Have you heard of the Arduino? It is the name given to a range of open source hardware designs using Atmel's microprocessors.
In the limited extent to which I have had to use embedded processors in my work, apart from on use of an 18 pin PIC processor years ago, which was programmed in assembly by someone who was used to PIC assembly, from my flow chart, I have used Atmel processors. Now I have to design something that is high value, and probably destined for low volume production, and which is as complex as anything I have designed single handedly. It needs a processor, and maybe a later model will need a screen, though the first model only needs a row of indicator lamps and a three digit power readout.
It seems very likely that an Arduino, probably the Mega 2650, will reduce development costs and time, though I may decide to program it in C rather than using the Arduino language. Timing of one event needs a response within 500ns *absolute maximum*, so at least one of the interrupt service routines needs to be efficient. I could even start on some of the software while waiting for the printed circuit boards full of power electronics to be made.
Arduinos are typically designed with connectors that allow peripherals, called "shields" to be fitted. There is one with an OLED graphic screen and a mini joystick on it - probably suitable to control the model of machine that needs a screen and more advanced menu options.
Since I first learned of its existence maybe 2 or 3 years ago, the Arduino has seemed like a solution looking for a problem, for my applications. Now it looks as if there is a problem that it is the solution for.
I was interested and amused to see "Lillypad" Arduino hardware, intended to be sewn into clothing. There are several peripherals available, and even conductive thread. Who can think of something silly to do with it?
