Scrolling List on MD-HMI
« on: December 10, 2003, 03:45:35 AM »
I am setting up a T100MD888 with MD-HMI display to control an induction tool heating device we manufacture.  About 40 different tool types are processed, each requiring different settings for heat time, power level etc.  Each tool will be assigned a number which when input will set these parameters.  I would like to set up some kind of scrolling list on the LCD that would enable the display of all 40 types of tools with their ID numbers.  The user could then review the list to pick out the correct ID number for the tool he is heating and input it.  Is there any way to do this?

The LCD does not handle scrolling automatically. You will need to control it fromwithin your program. Basically you use a variable as an index (e.g. N), and when you press the scroll up/ scroll down button you will increase or decrease the value of N by 1 until the limit is reached. Then your custom function that display the tool list will have to use the value of N as the beginning tool number and display the list up to the maximum number that can be displayed on a single 4 x 20 screen. This should be quite easy to achieve.
