hello
i am using LCD 5" SSD1963 TFT Display 800x480, arduino mega2560 mcu and Display 5 inch TFT Arduino Touch Shield w/SSD1963 for Mega/Due
also i have successfully interfaced FLASH IC W25Q128FV and display image on utft from flash ic
i am using Rinky-Dink Electronics libraries for UTFT and flash
now i am designing GUI for temperature and level controller,which have 3 pages (1)logo page(2)home screen (3)parameter set screen 2 and 3 screen have gauge meters as per attached image, images are made using photoshop
now here my question and problem is:
1)how can i draw smooth and fast needle?
i made needle image (size=71x68) and converted to array and placing that image at different
angles using
myGLCD.drawBitmap(97, 325, 71,68,small,i,53,17); function for needle image drawing but it is not
moving very fast
its angle range is from 0 to 270 degree
also i am erasing previous value needle image using background color
but all these drawing is visible on screen
(2) does mega2560 can place image with fast speed?
(3) any other way to do this?
(4) is there any thing missing in code?as per attached file
