Posted on November 15, 2007 at 06:39Hello,
I miss some guide from the documentation.
I want to use the FIFO. My Setup:
Code:
UART_Init(UART1);
UART_FifoConfig(UART1,ENABLE);
UART_Config(UART1,115200,UART_NO_PARITY,UART_1_StopBits,UARTM_8D);
UART_TimeOutPeriodConfig(UART1,0xFF);
UART_OnOffConfig(UART1,ENABLE);
Code:
UART_RxConfig(UART1 ,ENABLE);
UART_ItConfig(UART1,0xFF, DISABLE);
UART_ItConfig(UART1,UART_RxBufFull, ENABLE);
My ISR is:
Code:
if ( int_flags & UART_RxBufFull) { // Data received
UART_ItConfig(UART1,(UART_RxBufFull), DISABLE);
OSSignalBinSem(BINSEM_BT_RX); // Calls Task GetRX
}
Code:
void GetRX(void){
for(;;) {
OS_WaitBinSem(BINSEM_BT_RX,OSNO_TIMEOUT);
while( UART1->SR | UART_RxBufFull) {
g_rxbuf = UART1->RxBUFR & 0xFF;
...
}
UART_ItConfig(UART1,(UART_RxBufFull), ENABLE);
}
}
What I get, instead of
RINGis
RRRRRRRRRRRRIIIIIIIIIIIIINNNNNNNNNNNGGGGGGGGGGGGWhy that?
Sometimes 11,12,13 chars?
Will the FIFO-Pointer set through reading or have I to
Reset the FIFO. Only when?
When will the
RXBufNotEmpty reset, and why is it in the
STR71-Softlib named
RxBufFull?
Questions over questions.
Has one a document, where the UART is described in detail?
Or can you help me :o
Thanks,
Steffen
