STM32 MCUs Products

Where can I find the source code for the "en.stm324xg-eval_fw" I downloaded from the STM32F407 Eval section in st.com? It only contains the .hex and .dfu images. I would like the project in Cube or System Workbench.

The software is described in UM1492

Error Sending data to Arduino through UART Communication

Hi, I would like to send a data from my STM32F401CC to Arduino. I have connected Tx to Rx and successfully upload the code to stm32 and Arduino Uno. I don't get the values right, only first four readings, then all the values become random. This is my...

STM32F4 LINBUS Communication Example

Hello I am working with the STM32f4 development board. I'll make one LIN(Local Interconnet Network) master and one LIN Slave instance but I don't have any example.Has anyone created a sample code?
