CONTEXT:I have been working with an STM32F429ZI Nucleo, trying to connect a USB thumb drive, to update the user application firmware. I have started with the MSC_Standalone project as it exists as an example for the F429ZI and I have been integrating...
I'm trying to implement a USB touchscreen on a NUCLEO F446ZE. I'm making a full-speed device using ST's USB library (Custom HID class) and I'm testing it with on a Windows 10 host. The first contact registers, but when I try to press another, it doe...
Hello,I have a SEPLOS brand battery management system card, and I want to read temperature and voltage data from this card. Initially, I will use an STM32F407VGT6 board to read data from the SEPLOS battery management system card via RS485. I am sendi...
Hello Community,I am encountering an error after my STM32H7ZIT6 device runs for a few hours. The device is intended to send and receive data from AWS. The error logs show repeated instances of mbedtls_ssl_read_record() returned -27648 (-0x6c00), ulti...
hello all, when I use HAL_FLASHEx_Erase() to erase sectors, it is ok! But when I use HAL_FLASHEx_Erase_IT() interrupt mode to erase sectors, it fails! It seems the interrupt not occuring! if I need to do more settings for flash in...
I am starting a personal project where I will be designing custom hardware and software for a device that would be be similar to a smartphone. I want it to be able to connect bluetooth, wifi, have speakers and use USB-C(power, data transfer, etc.). I...
Is there any way at all in PC software (Either the ST libraries or things like libUSB) to identify whether a device in DFU/Bootloader mode is an F407 or F411? Everything I can find in the USB properties is identical between the two (Same VID/PID, sam...
Hello everyone, I am using an STM32 microcontroller and I am facing a problem when I try to mount an external flash memory. The problem is inside the function lfs_dir_fetch which is returning unexpected values in the test buffer here: struct lfs_dis...
I'm trying to achieve a UDP communication with STM32H753IIT6 and LAN8720A.I use STM32CubeIDE 1.14.0.According to the ST Ethernet and LwIP example: Adam BERLINGER edited on 2023-12-07 , I create a project, and change the pin layout according to my...
We plan to use STM32G0 mcu with UCPD interface and external TCPP03-M20 protection circuit with single bi-directional power path in our smart power bank with replaceable smart battery and USB-C PD dual role power port application. There will be one US...
