Global variable to give and record information of the setup request management.
This global variable allows to decode and response a setup request. It can be updated by udc_process_setup() from UDC or *setup() from UDIs.

Data Fields | |
void(* | callback )(void) |
Callback called after reception of ZLP from setup request. More... | |
bool(* | over_under_run )(void) |
Callback called when the buffer given (.payload) is full or empty. More... | |
uint8_t * | payload |
Point to buffer to send or fill with data following SETUP packet This buffer must be word align for DATA IN phase (use prefix COMPILER_WORD_ALIGNED for buffer) More... | |
uint16_t | payload_size |
Size of buffer to send or fill, and content the number of byte transfered. More... | |
usb_setup_req_t | req |
Data received in USB SETUP packet Note: The swap of "req.wValues" from uin16_t to le16_t is done by UDD. More... | |
