trigger.model.setblock() — trigger.BLOCK_DIGITAL_IO
This function defines a trigger model block that sets the lines on the digital I/O port high or low.
Type TSP-Link accessible Affected by Where saved Default value
Instrument reset
Usage
trigger.model.setblock(blockNumber, trigger.BLOCK_DIGITAL_IO, bitPattern, bitMask)
The sequence of the block in the trigger model
Sets the value that specifies the output line bit pattern (0 to 63)
Specifies the bit mask; if omitted, all lines are driven (0 to 63)
Details
To set the lines on the digital I/O port high or low, you can send a bit pattern. The pattern can be
specified as a six-bit binary, hexadecimal, or integer value. The least significant bit maps to digital I/O
line 1 and the most significant bit maps to digital I/O line 6.
The bit mask defines the bits in the pattern that are driven high or low. A binary 1 in the bit mask
indicates that the corresponding I/O line should be driven according to the bit pattern. To drive all
lines, specify all ones (63, 0x3F, 0b111111) or omit this parameter. If the bit for a line in the bit pattern
is set to 1, the line is driven high. If the bit is set to 0 in the bit pattern, the line is driven low.
For this block to work as expected, make sure you configure the trigger type and line state of the
digital line for use with the trigger model (use the digital line mode command).
Example
for x = 3, 6 do digio.line[x].mode = digio.MODE_DIGITAL_OUT end
trigger.model.setblock(4, trigger.BLOCK_DIGITAL_IO, 20, 60)
The for loop configures digital I./O lines 3 through 6 as digital outputs. Trigger block 4 is then configured with a
bit pattern of 20 (digital I/O lines 3 and 5 high). The optional bit mask is specified as 60 (lines 3 through 6), so
both lines 3 and 5 are driven high.
