi both come from sdram.For ltdc peripheral,Because I want to use double buffering,I must know when the frame has completed refr...
Hello,I am experimenting on the STM32H45 Discovery Board (Dual Core) to use some GPIOs from different Core-Context.I initialized few Pins only for the CM7 and few dedicated pins only for the CM4. When I perform a debug session, all the mentioned pin...
Hello everyone, I’m currently experiencing difficulties with setting up CAN communication on my STM32F4 microcontroller. Despite having configured the CAN interface and connecting it to a CAN transceiver, I observe no activity on my designated can_tx...
Moved from this thread. HiI'm experiencing the same issue that others have reported with the STM32H755ZIT6. Despite following all the suggested solutions step by step from various forum threads, I’m still unable to debug or run code on my Nucleo boar...
Hi everybody,I'm trying to set up a communication with a can bus.I'm using a STM32F446. I use PB12 & PB13 (CAN2). I can see RX frames on PB12.I'd like to read frames that I received by using interrupts.I've found this example : https://github.com/STM...
Hi,couldn't find any STM32 dev kit that has DSI display interface and a demo where it plays video (or at least graphics) directly from SD card using DMA.Which ST dev kit does that? Thank you
Specifically, I require a timer for creating a clock to a peripheral. I chose PH5 (Timer12 Channel 2) because of the allocation capability in CubeMX, however, the datasheet for the STM32H757 does not show that as an alternate function.I have confirm...
Hello,I'm planning to use the STM32F413VGT3 in my project. It says it has three CAN buses. Can I use these three lines independently? Some of my research (ChatGPT) indicates that the third CAN line is not a standard CAN bus. I'd appreciate any clarif...
Hi everyone, I'm stuck on the transition from my low-power mode versus my power consumption.I already have a “sleep.c” code that is capable of putting the device to sleep at 2uA power consumption (which is my goal, everything's fine here).This code e...
Hello, I'm using STM32L471 and Micron MT25QL NOR Flash with single SPI interface. MT25 is also connected with other MCU (NRF52) using the same lines. I'm trying to write STM firmware in BOOT0 serial bootloader controlled by NRF using STM's USART3. Th...
