Generate a trace¶
This application note details how to generate a trace.
This is especially useful to debug or to create a ticket for the help-desk .
Configure¶
///
/// @brief SPI debugging for screen
/// @details 1 = activated, otherwise 0; recommended = 0
///
#define DEBUG_SPI_SCREEN 1
hV_Board.h header file of the hV_Board_EXT3 library, set DEBUG_SPI_SCREEN to 1.
The option is activated by default on the Evaluation edition.
Proceed with a clean build of the project.
Use¶
The trace is sent to the default serial UART port.
Open a terminal to display the serial port.
The trace is generated by the log system.

Below is an example of the output.
