CAN是一种使用硬件控制器的通信协议,而I2C和SPI是使用软件控制的通信协议。PSOC5的硬件架构不支持将CAN与I2C或SPI外设一起使用。
要在PSOC5上运行ADXL345,您需要使用I2C或SPI外设来与传感器进行通信。以下是一些适用于PSOC5的I2C和SPI外设的示例代码:
1. I2C外设示例代码:
```
#include "project.h"
#define ADXL345_ADDR 0x53
int main(void)
{
CyGlobalIntEnable; /* Enable global interrupts. */
I2C_Start();
// Configure ADXL345
uint8 configData[2] = {0x31, 0x0B};
I2C_I2CMasterWriteBuf(ADXL345_ADDR, configData, 2, I2C_I2C_MODE_COMPLETE_XFER);
while (0u == (I2C_I2CMasterStatus() & I2C_I2C_MSTAT_WR_CMPLT))
{
/* Wait until master completes write transfer */
}
for(;;)
{
// Read data from ADXL345
uint8 readData[6];
I2C_I2CMasterReadBuf(ADXL345_ADDR, readData, 6, I2C_I2C_MODE_COMPLETE_XFER);
while (0u == (I2C_I2CMasterStatus() & I2C_I2C_MSTAT_RD_CMPLT))
{
/* Wait until master completes read transfer */
}
// Process data
CyDelay(100);
}
}
```
2. SPI外设示例代码:
```
#include "project.h"
#define ADXL345_SELECT() SPI_ss_Write(0)
#define ADXL345_DESELECT() SPI_ss_Write(1)
int main(void)
{
CyGlobalIntEnable; /* Enable global interrupts. */
SPI_Start();
for(;;)
{
ADXL345_SELECT();
// Send read command to ADXL345
uint8 cmd = 0x32 | 0x80; // Read multiple bytes with auto-increment
SPI_WriteTxData(cmd);
SPI_ReadRxData(); // Clear RX buffer
// Read data from ADXL345
uint8 readData[6];
for (int i = 0; i < 6; i++)
{
SPI_WriteTxData(0); // Dummy write to generate clock signal
readData[i] = SPI_ReadRxData();
}
ADXL345_DESELECT();
// Process data
CyDelay(100);
}
}
```
这些示例代码演示了如何使用I2C和SPI外设来与ADXL345传感器进行通信。您可以根据这些示例代码进行修改,以满足您的特定需求。
