Hello,

I have a MAX7456 connected to an Arduino Duemilanove and have read through the old posts (http://arduino.cc/forum/index.php/topic,8785.0.html) about programming the MAX7456.  I can get text to display and output data from a stepper motor I have connected to it as well.  What I am trying to do next is, put a crosshair in the middle of the screen.  I made a crosshair in the MAX7456 Eval kit software and saved it as a mdm file.  I can upload my mdm file through tera term and the crosshair is displayed the way I want it, but when I close tera term the image from the mdm file is not displayed anymore.  From the data sheet about the MAX7456 is says the display memory is cleared every time the power is reset.   

There is very little discussion about the mdm process in the forum mentioned above.  So my question is, how do I get the crosshairs to stay on the screen with the data I am overlaying?

Also, unrelated to the mdm topic, the stepper motor output data I have displays the degrees it is turning.  How do I get the degrees to refresh on screen with every turn it makes?  I hope that makes sense... XD

Any help with this would be greatly appreciated!
