函数
int32_t	VkDaqCreateMIChan (const char *task, const char *chans, const char *reserved1, const char *source, uint32_t maxVal)
	创建MI通道

详细描述

函数说明

VkDaqCreateMIChan()

int32_t VkDaqCreateMIChan	(	const char *	task,
		const char *	chans,
		const char *	reserved1,
		const char *	source,
		uint32_t	maxVal
	)

创建MI通道

数据类型	参数	说明
const char*	task	任务名.
const char*	chans	通道列表，多个通道之间使用逗号分隔或使用冒号指定连续多个通道，如"dev1/MIN1,dev1/MIN2", "dev1/MIN1:2"等.
const char*	reserved1	保留.
const char*	source	杂项输入源，如"VirtualCounter","Counter1","Counter2","Counter3","Counter4","Encoder1","Encoder2"等.
int32_t	maxVal	杂项输入源的最大值.

返回

成功时, 返回值 >= 0

失败时, 返回为负值的错误编号.获取详细信息,请调用 VkDaqGetLastErrorInfo

int main(int argc, char* argv[])
{
    const char* task = "task1";
    const char* source = "VirtualCounter";

    int32_t result = VkDaqCreateTask(task);
 
    result = VkDaqCreateMIChan(task, "dev1/DIN1", "", source, maxVal);
 
    if (result >= 0) {
        printf("Successful\n");
    }
    else {
        printf("Failed\n");
    }
