Example for NUCLEO-F401RE for testing our Open Bench Logic Sniffer
Here there is the hex file to load on NUCLEO-F401RE and the Open Bench Logic Sniffer configuration file for test your tool.
If all work OK you must see the result below.
The delay is 2mS because 1mS is the Delay and another 1mS is the time used for toggle the pins.
Here there is the source code for NUCLEO-F401RE developed using the free STM32CubeIDE.
For import our project into your STM32CubeIDE see here.
