Hi,I want to put the USB bus into SUSPEND/RESUME state, currently I'm using gState in USBH_HandleTypeDef to manually put the device into HOST_SUSPENDED state and similarly to move to the Idle state I'm manually assigning gState to be HOST_IDLE.With t...
Hello,Currently I'm playing around with the I3C peripheral and I try to implement a sort of "eeprom" interface on a I3C target where I have 10 slots which I want to be able to address separately.So on the controller side I have this function: int i3...
To Andrew, SofLi Hy Andrew and SofLi. I well received your last informations posted this week-end. Therefore it was week-end. I test a NUCLEO board without ST-link; my computer is a Mac-mini and the NUCLEO board offers capabilities to be separate in ...
"Hello, I'm currently working with the FDCAN module on the STM32H747I-DISCO board. I've successfully configured both FDCAN modules in the M7 core, and they are working as expected. However, when attempting to configure them in the M4 core independent...
I'm trying to program STM32WBR55VGY microcontroller in my custom board.Recently, I succeed to debug my microcontroller but after one time, I can see this message on the STM32cubeIDE during debugging and the microcontroller does not work properly."Bre...
I received a recommendation for the U5 series for its low power consumption for medical patient monitors. As a beginner, my experience is limited to the F446RE and H743 Nucleo boards. I chose the STM32F769-DISC0 for its ease of use and integrated dis...
CUBEMX, STM32G473 MCU is used.LIN communication worked well when using STM32F103, but after replacing only the MCU on the PCB board, LIN communication does not work.When the MCU was replaced, the HAL_Delay() function did not work,'#define USER_VECT_T...
Hi,I am working with STM32G4.I am communicating with STM32G4 with other controller through UART interrupt communication. The data is transmitting and receiving between stm32g4 and other mcu. Some times I am not receiving the data properly from other...
I am writing to an SD card using the Adafruit_Shield BSP library on the STM32L4R5ZI Nucleo board. I had it writing 10 values, from 0x00 to 0x09 but the second byte (with a value of 0x01) was getting corrupted as set to 0x00. I changed the array so ...
Hi all, Working on STM32H745: when enabling the M4 at M7 main(), the 'D2 domain' SRAMs (1,2,3) are being reset, causing issue, as the M7 and the OS are using these SRAMs, prior of the M4 enable (RCC register). Is there any option not to reset the ...
