How can I reduce the power consumption in sleep mode?

One option is to define a macro the application can use when needed. A macro can turn the display off with the “v off” command. First define a special hotspot over the entire screen, then assign this hotspot to another macro. When the user touches any location on the touch screen, the assigned macro is run. The ‘wake-up’ macro could remove the hotspot and turn the display back on with the “v on” command.  A screen touch can notify the application with either a standard “x” notification from the SLCD or with a custom message from the ‘wake-up’ macro.  See the example macros in the file PowerSaveExampleMacros.txt.
