Description
This command sets the direction of up to 64 consecutive TTL-In/Outputs (8-bit
wise).

Definition
void DapiSpecialCommand(ULONG handle, DAPI_SPECIAL_CMD_SET_DIR_DX_8,
ULONG ch, ULONG dir, 0);
Parameters
handle = This is the handle of an opened module.
ch = Must be 0.
dir = (8-Bit) sets the direction for 8 consecutive TTL-In/Outputs. (1=output /
0=input)
Remarks
Not for USB-MINI-TTL8!
Use the DAPI_SPECIAL_CMD_SET_DIR_DX_1 command for USB-MINI-TTL8.
Example program
DapiSpecialCommand (handle, DAPI_SPECIAL_CMD_SET_DIR_DX_8, 0, 0x1 , 0);
// Set Dir of TTL-I/O CH0-7 to output, others to input
DapiSpecialCommand (handle, DAPI_SPECIAL_CMD_SET_DIR_DX_8, 0, 0x3 , 0);
// Set Dir of TTL-I/O CH0-15 to output, others to input
DapiSpecialCommand (handle, DAPI_SPECIAL_CMD_SET_DIR_DX_8, 0, 0xc , 0);
// Set Dir of TTL-I/O CH16-31 to output, others to input
DapiSpecialCommand (handle, DAPI_SPECIAL_CMD_SET_DIR_DX_8, 0, 0x33 , 0);
// Set Dir of TTL-I/O CH0-15 and CH32-47 to output, others to input
DapiSpecialCommand (handle, DAPI_SPECIAL_CMD_SET_DIR_DX_8, 0, 0xff , 0);
// Set Dir of TTL-I/O CH0-63 to output, others to input
