TFT Question


#1

is there someone who already got a Large TFT touchscreen Screen working with ChipWorkX? Is it possible without extra hardware ? and only the managed .NETMF library’s


#2

Not sure what you mean by large… but there is a blog post about attaching the 7’’ GHI TFT to ChipWorkX…

i was thinking more like a 15 inch touchscreen

You can use 42" LCD until it do not reach video buffer limit(960000) for example:
800x600x2 = 960000
1000x480x2 = 960000


#5

800x600 is the max resolution.


#6

This is only 10’’ but you might find bigger ones at different vendors… http://www.demmel.com/ilcd/english/cpanel1060.htm

These displays are programmed via I2C, SPI, USB or Ethernet so they are independant from the device you use to communicate with.


#7

So if i understand this i can simply control any screen through I2C, SPI etc. using the ChipWorkX board it doesn’t matter if the resolution is higher than 800X600?


#8

If you use LCD which have own LCD controler on it(I2C, SerialPort, USB or something else) you can use any resolution you want.


#9

it’s probably worth asking the follow on question: what features will you NOT be able to use with an SPI/I2C connected display. For instance I would expect that you could NOT use the native graphics / WPF capability.


#10

Bitmap.Flush() wouldn’t be available; you’d have to flush yourself. Probably want to write a whole new core like for the Panda II’s LCD


#11

thanx guys i got one more question. how about touch functionalitys. am i going to need to use extra hardware?


#12

only if you’re using a capacitive (or other than resistive) touch panel.
