From 215f8603b14cc29e08d8a25e08f8eca44ed90826 Mon Sep 17 00:00:00 2001 From: hathach Date: Fri, 16 Nov 2018 21:56:39 +0700 Subject: nrf5x: refactor device control transfer. - make control transfer as part of usbd. Class driver must use usbd_control_ API() instead of dcd_ api. - change the signature of class driver's control_request - allow control request complete to stall in staus stage - move control request parser & handling to usbd. --- src/device/dcd.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'src/device/dcd.h') diff --git a/src/device/dcd.h b/src/device/dcd.h index ff836f405..bd0ea852e 100644 --- a/src/device/dcd.h +++ b/src/device/dcd.h @@ -124,6 +124,10 @@ void dcd_event_xfer_complete (uint8_t rhport, uint8_t ep_addr, uint32_t xferred_ /*------------------------------------------------------------------*/ /* Endpoint API + * Note: + * - Address of control endpoint OUT is 0x00, In is 0x80 + * - When stalling control endpoint both control OUT and IN must be stalled + * (according to USB spec, stalled control is only recovered with setup token) *------------------------------------------------------------------*/ bool dcd_edpt_open (uint8_t rhport, tusb_desc_endpoint_t const * p_endpoint_desc); bool dcd_edpt_xfer (uint8_t rhport, uint8_t ep_addr, uint8_t * buffer, uint16_t total_bytes); -- cgit v1.3.1
