Working with Docklight (Advanced)
4. Add the delay time: In this example a decimal value of 002 (20 milliseconds) after
the "&" function character is added. The sequence is now:
103 | & | 002 | 101 | 116 | 013
5. Insert a delay between all other inter-character positions: the delay character and
delay time can be copied using
Ctrl+C , and pasted in the desired positions using
Ctrl+V . Our example sequence finally reads:
103 | & | 002 | 101 | & | 002 | 116 | & | 002 | 013
Or back in ASCII Mode:
g | & |
o
| e | & |
o
| t | & |
o
| r
6. Click OK to confirm the changes
NOTE: To distinguish a '&' delay character from a regular ampersand ASCII character
(decimal code 38), the delay function character is shown on a different background color
by the sequence editor.
NOTE: The character after a delay function character is interpreted as the delay time
and is not sent to the serial device.
B) Sending the command to the microcontroller application
1. Send the modified Send Sequences using the Send button.
Docklight will send out the same data as before, but leave additional timing gaps as
specified by the delay characters. The communication display will show the same
communication data as without the delays.
NOTE: Docklight's accuracy for delay timing is limited because it has no control over
the
UART's internal TX FiFo buffer. The specified delay times for the '&' delay function
character are minimum values. Measured delay values are significantly higher, because
Docklight always waits a minimum time to ensure the UART TX FiFo buffer is empty.
Also, the
display format and the additional performance settings affects the timing. If you
have more specific requirements on Send Sequence timing and need to control the
Docklight "wait time" as well as your UART FiFo settings, please contact our

support .
Pause detection using a Receive Sequence
Docklight already offers the Pause detection... display option to insert additional time
stamps or line breaks after communication pauses.
If you require not only visual formatting, but need to define actions after a minimum
pause, or simply make sure the Receive Sequence detection algorithm starts anew after
a pause, you can add the delay function character to your
Receive Sequence definition.
In most applications the best place for the delay function character will be at the
beginning of the Receive Sequence, before the actual receive data characters. You can
also create a Receive Sequence that contains a delay/pause definition only, and no
actual serial data. This can be very useful for implementing timing constraints, e.g.
resetting the telegram detection after a pause occurred.
