635 programming: Cursor


New member
I was curious as to the best method for creating an underline style cursor with the 635. Right now my app is flashing a solid white square over the character it's currently on, but I'd like to have a solid underline.

The documentation indicates that there's API support for a cursor, but only on the first 2 rows?

I had considered using the 8 writeable characters in memory and dynamically updating them from a font I created, but this seems like a pain and would possibly be slow?

Thanks for your time!

You should be able to set the cursor to an underscore with "Command 12", and data of "\002".

"Command 11" is able to set the cursor to any position. I will have the data sheet updated to correct the error.

That is odd. What version is returned by Command 1? I'll look it up and see if it was a bug in that version.
