hello sir, i m trying to interface ds1230 SRAM with 8051. bur i m not able to take out put.....pls help me..how to start with thi device to get out put...
sir i had spent almost 10 days for this....and still conti. but even still i m not able to get out output...here is my code... currently i m not using latch...i m directly connect the add. & data pin with 8051...
void ds1230_delay() { unsigned char i; for(i = 0; i <= 2; i++); }
void ds1230_write(unsigned char ltemp ,unsigned char htemp) {
CE = 1; WE = 1;
ladd = ltemp; hadd = htemp; ds1230_delay(); io_data = 0xFF;
CE = 0; WE = 0;
ds1230_delay(); ds1230_delay();
}
void ds1230_read(unsigned char Rltemp ,unsigned char Rhtemp) {
unsigned char data_out;
CE = 0; OE = 0;
ladd = Rltemp; hadd = Rhtemp; ds1230_delay(); data_out = io_data; transmit(data_out );
CE = 1; OE = 1;
void main() { init_serial(); //serial initialitation ds1230_write(0x00,0xF0); io_data = 0x00; while(1) {
ds1230_read(0x00,0xF0);
