Hi, I am using the LK204-25 with keypad interface and a Javelin stamp controller to display vertical graphs and have a few question about data types.
1. Can I send double values instead of ints to be graphed? ie 1.58 or 10.62.
2. If so, could you provide an example.
3. Is data only sent a byte at a time?

Hi enwsteve,

Thank you for posting.

When drawing graphs you will be filling in pixels inside a certain range. For horizontal graphs you have a range from 0 to 20. For vertical graphs you have a range from 0 to 100. What you can do in your programming is to group the decimal numbers with the pixels. For example 1 can be a height of one, and 1.5 can be made into a height of 2. Depending on what you would like to increment by. For more detailed information on the bar graphs please refer to section 5 of the manual at http://www.matrixorbital.com/files/LK204-25.pdf . Almost anything is possible, aslong as you program it correctly.

You do not have to send one byte at a time, you can also group them. For examples of programming the javelin stamp, you can go to http://www.lcdforums.com/forums/viewtopic.php?t=938 .

I hope this information helps you out. If you have anymore questions or concerns, please feel free to post.
