在Keil软件中编写NXP SKEAZ128处理器UART2串口发送及接收8个字节为一帧的数组数据

在Keil软件中编写NXP SKEAZ128处理器UART2串口发送及接收8个字节为一帧的数组数据的代码如下：

#include <SKEAZ1284.h>

#define UART2_BAUDRATE 9600
#define FRAME_SIZE 8

void UART2_Init(void) {
    // Enable UART2 clock
    SIM_SCGC |= SIM_SCGC_UART2_MASK;
    
    // Configure UART2 pins
    PORTA_PCR14 = PORT_PCR_MUX(3); // UART2_TX
    PORTA_PCR15 = PORT_PCR_MUX(3); // UART2_RX
    
    // Disable UART2 while configuring
    UART2_C2 &= ~UART_C2_TE_MASK;
    UART2_C2 &= ~UART_C2_RE_MASK;
    
    // Configure UART2 baud rate
    uint16_t sbr = (uint16_t)((SystemCoreClock) / (16 * UART2_BAUDRATE));
    UART2_BDH = (UART2_BDH & ~UART_BDH_SBR_MASK) | UART_BDH_SBR(sbr >> 8);
    UART2_BDL = (UART2_BDL & ~UART_BDL_SBR_MASK) | UART_BDL_SBR(sbr);
    
    // Configure UART2 control register 1
    UART2_C1 = 0;
    
    // Enable UART2 transmitter and receiver
    UART2_C2 |= UART_C2_TE_MASK;
    UART2_C2 |= UART_C2_RE_MASK;
}

void UART2_SendFrame(uint8_t *data) {
    for (int i = 0; i < FRAME_SIZE; i++) {
        // Wait until transmit data register is empty
        while (!(UART2_S1 & UART_S1_TDRE_MASK));
        
        // Send data
        UART2_D = data[i];
    }
    
    // Wait until transmission is complete
    while (!(UART2_S1 & UART_S1_TC_MASK));
}

void UART2_ReceiveFrame(uint8_t *data) {
    for (int i = 0; i < FRAME_SIZE; i++) {
        // Wait until receive data register is full
        while (!(UART2_S1 & UART_S1_RDRF_MASK));
        
        // Receive data
        data[i] = UART2_D;
    }
}

int main(void) {
    // Initialize UART2
    UART2_Init();
    
    // Example array data
    uint8_t txData[FRAME_SIZE] = {0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08};
    uint8_t rxData[FRAME_SIZE];
    
    // Send array data
    UART2_SendFrame(txData);
    
    // Receive array data
    UART2_ReceiveFrame(rxData);
    
    // Check received data
    for (int i = 0; i < FRAME_SIZE; i++) {
        if (rxData[i] == txData[i]) {
            // Data received successfully
        } else {
            // Error in received data
        }
    }
    
    while (1) {
        // Add your code here
    }
}

以上代码实现了在Keil软件中编写NXP SKEAZ128处理器通过UART2串口发送和接收8个字节为一帧的数组数据。首先，在UART2_Init函数中，我们初始化了UART2模块和相应的引脚。然后，在UART2_SendFrame函数中，我们通过循环将数据逐个发送到UART2模块的发送数据寄存器中。在UART2_ReceiveFrame函数中，我们通过循环从UART2模块的接收数据寄存器中逐个接收数据。在主函数中，我们定义了一个示例的8字节数组txData，并将其发送到UART2串口。然后，我们通过UART2_ReceiveFrame函数接收UART2串口的数据，并将其存储在另一个8字节数组rxData中。最后，我们检查接收到的数据是否与发送的数据相同
