Exploring Rolling Text on instruments possibility!!!

[leo_83]

Hello,

 I display a string on a powersupply, eg: LABVIEW , WHERE NOTHING IS IMPOSSIBLE , but as the powersupply is limited to display (12 characters at a time), what i see on display is LABVIEW , WH ., well..!! what i thought was to keep the character string rolling on the instrument and was stuck at this point , Any suggestions how this can be done..

Cheers,

Abhi

Hi Abhi,

so you should just send 12 chars to the device. But you do this in a loop and with each next write command you increment the offset for the string subset function!
When you want to have a "rotating" text it can help to copy the first 12 chars of the string and append them at the end...

Abhi,

I think one of the early Coding challenges, possibly on the now defunct LTR, was a scrolling text display. I don't have access to my archives form home today, but you might be able to find something by searching.
