以下是AD7606与ESP32的串行通信程序代码,仅供参考:
```c
#include <SPI.h>
// Define AD7606 pins
#define AD7606_CS_PIN 5 // Chip select pin
#define AD7606_RD_PIN 18 // Read pin
#define AD7606_RST_PIN 19 // Reset pin
// Define ESP32 pins
#define ESP32_SCK_PIN 18 // SCK pin
#define ESP32_MISO_PIN 19 // MISO pin
#define ESP32_MOSI_PIN 23 // MOSI pin
void setup() {
// Initialize AD7606 pins
pinMode(AD7606_CS_PIN, OUTPUT);
pinMode(AD7606_RD_PIN, OUTPUT);
pinMode(AD7606_RST_PIN, OUTPUT);
// Initialize ESP32 SPI pins
pinMode(ESP32_SCK_PIN, OUTPUT);
pinMode(ESP32_MISO_PIN, INPUT);
pinMode(ESP32_MOSI_PIN, OUTPUT);
// Initialize SPI communication
SPI.begin();
SPI.setClockDivider(SPI_CLOCK_DIV2); // Set SPI clock frequency to 20 MHz
SPI.setDataMode(SPI_MODE2); // Set SPI data mode to mode 2
SPI.setBitOrder(MSBFIRST); // Set SPI bit order to MSB first
// Reset AD7606
digitalWrite(AD7606_RST_PIN, LOW);
delayMicroseconds(1);
digitalWrite(AD7606_RST_PIN, HIGH);
delayMicroseconds(1);
}
void loop() {
// Select AD7606
digitalWrite(AD7606_CS_PIN, LOW);
// Read data from AD7606
uint16_t data = SPI.transfer16(0x0000);
// Deselect AD7606
digitalWrite(AD7606_CS_PIN, HIGH);
// Print data to serial monitor
Serial.println(data);
}
```
需要注意的是,此代码仅提供基本的SPI通信框架,具体的AD7606通信协议和数据处理需要根据具体情况进行实现。同时,由于AD7606与ESP32之间的通信是通过SPI总线进行的,因此需要在ESP32上配置正确的SPI引脚。
