hi,
I'm trying to make this project from Experimental Avionics.
http://https://www.youtube.com/watch?v=emqc_vi7-Rg
The original project uses a GLCD with a 192x64 resolution while I am using a 128x128 GLCD screen. I managed to changed some X,Y coordinates to suite a 128x128 LCD.
The problem is I am having difficulty in changing the X,Y coordinates in the MENU setting using an encoder. (see attached photo)
it consists of 3 settings EXIT, CLOCK, MIN. AIRSPEED
here is the code from the site
void Menu() {
int SettingItem = 0;
int ButtonPush = 0;
int KeepLoop = true;
int KeepLoop1 = true;
int KeepLoop2 = true;
int encCurrentValue = 0;
int highlightwidth = 192;
int highlighthight = 10;
int textShiftX = 4;
int textShiftY = 10;
int MaxSettings = 3; // number of setting items
byte second, minute, hour, dayOfWeek, dayOfMonth, month, year;
int secvalue = 0;
int TimeSetPosition = 0;
String StringSetting1 = "";
String StringSetting2 = "";
int tmpValue = 0;
int tmpMinValue = 0;
int tmpMaxValue = 0;
int i = 0;
GLCD.ClearScreen();
//****************************** Draw the screen ********************************
i = 0;
textAreaSetting0.DefineArea(textShiftX, 1 + textShiftY * i , 29, 1 , System5x7);
textAreaSetting0.ClearArea();
textAreaSetting0.print("Exit");
GLCD.InvertRect(0, highlighthight * i, highlightwidth, highlighthight);
i = 1;
textAreaSetting1.DefineArea(textShiftX, 1 + textShiftY * i , 29, 1 , System5x7);
textAreaSetting1.ClearArea();
//textAreaSetting1.SetFontColor(PIXEL_OFF);
StringSetting1 = "Clock: ";
textAreaSetting1.print(StringSetting1);
i = 2;
textAreaSetting2.DefineArea(textShiftX, 1 + textShiftY * i , 29, 1 , System5x7);
textAreaSetting2.ClearArea();
StringSetting2 = "Airswitch Min Speed: " + String(MinFlightSpeed,DEC) + " Kts";
textAreaSetting2.print(StringSetting2);
