Notification before use

Depending on the type of product you are using, the definitions of ‘Parameter’, ‘IO Logic’, ‘AxisStatus’, etc. may be different. This example is based on ‘Ezi-SERVO2’, so please apply the appropriate value depending on the product you are using.

Example)

FM_EZISERVO2_PARAM          // Parameter enum when using 'Ezi-SERVO2'
FM_EZIMOTIONLINK2_PARAM     // Parameter enum when using 'Ezi-MOTIONLINK2'

1. Get IO level

bool GetIOLevel(int nBdID)
{
    unsigned int uIOLevel = 0;
    bool bLevel;

    printf("---------------------------------- \n");
    // [Before] Check IO Level Status
    if (FAS_GetIOLevel(nBdID, &uIOLevel) != FMM_OK)
    {
        printf("Function(FAS_GetIOLevel) was failed.\n");
        return false;
    }
    printf("Load IO Level Status : 0x%08x \n", uIOLevel);

    for (int i = 0; i < 16; i++)
    {
        bLevel = ((uIOLevel & (0x01 << i)) != 0);
        printf("I/O pin %d : %s\n", i, (bLevel) ? "High Active" : "Low Active");
    }

    return true;
}

[EN]
With FAS_GetIOLevel() function, you can read the level information for each IO Pin. IO level information is written sequentially from LSB to MSB of uIOLevel. For example, IO level information of pin 0 is written in the LSB, and IO level information of pin 31 is written in the MSB. 0: Low Active Level / 1: High Active Level

[KR]
FAS_GetIOLevel() 함수를 사용하여 각 IO Pin에 대해 설정된 Level을 읽을 수 있습니다. uIOLevel의 LSB에 0번 Pin의 Level부터 MSB에 31번 31번 Pin의 Level이 순차적으로 쓰여집니다. 0: Low Active Level / 1: High Active Level을 의미합니다.

2. Set IO level

bool SetIOLevel(int nBdID)
{
    unsigned int uIOLevel = 0x0000ff00;

    printf("---------------------------------- \n");
    // Set IO Level Status
    if (FAS_SetIOLevel(nBdID, uIOLevel) != FMM_OK)
    {
        printf("Function(FAS_SetIOLevel) was failed.\n");
    }
    else
    {
        printf("Set IO Level Status : 0x%08x \n", uIOLevel);
    }

    return true;
}

[EN]
You can set the level for each IO Pin using the FAS_SetIOLevel() function. IO level information is written sequentially from LSB to MSB of uIOLevel. For example, IO level information of pin 0 is written in the LSB, and IO level information of pin 31 is written in the MSB. 0: Low Active Level / 1: High Active Level. The source code above sets Pins 0 to 7 to Low Active Level and Pins 8 to 15 to High Active Level. (16 Pins)

[KR]
FAS_SetIOLevel() 함수를 사용하여 각 IO Pin에 대해 Level을 설정할 수 있습니다. uIOLevel의 LSB에 0번 Pin의 Level부터 MSB에 31번 31번 Pin의 Level을 순차적으로 입력합니다. 0: Low Active Level / 1: High Active Level을 의미합니다. 위 소스 코드는 0~7번 Pin을 Low Active Level로, 8~15번 Pin을 High Active Level로 설정합니다. (16 Pin)
