Programming example

Script with a for loop
The following script puts a message on the front panel display slowly — one character at a time. The
intent of this example is to demonstrate:
•
The use of a for loop
•
Simple display remote commands
•
Simple Lua string manipulation
When creating a script using the TSB Embedded, you do not need the shell commands loadscript
and endscript, as shown in the examples below.
Example: User script
User script created in TSB Embedded
display.clear()
myMessage = "Hello World!"
for k = 1, string.len(myMessage) do
x = string.sub(myMessage, k, k)
display.settext(x)
print(x)
delay(1)
end
