kf8a100ftn芯片的iic中断模式读取stcn75芯片代码

以下是使用 kf8a100ftn 芯片的 IIC 中断模式读取 stcn75 芯片的示例代码：

#include <stdio.h>
#include "kf8a100ftn.h"

#define IIC_ADDR_STCN75 0x48

volatile unsigned char iic_done = 0;
volatile unsigned char iic_error = 0;
volatile unsigned char iic_data = 0;

void iic_handler(void)
{
    unsigned char status = iic_get_status(KF8A100FTN_IIC_CH);

    if (status & KF8A100FTN_IIC_STATUS_ERROR) {
        iic_error = 1;
    } else {
        switch (status) {
            case KF8A100FTN_IIC_STATUS_MT_SLA_ACK:
            case KF8A100FTN_IIC_STATUS_MT_DATA_ACK:
                if (iic_data == 0) {
                    iic_start(KF8A100FTN_IIC_CH, IIC_ADDR_STCN75, KF8A100FTN_IIC_DIR_READ);
                } else {
                    iic_read(KF8A100FTN_IIC_CH, &iic_data, KF8A100FTN_IIC_READ_ACK);
                }
                iic_data++;
                break;
            case KF8A100FTN_IIC_STATUS_MR_DATA_ACK:
                iic_done = 1;
                break;
            default:
                iic_error = 1;
                break;
        }
    }
}

void iic_read_stcn75(void)
{
    iic_done = 0;
    iic_error = 0;
    iic_data = 0;

    kf8a100ftn_iic_config_t iic_config = {
        .mode = KF8A100FTN_IIC_MODE_INTERRUPT,
        .speed = KF8A100FTN_IIC_SPEED_STANDARD,
        .address_mode = KF8A100FTN_IIC_ADDR_7BIT,
        .address = IIC_ADDR_STCN75,
        .direction = KF8A100FTN_IIC_DIR_WRITE,
        .data = 0,
        .count = 1,
        .callback = iic_handler
    };

    iic_init(KF8A100FTN_IIC_CH, &iic_config);
    iic_start(KF8A100FTN_IIC_CH, IIC_ADDR_STCN75, KF8A100FTN_IIC_DIR_WRITE);

    while (!iic_done && !iic_error) {
        // Wait for IIC transaction to complete
    }

    if (iic_error) {
        printf("IIC error occurred.\n");
    } else {
        printf("STCN75 temperature: %d\n", iic_data);
    }
}

int main(void)
{
    iic_read_stcn75();
    return 0;
}

该代码使用 kf8a100ftn 芯片的 IIC 中断模式读取 stcn75 芯片的温度数据。在主函数中调用 `iic_read_stcn75` 函数，该函数初始化 IIC 配置并启动 IIC 读取操作。在 IIC 中断处理函数中，根据 IIC 状态机的状态进行相应的操作，直到读取完成或发生错误。最终，将读取到的数据打印输出到终端。
