So the need exists to put a fancier interface on a cosmetic laser designed about 15 years ago. I first thought of a Cortex M3 system designed from scratch, but that seemed a lot of work, so how about some SBC which talks to the existing HC11 board and does the LCD and touch screen.
Right now the HC11 has a 64 x 240 b/w LCD with the T6963 controller and 5 push buttons
The x86 PC type seemed expensive and probably overkill anyway, but the ARM types seemed cheaper and with prices ranging from $150 to $1500, seemed a go , so I ordered the Mini2440 at $150 with the 7" VGA 800 x 600 display(well $195 including the SDK). Documentations seems sketchy and i dont speak Chinese, but I find it totally impossilbe I can try something more expensive. I know nothing whatever about Linux and it seems for what I want to do I don't need an operating system at all, but an OS provides a layer of abstraction so that when the board I have chosen goes away, it will not be too incredibly difficult to port the code to another board that runs Linux . It arrives and the first issue is to find a computer that reads a DVD and has a serial port, which is generally mutually exclusive. For one I can see no reason to run Linux on the host.
