Hai,
I am an embedded developer mainly worked on non OS programming.
Now I need to develop a project where I have to aquire data from differnet chanels and show the as bar graph and all. No high speed aqusition or processing is needed. Read some currents, voltages and show as bar graph and tabular data. the data aqusition and processing part is not a problem for me. I had external hardware from where I will read data using RS485 or CAN bus to this Single Board Computer (SBC) and show it.
The UI part means this Graph ands all, I am planning to do on a linux based SBC which can drive a approximately 8" LCD with Touch screen. On this part I have no idea about the capability of the hardware I need to show a smooth display. Cost is also an issue, the SBC should be arounf $60 -$70 to fit in the budget at the max.
Maybe you could reference following SBC:
