5.5. Set TTL-In-/Outputs direction with DapiSpecialCommand
5.5.1. DAPI_SPECIAL_CMD_SET_DIR_DX_1
Description
This command sets the direction of 8 consecutive TTL-In/Outputs (1-bit wise).
Definition
void DapiSpecialCommand(ULONG handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1,
ULONG ch, ULONG dir, 0);
Parameters
handle = This is the handle of an opened module.
ch = Must be 0.
dir = Specifies the direction for 8 channels (1=output / 0=input) / Bit 0 signifies
channel 0, Bit 1 channel 1 ...
Remarks
Only for USB-MINI-TTL8.
Use the command DAPI_SPECIAL_CMD_SET_DIR_DX_8 for other TTL-
modules.
Example program
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
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x80 , 0);
// Set Dir of TTL-I/O CH7 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0x0f , 0);
// Set Dir of TTL-I/O CH0-3 to output, others to input
DapiSpecialCommand(handle, DAPI_SPECIAL_CMD_SET_DIR_DX_1, 0, 0xff , 0);
// Set Dir of TTL-I/O CH0-7 to output, others to input
