好的,您可以参考以下代码实现 TC264 MCU 的串口通信接收数据,数据为一个数组:
```c
#include <stdio.h>
#include <stdint.h>
#include <stdbool.h>
#include <string.h>
#include "Ifx_Types.h"
#include "IfxCpu.h"
#include "IfxScuWdt.h"
#include "IfxAsclin_Asc.h"
#define ASC_TX_BUFFER_SIZE 64
#define ASC_RX_BUFFER_SIZE 64
uint8_t g_ascTxBuffer[ASC_TX_BUFFER_SIZE];
uint8_t g_ascRxBuffer[ASC_RX_BUFFER_SIZE];
IfxAsclin_Asc g_asc;
void init_uart(void)
{
IfxAsclin_Asc_Config ascConfig;
IfxAsclin_Asc_initModuleConfig(&ascConfig, &MODULE_ASCLIN0);
ascConfig.baudrate.prescaler = 1;
ascConfig.baudrate.baudrate = 115200;
ascConfig.baudrate.oversampling = IfxAsclin_OversamplingFactor_16;
ascConfig.bitTiming.medianFilter = IfxAsclin_SamplesPerBit_three;
ascConfig.bitTiming.samplePointPosition = IfxAsclin_SamplePointPosition_8;
ascConfig.interrupt.rxPriority = 1;
ascConfig.interrupt.txPriority = 2;
ascConfig.interrupt.erPriority = 0;
ascConfig.rxBuffer = g_ascRxBuffer;
ascConfig.txBuffer = g_ascTxBuffer;
ascConfig.rxBufferSize = ASC_RX_BUFFER_SIZE;
ascConfig.txBufferSize = ASC_TX_BUFFER_SIZE;
IfxAsclin_Asc_initModule(&g_asc, &ascConfig);
}
int main(void)
{
Ifx_CPU_PSW psw;
psw.U = 0;
psw.B.A = 1;
IfxCpu_initCSA(&psw);
IfxCpu_enableInterrupts();
IfxScuWdt_disableCpuWatchdog(IfxScuWdt_getCpuWatchdogPassword());
init_uart();
uint8_t rxBuffer[10]; // 接收数据的数组
uint32_t index = 0; // 当前接收到的数据的索引
while (1)
{
// 等待接收数据
while (!IfxAsclin_Asc_getRxBufferSize(&g_asc)) {}
// 读取数据
uint8_t data = 0;
while (IfxAsclin_Asc_read(&g_asc, &data, 1))
{
rxBuffer[index++] = data;
if (index >= sizeof(rxBuffer)) // 接收完成
{
// 处理接收到的数据
printf("Received data: ");
for (uint32_t i = 0; i < sizeof(rxBuffer); i++)
{
printf("%d ", rxBuffer[i]);
}
printf("\n");
// 重置索引
index = 0;
}
}
}
return 0;
}
```
以上代码使用 IfxAsclin_Asc 模块实现串口通信接收数据,并将数据存储到一个长度为10的数组中。如果接收到的数据长度超过10,则会忽略多余的数据。当接收到10个数据时,会打印出接收到的数据,并将数组索引重置为0,等待下一次接收数据。
注意:以上代码仅供参考,具体实现可能需要根据实际情况进行调整。
