5416/320AD77 Interfacing??? - Geoffrey Wang - Nov 29 15:08:00 2001

Hi, I've been having a terrible time just trying to program a McBSP to produce any output on any line (I'm attempting to interface a 5416 with a TL320AD77 via a McBSP in SPI Master mode). It must be something very obvious... #define ADC_BSP hMcbsp1 MCBSP_start (ADC_BSP, MCBSP_XMIT_START | MCBSP_RCV_START, 0); while (TRUE) { while (!MCBSP_xrdy (ADC_BSP)); MCBSP_write16 (ADC_BSP, 0x5555); } with the typical DSP/BIOS initialization: MCBSP_Handle hMcbsp1; void CSL_cfgInit() { CSL_init(); hMcbsp1 = MCBSP_open(MCBSP_PORT1, MCBSP_OPEN_RESET); MCBSP_config(hMcbsp1, &mcbspCfg1); } MCBSP_Config mcbspCfg1 = { 0x1000, /* Serial Port Control Register 1 */ 0x0200, /* Serial Port Control Register 2 */ 0x0040, /* Receive Control Register 1 */ 0x0005, /* Receive Control Register 2 */ 0x0040, /* Transmit Control Register 1 */ 0x0005, /* Transmit Control Register 2 */ 0x00ff, /* Sample Rate Generator Register 1 */ 0x2000, /* Sample Rate Generator Register 2 */ 0x0000, /* Multichannel Control Register 1 */ 0x0000, /* Multichannel Control Register 2 */ 0x0f0e, /* Pin Control Register */ ...rest 0s... } Any help or suggestions would be greatly appreciated.
