Hi i am working with LTDC with STM32F429ZI Discovery -1 board with onboard LCD. I really want to drive a external LCD RGB display without An ic controller by utilising the Internal LTDC hardware inside the MCU . Can you please give some support on th...
Hi everyone.I'm trying to send more than 256 bytes of data from the host to the STM32 using USB CDC VCP, and I don't know why VCP won't accept more than 64 bytes of data. My project is already halfway done. If I switch to the USB bulk method, do I ha...
Hi, I have a question about supplying power to DSI interface on STM32H747BGT6 (208 LGFP package).RM0399 says, "The DSI interface is supplied from a dedicated VDD12DSI supply that can be provided eitherby the integrated DSI regulator or by an external...
Hi,I have a DMA2D issue with a STM32N6 Nucleo-144 board. I can use the DMA2D to blend two framebuffers if the inputs are in the AXISRAM1. However, when one of the framebuffers is in AXISRAM3 (NPU RAM), the DMA2D doesn't copy from the relevant framebu...
I just spent some time debugging a fundamental compatibility issue between an MPU and its RAM, and I wanted to share what I learned to save others the same headache. I was looking at using the STM32N657 (a powerful Cortex-A7 MPU) and almost made a cr...
Hello, I have designed a custom PCB using STM32N657I0HxQ and W25Q32JWZPIQ NOR flash. I am following the STM32N6 FSBL Load & Run tutorial https://community.st.com/t5/stm32-mcus/how-to-create-an-stm32n6-fsbl-load-and-run/ta-p/768206 , but have troub...
Hi, Im planning on using STM32H747BGT6 in LDO mode only and no USB interfaces will be used. What should I do with SMPS pins (VSSSMPS, VLXSMPS, VDDSMPS, VFBSMPS) and USB supply pins (VDD50_USB and VDD33_USB)? The datasheet nor the application note don...
Hi All,I'm new to using the STM32 and honestly had great grief trying to connect to the chip.I'm using STlink V3 and designed my own PCB.Trying to flash a F/W to the PCB. I ordered the PCB from JLCPCB.I keep getting unable to get core ID as a message...
The datasheet for STM32U585 and 575 list there are two SAI on the chip. In CubeMX I can only see SAI1 (A and B sub-blocks)Datasheet CubeMX pin menu
What does DMA Request synchronization do? In the case of SPI_Rx does it trigger SPI reception when TIM12 updates (overflow) if i set synchronization signal to be TIM12 TRGO
