Hi,
I am using ADS8332 over MCBSP- SPI interface( I am using TMS320c6713 for DSP), and have the MCBSp peripheral for the following settings ->
mcr = 0x00000000; rcer = 0x00000000; xcer = 0x00000000; spcr = 0x02001800; /XINTM = XRDY; RINTM = RRDY; FREE RUNNING = YES; CLKSTOPDELAY = YES; NO SYNCERROR; DX - DISABLED, DLB - DISABLED rcr = 0x00040040; // SINGLE PHASE, FRAME IGNORE; 0BIT DELAY; FRAMELEN = 1, WORDLEN = 16; NO COMPAND - MSB; xcr = 0x00040040; // SINGLE PHASE, FRAME IGNORE; 0BIT DELAY; FRAMELEN = 1, WORDLEN = 16; NO COMPAND - MSB; srgr = 0x2019001E;// INTERNAL CLOCK SOURCE, DXRTOXSR; CLK DIV = 30; FRAME PERIOD 30; FRAME WIDTH = 1 pcr = 0x00000F05; // FSXM- FSRM = INTERNAL, CLKXM-CLKRM = OUTPUT; FSXP - FSRP = ACTIVE HIGH; CLKXP- CLKRP - FALLING EDGE;
and teh following pins
RESET - always high CONVST - always high EOC - i/p ( not monitered)...
I am sending following commands to the adc 8332 1) 0x0000 ( channel 0 select) 2) 0xe7fd ( CFR SETTINGS) 3) 0xC000 ( COMMAND TO READ CFR) 4) at this point i recieve 0xffff; ---> which is wrong
can any one tell me wher i have gone wrong, is there any problem with mcbsp settings or in sending the commands to the adc? is toggling convst and monitoring eoc essential for the proper working?
Regards,
Deepa
