how to read the data from MISO pin, and how can I creat 96 clock ?
I have a question about the SPI read from slave. My ADC has six channel, so I need 96 clock. I wonder that is my code as follows correct?
-----
SPI spi(p5, p6, p7); mosi, miso, sclk
DigitalOut cs(p8);
int main() {
Select the device by setting chip select low
cs = 0;
Send 0x8f, the command to read the WHOAMI register
float CH_A0 = spi.write(0x00);
float CH_A1 = spi.write(0x00);
float CH_B0 = spi.write(0x00);
float CH_B1 = spi.write(0x00);
float CH_C0 = spi.write(0x00);
float CH_C1 = spi.write(0x00);
printf("CH_A0 = %f\n", CH_A0);
printf("CH_A1 = %f\n", CH_A1);
printf("CH_B0 = %f\n", CH_B0);
printf("CH_B1 = %f\n", CH_B1);
printf("CH_C0 = %f\n", CH_C0);
printf("CH_C1 = %f\n", CH_C1);
Deselect the device
cs = 1;
}
