Of course we can transfer the measurement data to a PC over the Internet and use the plotting facilities on the PC to graphically show the data but it may sometimes be interesting to show the data also on the micro-controller without the need of an Internet access. This can be done with TFT screen sensors. The one we will use has a resolution of 128*128 pixels and text as well as simple pixel based graphics is possible with these devices. |
