cs5530初始化程序 并与mega2560 spi通讯程序

以下是cs5530初始化程序的代码示例：

#include <SPI.h>

#define CS_PIN 10

void cs5530_init() {
  // Set SPI settings
  SPI.begin();
  SPI.setBitOrder(MSBFIRST);
  SPI.setClockDivider(SPI_CLOCK_DIV16);
  SPI.setDataMode(SPI_MODE0);

  // Set CS_PIN as output and pull it high
  pinMode(CS_PIN, OUTPUT);
  digitalWrite(CS_PIN, HIGH);

  // Send reset command to CS5530
  digitalWrite(CS_PIN, LOW);
  SPI.transfer(0x06);
  digitalWrite(CS_PIN, HIGH);

  // Wait for CS5530 to reset
  delay(100);

  // Send command to set up CS5530
  digitalWrite(CS_PIN, LOW);
  SPI.transfer(0x80);
  SPI.transfer(0x01);
  SPI.transfer(0x02);
  digitalWrite(CS_PIN, HIGH);

  // Wait for CS5530 to set up
  delay(100);
}

以下是与mega2560通过SPI通讯的代码示例：

#include <SPI.h>

#define CS_PIN 10

void setup() {
  SPI.begin();
  pinMode(CS_PIN, OUTPUT);
  digitalWrite(CS_PIN, HIGH);
}

void loop() {
  // Send command to select slave
  digitalWrite(CS_PIN, LOW);

  // Send data to slave
  SPI.transfer(0x01);
  SPI.transfer(0x02);
  SPI.transfer(0x03);

  // Deselect slave
  digitalWrite(CS_PIN, HIGH);

  // Wait for response from slave
  delay(10);

  // Read response from slave
  digitalWrite(CS_PIN, LOW);
  byte response = SPI.transfer(0x00);
  digitalWrite(CS_PIN, HIGH);

  // Do something with response
  // ...

  // Wait before sending another command
  delay(100);
}
