This command will simultaneously writes data to all CODE registers while updating all DAC registers. It means channel A and channel B
will simultaneously update to set value.
value: 0~4095 0~3.3V
 USB Interface
 Read
Source Code:
int fd ;
unsigned char buf[1024];
fd = open(“/dev/ ttyUSB0”, O_RDWR);
read (fd, buf,1024);
close(fd);
 Write
Source Code:
int fd ;
unsigned char buf[1024];
fd = open(“/dev/ttyUSB0”, O_RDWR);
write (fd, buf,1024);
close(fd);
