Hi, As I asked before, I'am trying to implement a simple FIR filter with 5409 EVM from Spectrum Digital. I found out that the example code i used was for the TLC320AC01 as A/D converter while 5409EVM uses TLC320AC50 as A/D converter. Is there any source code which works on this A/D converter? I've tried with SPC2 instead of SPC1 but it gave compile time error. Compiler(CC1.2) doesn't know about SPC2 while it knows SPC and SPC1. Many thanks. main_start: CALL init_54 ; initialize ST0,ST1 PMST ; and other registers CALL serial_init ; initialize serial port CALLD aic_init ; initialize AIC LD #0,DP NOP WAIT: B WAIT ; wait for receive interrupt aic_init: ANDM #~K_RINT1,IMR CALLD wrt_cnfg ; initialize AC01 STM #K_RINT1,IFR STM #K_RINT1,IMR RETD STM #K_RINT1,IFR .end wrt_cnfg: STM #K_0,DXR1 ;primary data word - a jump start!
