Hi, I am a student. I got some interfacing problems. I have been generated some sample code form CCS V2,0 by using tool ->data converter support option. They are , dc_conf.h , t1206_fn.h, tidc_api.h, t1206_ob.c and tidc_api.c. as attached files. I have some questions for the sample code in dc_conf.h file as follows: /************** dc_conf.h ****************/ /* ADC 1 parameter data */ #define ADC1_TYPE THS1206 #define ADC1_CR0_VALUE (0x0) #define ADC1_CR1_VALUE (0x84) #define ADC1_TRIGGER_LEVEL (4) #define ADC1_NR_CHANNEL (1) #define ADC1_SAMPLE_FREQ (1000) #define ADC1_SHIFT (20) #define ADC1_INTNUM (6) #define ADC1_BUS_NONE /* EMIF Interface parameters */ #define ADC1_ADDRESS (0xA0000000) #define ADC1_RDSETUP (1) /* read */ #define ADC1_RDSTRB (4) #define ADC1_RDHLD (1) #define ADC1_WRSETUP (4) /* write */ #define ADC1_WRHLD (6) #define ADC1_WRSTRB (3) #define ADC1_TIM_PERIOD (0x0012) /*****************************************************/ Q1: What is the exactly ADC1_ADDRESS value? Q2: Is ADC1_SHIFT needed? Do I need to do data shift when I doing read/write actions for little endian? Q3: What kind of situations I may use ADC1_RDSETUP, ADC1_RDSTRB, ADC1_RDHLD defined in dc_conf.h? Could you give me some hints or suggestions? Maybe you have sample code ?
