detecting STM32 via coolterm / teraterm to send a char

Hi , i wanted to connect and send a char from my stm32 blue pill but i cant connect it to the serial monitor via tera twerm or cool term ( the stm32 is connected to usb via an st link v2 and it is detected) making an led blink is possible but i cant...

SPI max frequency test

Hey,I would like to use an ADC LTC2315,in maximum SPI interface (87.5Mhz Fclk).Does anyone tried to work with the STM32H743 In SPI At this Frequency, or more?From DS, in master mode Channel 1 can work in Max of 133MHz, hope it really does.Moreover, c...

Littlefs and flash lifespan calculation ?

Hi,In my office, I use a custom STM32F767GTx card with a QSPI N25Q128A flash memory.I use littlefs to create, write and read files.My software works well, I monitor some inputs and store these values in a file.Every 24 hours, I have a 200 kbytes file...

Where is the NUCLEO-L552ZE-Q default binary?

I'm talking about the firmware with which the Nucleo comes ex factory. It's not among the compiled binaries (https://www.st.com/en/evaluation-tools/stm32-discovery-kits.html#resource click on Binary resources - no direct link courtesy of the idiotic ...

STM32L412: When I turn the reset (physical) switch, the µC jumps into the DFU bootloader, although it isn't supposed to

Hi there!I have a weird problem, where I'm a bit lost, probably also due to my limited knowledge of assembly. So I am trying to write a function (which is called using a very secret pattern) which sets a magic number and soft resets the microcontroll...

Hi , I use ST micro controller: STM32H743VIT6 1. I want to knew if the I/O pins are 5-Volt tolerant? 2. in the Datasheet i reed there is a I/O structure called FT. This structure can tolerate 5V. How VDD_FT in this structure get 5V?

Why does the I2C state remain in HAL_I2C_STATE_BUSY_TX when an access is completed.

I am doing a DMA based I2C transmit using HAL_I2C_Master_Transmit_DMA and am seeing an issue with the state of the I2C. The transfer completes as expected as confirmed using an oscilloscope on the pins. However, the state of the I2C gets switched to ...

SPI Communication with STM32G031 using HAL

Hello,I tried to configure the STM32G031K8 Nucleo Board using CubeMX to send a request to an attached sensor using SPI1. To my request (2 bytes) the sensor should answer with 4 bytes. I configured the data size to 8 bits and the clock parameters core...
