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) |
Opens the communication port This is called by CDC interface when USB Host enable it. More... | |
void | main_cdc_set_dtr (uint8_t port, bool b_enable) |

bool | main_msc_enable (void) |
Called by MSC interface Callback running when USB Host enable MSC interface. More... | |
void | main_resume_action (void) |
Called by UDD when the USB line exit of suspend state. More... | |
void | main_sof_action (void) |
Called when a start of frame is received on USB line. 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... | |

void main_cdc_disable | ( | uint8_t | port | ) |
Closes the communication port This is called by CDC interface when USB Host disable it.
bool main_cdc_enable | ( | uint8_t | port | ) |
Opens the communication port This is called by CDC interface when USB Host enable it.
Called by CDC interface Callback running when USB Host enable CDC interface.
true | if cdc startup is successfully done |
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.
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
void main_msc_disable | ( | void | ) |
Called by MSC interface Callback running when USB Host disable MSC interface.
bool main_msc_enable | ( | void | ) |
Called by MSC interface Callback running when USB Host enable MSC interface.
true | if MSC startup is ok |
void main_resume_action | ( | void | ) |
Called by UDD when the USB line exit of suspend state.
Turn on a led to notify active mode Called when the USB line is resumed from the suspend state.

void main_sof_action | ( | void | ) |
Called when a start of frame is received on USB line.
Manages the leds behaviors Called when a start of frame is received on USB line each 1ms.
