How do I reduce or eliminate any screen flicker I might see on the PE-HMI board running the weather panel application?
You can reduce or eliminate any screen flicker by adjusting the pixel clock rate up or down a bit. For example, the pixel clock is currently set at 1/8. If you change it to 1/7 or 1/9 the screen flicker goes away. This is most likely due to a clock frequency similarity between the back light and pixel clock such that if the pixel clock is slightly changed the 'beat' frequency goes away- eliminating the flicker.
