Hi, we are working with SC28C94 for data communication. this IC(SC28C94) we are using in polling mode not in interrupt mode.My main aim is to trasmit a single charecter(ie A(0x41) or B(0x42) or .....) continuously. we are giving 8MHz clock from external. Here iam sedning my Code
typedef unsigned long USHORT; typedef unsigned int UINT; typedef unsigned char UCHAR;
int main() { UINT *Tx; UINT *Rd_st; UINT *Base,*Cmd,*Aux,*Comm;
Base = (UINT *)0x10000000; /* MR0, MR1,MR2 Addr */ Comm = (UINT *)0x10000004; /* CSR Addr */ Cmd = (UINT *)0x10000008; /* CR Addr */ Aux = (UINT *)0x10000010; /* ACR Addr */
Rd_st = (UINT *)0x10000004; /* SR Addr */ Tx = (UINT *)0x1000000C; /* Tx HOLD Addr */
*Base = 0x07; /* Even parity ,8 bits/char */ *Base = 0x07; /* 1 stop bit */ *Comm = 0x0B; /*9600 bps */ *Cmd = 0x06; /* Tx Enable and Rx Disable */ *Aux = 0x00; while(1) { while(((*Rd_st)&0x04)==0x00); /* check TxRdy bit =1 in SR */ *Tx = 0x43; } }by using the above code , we are recieving the data but junk. if any one knows about This Quart,please veryfy our code and if possible suggest any modifications required to getthe exact data.
Thanking You waiting for your response ASAP.
