I am use the DSK 5402, and i have some problems with McBSP1, i cant drive
= out the CLKX1. my program: #include <stdio.h> extern void Config5402(); extern void ConfigMcBSP(); int data; ioport int port0004; void main(void) { Config5402(); /*Configura o DSP TMS320VC5402 */ port0004 = 0x0003; /*Configura a CPLD para usar o Barramento externo */ ConfigMcBSP(); /*Configura o McBSP1 para Master */ while(1){ *(volatile int*) 0x43 = 0xAAAA; /* McBSP1 data transmit register 1 *= / } } /*--- McBSP0 & McBSP1 Sub-Bank Addressed Registers ---*/ #define SPCR1 0x0000; /* Ser Port Ctrl Reg1 */ #define SPCR2 0x0001; /* Ser Port Ctrl Reg2 */ #define RCR1 0x0002; /* Rx Ctrl Reg1 */ #define RCR2 0x0003; /* Rx Ctrl Reg2 */ #define XCR1 0x0004; /* Tx Ctrl Reg1 */ #define XCR2 0x0005; /* Tx Ctrl Reg2 */ #define SRGR1 0x0006; /* Sample Rate Gen Reg1 */ #define SRGR2 0x0007; /* Sample Rate Gen Reg2 */ #define MCR1 0x0008; /* Multichan Reg1 */ #define MCR2 0x0009; /* Multichan Reg2 */ #define RCERA 0x000A; /* Rx Chan Enable Reg Partition A */ #define RCERB 0x000B; /* Rx Chan Enable Reg Partition B */ #define XCERA 0x000C; /* Tx Chan Enable Reg Partition A */ #define XCERB 0x000D; /* Tx Chan Enable Reg Partition B */ #define PCR 0x000E; /* Pin Ctrl Reg */ /* >>>>>> CONFIGURAO DO McBSP1 <<<<<<<<<< * Configurao para o McBSP1 funcionar como Master, n tendo necessidade de clock externo, para sincronismo entre DSP e AIC, os sinais de Frame Clock e Clock de sincronismo s gerados pelo DSP.*/ void ConfigMcBSP(void) { /*--- McBSP1 Registers ---*/ volatile int *McBSP1_SPSA = (volatile int *)0x0048; //Sub Bank Addr Reg volatile int *McBSP1_SPSD = (volatile int *)0x0049; //Sub Bank Addr Reg *McBSP1_SPSA = SPCR2; *McBSP1_SPSD = 0x0200; // MSB> 0000 0010 0000 0000 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = PCR; *McBSP1_SPSD = 0x2A0A; // MSB> 0010 1010 0000 1010 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = RCR2; *McBSP1_SPSD = 0x0045; // MSB> 0000 0000 0100 0101 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = XCR2; *McBSP1_SPSD = 0x0045; // MSB> 0000 0000 0100 0101 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = SRGR1; *McBSP1_SPSD = 0x0F0F; // MSB> 0000 1111 0000 0001 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = SRGR2; /* estes dados s importantes */ *McBSP1_SPSD = 0xE0FF; // MSB> 1111 0000 0000 0001 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = SPCR2; *McBSP1_SPSD = 0x0220; // MSB> 0000 0010 0000 0000 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); *McBSP1_SPSA = SPCR2; *McBSP1_SPSD = 0x02E1; // MSB> 0000 0010 1110 0001 <LSB asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); asm(" nop"); } |
