Hello Clark,
Unfortunetly we do not have sample code for the device. The most common issue when communicating with devices is timing errors. I would suggest to look closely to the timing diagram in the datasheet.
If you have any inquiries concerning the MSP430, I suggest posting again in their desginated forum area.
Regards,
Cynthia
How can i know that command is sent correctly?
if i want to send a RST command
my command like that: (Cmd = 0x85)
void ADS8698_CMD(uchar Cmd)
{
//Cmd = 0x85;
AVCS = 0; //CS LOW
delay_us(2);
for(i=0;i<8;i++) //Send CMD MSB 8bit
{
AVSCLK = 1 ; // SCLK HI
if(Cmd & 0x80)
AVSDI = 1;
else
AVSDI = 0;
delay_us(2);
AVSCLK = 0; //SCLK LOW
delay_us(2);
Cmd =Cmd << 1;
}
AVSDI= 0 ; //Send CMD LSB 8bit
delay_us(2);
for(i=0;i<8;i++)
{
AVSCLK = 1;
delay_us(2);
AVSCLK = 0;
delay_us(2);
}
r=0;
for (i=0;i<18;i++) //Read previous data
{
r = r<< 1;
AVSCLK = 1; // SCLK HI
if(AVSDO) //Check SDO 1 or 0
r = r | 0x0001;
else
r = r & 0x03fe;
delay_us(2);
AVSCLK = 0; // SCLK LOW
delay_us(2);
}
AVCS = 1; //CS HI
delay_us(2);
}
