Functions | |
int | main (void) |
Main function. Execution starts here. More... | |
void | main_cdc_disable (uint8_t port) |
Closes the communication port This is called by CDC interface when USB Host disable it. More... | |
bool | main_cdc_enable (uint8_t port) |
Called by CDC interface Callback running when USB Host enable CDC interface. More... | |
void | main_cdc_set_dtr (uint8_t port, bool b_enable) |
Save new DTR state to change led behavior. The DTR notify that the terminal have open or close the communication port. More... | |
bool | main_extra_string (void) |
Example of extra USB string management This feature is available for single or composite device which want implement additional USB string than Manufacture, Product and serial number ID. More... | |

Called by MSC interface Callback running when USB Host disable MSC interface. More... | |
bool | main_msc_enable (void) |
Called by MSC interface Callback running when USB Host enable MSC interface. More... | |
void | main_resume_action (void) |
Turn on a led to notify active mode Called when the USB line is resumed from the suspend state. More... | |
void | main_sof_action (void) |
Manages the leds behaviors Called when a start of frame is received on USB line each 1ms. More... | |
void | main_suspend_action (void) |
Enters the application in low power mode Callback called when USB host sets USB line in suspend state. More... | |

bool main_extra_string | ( | void | ) |
Example of extra USB string management This feature is available for single or composite device which want implement additional USB string than Manufacture, Product and serial number ID.
Called by UDC when USB Host request a extra string different of this specified in USB device descriptor.
return true, if the string ID requested is know and managed by this functions
