C++ (Cpp) acc_write_register Examples

Example #1

File: spi_accel.c Project: janeelke/ME433_Homework

void acc_setup() {
  TRISAbits.TRISA4 = 0; // set CS to output and digital if necessary
  CS = 1;

  // select a pin for SDI1
  SDI1Rbits.SDI1R = 0b0001;//set RPB5 to be SDI1

  // select a pin for SD01
  RPB2Rbits.RPB2R = 0b0011; //set RPB2 to be SD01

  // Setup the master Master - SPI1
  // we manually control SS as a digital output 
  // since the pic is just starting, we know that spi is off. We rely on defaults here
 
  // setup spi1
  SPI1CON = 0;              // turn off the spi module and reset it
  SPI1BUF;                  // clear the rx buffer by reading from it
  SPI1BRG = 0x3;            // baud rate to 5MHz [SPI1BRG = (40000000/(2*desired))-1]
  SPI1STATbits.SPIROV = 0;  // clear the overflow bit
  SPI1CONbits.CKE = 1;      // data changes when clock goes from active to inactive
                            //    (high to low since CKP is 0)
  SPI1CONbits.MSTEN = 1;    // master operation
  SPI1CONbits.ON = 1;       // turn on spi
 
  // set the accelerometer data rate to 1600 Hz. Do not update until we read values
  acc_write_register(CTRL1, 0xAF); 

  // 50 Hz magnetometer, high resolution, temperature sensor on
  acc_write_register(CTRL5, 0xF0); 

  // enable continuous reading of the magnetometer
  acc_write_register(CTRL7, 0x0); 
  acc_write_register(0x21,0);

  CS = 1;

  // select a pin for SDI1
  SDI1Rbits.SDI1R = 0b0001;//Pin RB4 = Pin 11

  // select a pin for SD01
