Hi allI would like to create 2 virtual COM ports (VCPs) using the CDC class in USBX. The .ioc only allows for one unique PID and VID, but it appears that multiple interfaces can be created of the same class.I want to know if it is possible to create ...
Hello,I want to use the USBX MTP stack on a stm32u5 without threadx. The configuration in stm32CubeMx worked fine but when i run the programm, i get UX_FUNCTION_NOT_SUPPORTED from this location: UINT _ux_device_class_pima_initialize(UX_SLAVE_CLASS_C...
First post, please let me know if I've made any mistakes in asking my question.I'm trying to write a bootloader for a device using a STM32u585ZIT chip. When booting, it will read a partition table saved in flash to determine if it will boot from part...
Hi, I'm working on a project which requires USB MIDI functionality. I looked into a couple of videos where USB MIDI implementation was done on other boards, but when I try to do the same on mine it's not working. I'm using a NUCLEO board (H755ZIQ), I...
Hi, I'm using a nucleo board with stm32h755zi chip for prototyping a MIDI device. I am trying to get it working as both CDC and MIDI device via USB. I was able to achieve this using I-CUBE-USBD-Composite but there is a minor problem with the implemen...
Hello,Just wondering if anyone knows the reason for the duplicate writes to the following registers in the HAL Ethernet code please?ETH->MACCRETH->MACFCRETH->DMAOMRETH->DMABMRIn the example shown below (from HAL code) the DMA0MR register is written t...
Hello,I am utilizing the following components:Nucleo-H723ZH (STM32H723)eMMC: 4GBI have already created the following files:user_discio.cuser_discio.heMMC_Driver.ceMMC_Driver.hAfter connecting an SD card reader to the CN8 connector on the Nucleo STM3...
Hey all, I'm attempting to implement the EEPROM emulation library into a pre-existing project with little success. I've added the eeprom.c file to the project as well as the header include to the main.c but even prior to implementing the code, attemp...
I want to know which Wakeup pin or Reset pin wakes up the microprocessor that enters standby mode. I have 2 wakeup pins.I am monitoring SR1 and SR2 variables with Live expression in Debug mode, but when I wake up from standby mode, the value of the v...
Hello,We have a custom board based on the STM32U5A5ZJ, and are in the process of writing a zephyr driver for the two analog comparators on the MCU. Our use-case requires the driver to support interrupts on both comparators. Looking at the reference m...
