Need advice on switch from BS2

FredCA

I currently have a BOE with BS2, a project that includes a servo, tachometer input, LCD display, etc. and it works. Howerer, I have run out of program space. I am using the Parallax serial LCD display, want to drive at least two servos, have a couple of relay boards activated by pin outs, monitor several pushbuttons, monitor and display a pulse input as a speed indication, want to implement P&ID control algorithms. Can someone advise if Javelin or BS2sx would be best choice. I understand Javelin would require re-program, but BS2sx need to deal with program banks and pass values back and forth. I am about mid-way in project development, most hardware is done, but a lot of software yet to go. Would welcome any thoughts. Thanks.

You probably want a Javelin. The flat memory model saves a great deal of agony. The BS2sx may run faster, though, if you have speed constraints.

Thanks, Scott. Speed is important, but Javelin might allow me to monitor some things in the background, while on BS2sx it is mostly sequential. So maybe it would balance.
I have never programmed in Java, so might be a little learning curve.

Javalin

I'd go with the Javalin as well. I've been using it for a while. If you're running an LCD you'd be best to put the strings into an EEPROM, and retrieve and display from there. That way you avoid filling the javalin's memory with strings!
