From a9d5e129b76449c73a853af450d7d353512cd3a0 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Wed, 5 Aug 2009 09:37:45 +0000 Subject: Changed over manual loops waiting for endpoints to be ready to use the library Endpoint_WaitUntilReady() function for robustness. Fixes issues with terminated transfers on the host locking up USB devices. --- Demos/Device/LowLevel/USBtoSerial/USBtoSerial.c | 12 ++---------- 1 file changed, 2 insertions(+), 10 deletions(-) (limited to 'Demos/Device/LowLevel/USBtoSerial/USBtoSerial.c') diff --git a/Demos/Device/LowLevel/USBtoSerial/USBtoSerial.c b/Demos/Device/LowLevel/USBtoSerial/USBtoSerial.c index bb1b4da2d..736c0af10 100644 --- a/Demos/Device/LowLevel/USBtoSerial/USBtoSerial.c +++ b/Demos/Device/LowLevel/USBtoSerial/USBtoSerial.c @@ -263,11 +263,7 @@ void CDC_Task(void) if ((Tx_Buffer.Elements) && LineEncoding.BaudRateBPS) { /* Wait until Serial Tx Endpoint Ready for Read/Write */ - while (!(Endpoint_IsReadWriteAllowed())) - { - if (USB_DeviceState == DEVICE_STATE_Unattached) - return; - } + Endpoint_WaitUntilReady(); /* Write the bytes from the buffer to the endpoint while space is available */ while (Tx_Buffer.Elements && Endpoint_IsReadWriteAllowed()) @@ -287,11 +283,7 @@ void CDC_Task(void) if (IsFull && !(Tx_Buffer.Elements)) { /* Wait until Serial Tx Endpoint Ready for Read/Write */ - while (!(Endpoint_IsReadWriteAllowed())) - { - if (USB_DeviceState == DEVICE_STATE_Unattached) - return; - } + Endpoint_WaitUntilReady(); /* Send an empty packet to terminate the transfer */ Endpoint_ClearIN(); -- cgit v1.2.3
