From e071f3897a0946c6be1e1b5e1f78eda8dcbf6fc7 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Tue, 21 Jul 2009 13:31:21 +0000 Subject: Added new USB_DeviceState variable to keep track of the current Device mode USB state. Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers. Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality. Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead. Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true. --- Demos/Device/ClassDriver/USBtoSerial/USBtoSerial.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Demos/Device/ClassDriver/USBtoSerial') diff --git a/Demos/Device/ClassDriver/USBtoSerial/USBtoSerial.c b/Demos/Device/ClassDriver/USBtoSerial/USBtoSerial.c index ac63f0f9f..89537066c 100644 --- a/Demos/Device/ClassDriver/USBtoSerial/USBtoSerial.c +++ b/Demos/Device/ClassDriver/USBtoSerial/USBtoSerial.c @@ -152,7 +152,7 @@ void EVENT_USB_UnhandledControlPacket(void) */ ISR(USART1_RX_vect, ISR_BLOCK) { - if (USB_IsConnected) + if (USB_DeviceState == DEVICE_STATE_Configured) Buffer_StoreElement(&Tx_Buffer, UDR1); } -- cgit v1.2.3
