I have implemented a fully working usart keyboard with interrupts in a Nucleo L412Kb. The main code loop checks whether a pending-key flag and no-bouncing flag are set, then scans the rows in the selected keyboard matrix column, and sends the key via...
I want to implement communications between two MCUs over USB.I have a Freertos application running on a Nucleog474RE board to which I've added the USB CDC device.I'm using CubeMX 6.11 and CubeIDE 1.15.0.I have attached a USB cable to PA12 & PA11 and...
My goal is to install linux on the stm32f769-dk board.I have no such experience before.I compiled the build kernel with buildroot and installed it on the board. Linux worked but the only problem is that buildroot should normally load the image to the...
I have a stm32h750-dk board that I played with long time ago, so I forgot what I did, but since connector CN5 has pins soldered on I guess I tried to program the board through that connector.Well - the board is not detected when connected to the PC a...
So we have a custom board from which we want to read a pressure sensor slave information via SPI.And a similar exercise we have done with the NUCLEO board as well. NUCLEO756Z.On the Nucleo the code run for a short while and then after half an hour it...
I am trying to create a basic setup for STM32L4R9-DISCO with CubeMX and TouchGFX.TouchGFX complains about more than one layer being active from the LTCD module.But I cannot figure out how to disable a layer in the LTDC.
@Peter BENSCH Hi Peter,Please clarify the foot-print land-pattern in STM32G431MB as shown below. The actual pitch is 0.5 mm and for pins 1 to pin 20, the pitch should be 19*0.5 = 9.5 mm. But it is showing 9.8 mm in the datasheet. Regards,Sreejith
Hello, I am very new to micro electronics. I have been trying to set up reading CAN bus messages using my Nucleo board with a can tranceiver SN65HVD230.I have found many examples , but not for the F334R8T6Nucleo. I attempted to export numerous exampl...
Hi, guys:I want to excute code from sdram with stm32h747i-DISCO board,but it run into MemManager Fault.I read the AN5188，but find no example for stm32h747i-DISCO board. So I build 2 projects to test with this board.First project is the "bootloader" ,...
Hello ! Ijust found my h563zit6 has an 8-bytes rxfifo in i3c. I attach it to another i3c controller , and it olny received 8 bytes data. How can i receive data larger than 8 bytes? Thanks!
