Posted on November 18, 2005 at 06:05I'm trying to use UART1 as half-duplex. It looks ok, but I'm receiving back the last 3 chars everytime i try to send something.
any clue?
GPIO_Config(GPIO0, SMARTCARD_DATAIN_OUT, GPIO_AF_PP);
UART_OnOffConfig(UART1, ENABLE); // Turn UARTX on
UART_FifoConfig (UART1, DISABLE); // Disable FIFOs
UART_FifoReset(UART1, UART_RxFIFO); // Reset the UART_RxFIFO
UART_FifoReset(UART1, UART_TxFIFO); // Reset the UART_TxFIFO
UART_LoopBackConfig(UART1, DISABLE); // Disable Loop Back
// Configure the UARTX as following: - Baudrate = 9600 Bps Odd parity 8 data bits + 1 byte Parity 1.5 stop bit
UART_Config(UART1, 9600, UART_EVEN_PARITY, UART_1_5_StopBits, UARTM_8D_P);
UART_RxConfig(UART1, ENABLE); //Enable Rx
UART_ItConfig(UART1, UART_RxBufFull, ENABLE);
EIC_IRQChannelPriorityConfig(UART1_IRQChannel, 2);// Configure the EIC channel interrupt
EIC_IRQChannelConfig(UART1_IRQChannel, ENABLE);// Enable UART1 IRQ Interrupts
