Programmierbeispiel
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x01 , 0);
// Set Dir of TTL-I/O CH0 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x02 , 0);
// Set Dir of TTL-I/O CH1 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x04 , 0);
// Set Dir of TTL-I/O CH2 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x08 , 0);
// Set Dir of TTL-I/O CH3 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x10 , 0);
// Set Dir of TTL-I/O CH4 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x20 , 0);
// Set Dir of TTL-I/O CH5 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x40 , 0);
// Set Dir of TTL-I/O CH6 to output, others to input
