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 I'm migrating my STM32F072 project to the STM32L072.In my original project (F072) I can jump to the DFU bootloader by software via a function located before SystemInit.I tried to convert this to be used by L072 by changing the address of bootlo...
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...
Hi , This is the first time I am using USB on STM32F401CCU6 blackpill.I am thinking of developing stereo microphone.To start with I am USING STM32CUBEIDE for development .Selected the STM32F401CCU6 in MCU and have configured the clock to 84Mhz.In Com...
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...
