One note, as this is global scope macro, using short names like this might clash with libraries. I would rather skip the macro name set in the config and use the full name that config would do MBED_CONF_TARGET_USP_SPEED would be by default? What is the reason for defining macro USB_SPEED and not using default generated name?

[bcostm]

OK no problem it will be better but I don't know how to do it ? I wanted to do the same as CLOCK_SOURCE configuration...

When I build the target, the automatically generated mbed_config.h file contains:

// Configuration parameters
#define MBED_CONF_PLATFORM_FORCE_NON_COPYABLE_ERROR 0                            // set by library:platform
#define MBED_CONF_PLATFORM_STDIO_BAUD_RATE          9600                         // set by library:platform
#define CLOCK_SOURCE                                USE_PLL_HSE_XTAL|USE_PLL_HSI // set by target:DISCO_F746NG
#define MBED_CONF_PLATFORM_STDIO_CONVERT_NEWLINES   0                            // set by library:platform
#define MBED_CONF_PLATFORM_DEFAULT_SERIAL_BAUD_RATE 9600                         // set by library:platform
#define MBED_CONF_PLATFORM_STDIO_FLUSH_AT_EXIT      1                            // set by library:platform
#define USB_SPEED                                   1                            // set by target:DISCO_F746NG

How do I generate the MBED_CONF_TARGET_USB_SPEED macro ?

[0xc0170]

If you remove macro_name from the config, that would do the trick.

[bcostm]

OK.

I have removed the line "macro_name": "USB_SPEED" in targets.json and the mbed_config.h file contains effectively the desired macro:

#define MBED_CONF_TARGET_USB_SPEED 1 // set by target:DISCO_F746NG

@bcostm Thanks, looks good now
