Continuous Monitoring of Parameter using Virtual Circular Graphical Chart on TFT Display

Ashutosh Gajare, Omkar Borikar, Saurabh Gaikwad, Vrushali Raut


Continuous and real time monitoring of a specific parameter is necessary in a variety of industries such as food processing, blood bank, rubber industry, poultry etc. The representation of this parameter needs to be done in user friendly form. This paper presents the methodology that needs to be followed to represent the parameter using a virtual circular chart of 468×466 pixels on a TFT display 800×480 pixels. The development is carried out using MPLAB tool and results are presented accordingly.

Keywords: Data logging, line drawing algorithm, polar co-ordinates, virtual circular graph.
