My stm32l4 discovery kit iot node b-l475e-iot01 stopped the connection via connector 8, I couldn't do it at all, so I used ST-LINK V2, I got communication, but I can't use the USB again, I didn't touch the hardware, absolutely nothing.
I am using STM32F429 in my project which connects to an ATmega2560 thru UART. In arduino, there is a function Serial.Available() to check if the serial buffer is empty or not.Is there a function in STM32 that is similar to Serial.Available() in Ardui...
Deer electronicians,I was following the video "STM32 – Creating a File System on a SD card" from the ST Youtube channel.I done stricty the same things as in the video but an error occurs.../Core/Src/main.c:22:10: fatal error: fatfs.h: No such file or...
Hello,I tried to develop my first µC board inspired by the " adafruit feather STM32F405 express". For layout I used KiCad and the board is made by Chinese PCB manufacturer JLCPCB. To activate the DFU bootloader, the BOOT0 pin must be connected to 3.3...
Hello,so I am trying to set up a INA3221 current/voltage/power sensor with my STM32F469I-Disoc board. The I2C_adress ist 0x43 (or 0x86 if shifted left). I set up my I2C with CubeMX in 400kHz mode and already used to interact with a BME280 sensor. The...
Hello,I am trying to write data in .txt file on a USB pendrive at a certain frequency (in the while 1 loop) using STM32L496ZG as the USB host in the Mass Storage Class (MSC) configuration.I succeded writing to the .txt file in the first iteration, b...
Is there a way to use the HAL library to read the variable specified in the address?
Hello STM32-community,I'm struggling with the USB-connection via hTerm of my STM32. I'm trying to send a few bytes via USB, receiving them with the tool hTerm, but it cannot even connect to the Microcontroller. Terminal20141030 works just fine, whil...
Hi,it seems that the current STM32F4 HAL manual (UM1725, rev.6) is incomplete regarding the U(S)ART drivers, especially for the extension drivers: according to the source code (FW 1.26), there are UART extensions for receiving with idle line detectio...
