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...
I am working with an STM32U575, HAL version 1.5 and found the issue described below(Have checked the HAL code for the H5 and H7 and these contain the same issue)See picture below, when aborting an PSSI transfer, before checking the state on lines 125...
