Simulate signal and serial port

[Kjulius]

Hi,

I have to control a piezo controler with its serial port. Basically, i have to create a triangle voltage signal on the X stage. To do it, i only have the command "XV<voltage>" which set the X piezo stage to <voltage>.

My first idea was to make a For loop, using loop_index*voltage_step as <voltage>, but with it I can't really control the slope (=raising speed) of the signal.

I would like to use the "Simulate signal" express vi to control easily the parameters of the signal, so i would have to convert the output,a dynamic data, into a kind of dynamic string so that i could insert the real time value in the serial command.

Do you know if it is possible, or do you have other idea to help me?

Thank you very much.
Julien.

PS: i m using labview 7.0

Use the Format Into String function, wire the simulated signal to the input (1) of the format function.
