From 24e621a8d8424721ed21ce329d2a28dbf8c35343 Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Fri, 30 Jul 2010 03:52:11 +0000 Subject: Altered the CDC Deivice and Host Class drivers' receive byte routines, so that no data is indicated by a negative return value. Added auto flushing of OUT data to the CDC Host Class driver's USBTask function to automatically flush the send pipe buffer. --- Projects/Benito/Benito.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'Projects/Benito') diff --git a/Projects/Benito/Benito.c b/Projects/Benito/Benito.c index 23786fb9e0..ac1e064d58 100644 --- a/Projects/Benito/Benito.c +++ b/Projects/Benito/Benito.c @@ -92,9 +92,10 @@ int main(void) for (;;) { /* Echo bytes from the host to the target via the hardware USART */ - if (CDC_Device_BytesReceived(&VirtualSerial_CDC_Interface) && (UCSR1A & (1 << UDRE1))) + int16_t ReceivedByte = CDC_Device_ReceiveByte(&VirtualSerial_CDC_Interface); + if (!(ReceivedByte < 0) && (UCSR1A & (1 << UDRE1))) { - UDR1 = CDC_Device_ReceiveByte(&VirtualSerial_CDC_Interface); + UDR1 = ReceivedByte; LEDs_TurnOnLEDs(LEDMASK_TX); PulseMSRemaining.TxLEDPulse = TX_RX_LED_PULSE_MS; -- cgit v1.2.3
