Why the Hyperbus frame sent from NUCLEO-L4R5ZI-P board has not the good shape?
My purpose is to send an "HELLO" using a NUCLEO-L4R5ZI-P board trough HYPERBUS.On the STM32CubeIDE, I configurated OCTOSPI1 peripherial and I/O associated./* USER CODE END Header */ /* Includes -------------------------------------------------------...
stm32f030 programming using stm32 flash loader
hi every one.I want to program an stm32f030 chip using stm32 flash loader. I know this programmer communicates with the boot program of the MCU. I used this programmer for a microcontroller of mine in a custom designed board (which has been programed...
Resolved! weird CANBUS signal shape, different voltages within the same frame?
Question for the Hardware-wise ones:When probing canH and canL with my isulated oscilloscope i get the following signal:different voltage levels inside the same frame??!.Notice how the ACKs are always higher voltage alsoIt doesnt happen always but ev...

STM32F0 CubeMx SPI HAL Driver Initial Pin Level
Hi there, I created a project with STM32F042G6 chip using CubeMX. I am interfacing this IC to another chip using SPI. When I set the SPI1 and try to send a command, just before sending a command I have SCLK, MOSI, and MISO levels are high. After send...

STM32H743ZI2 CAN message receive issue with MCP2551
I have hooked up a STM32H743ZI2 Nucleo board with a CAN tranceiver MCP2551 following the instructions kindly provided by mr. Hudak (https://os.mbed.com/users/hudakz/code/CAN_Hello/) with the exception of replacing the second board with a USB-CAN-modu...
Issue with the STM32H735-DK, OSPI Hyperram
Hi, in the example for the OSPI-memorymapped example, the test procedure is as follows..// This is running fine on the DEV board, ( it also works in byte mode fine.) while (1) { /* Intensive Access ---------------------------------------------...
STM32H735 OCTOSPI2 Hyperram Errors
Using the STM32H735G-DK with on board external memory connected to OCTOSPI2.I'm using the demo code for this board to initialise the OSPI2 interface and to access the on board HyperRAM (S70KL1281DABHI023). The demo code writes 32-bits and reads them...
