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...

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...
Hi I'm new to dual core programming. I need to share data from M7 core to M4 core and M4 core to M7 core. Can you please let me know the steps I need to start.?
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...
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 ---------------------------------------------...
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...
Hi, I would prefer to use my segger jlink debugger with the discovery board io using stlink. I see there is an unpopulated header with 3V3 , SWCLK, GND, SWDIO on the left side of the board, and there is an NRST pin on the back connectors so I think ...
Has anybody noticed this? Last activity time in old threads is updated and they raise up in "most recent activity" sorting order. For example this thread: what happened there on June 1 to update its activity time?
Dear community,In a project the microcontroller STM32G4 is used, where three ADCss with DMA are used. On each ADC three channels are configured with 2.5 cycle sampling. The ADCs are triggered with a timer with a frequency of 125kHz.The processed data...
