Re: [Haskell-cafe] Embedded haskell?

Another option would be to use Atom. I have successfully used it to target the arduino platform before. Running the entire OS on the embedded system seems dubious. Assuming you are using something the 9x family of transmitters -- they are slow and have very little internal memory. Plus trying to programming using a 6 buttons would be a royal pain. If you really want in-field programming, then you might at least using a raspberry pi with a small bluetooth keyboard and have it upload to the transmitter. - jeremy On Wed, Feb 20, 2013 at 1:33 PM, Mike Meyer wrote:

I've been working with open source rc aircraft transmitter software, and in looking at the shortcomings of one of them, started thinking about embedding a language. There are a number of options that can work here, like FORTH or a basic. But then I realized that Haskell - or similar functional language - could well be a good fit.

The software is meant to let the end user express how the various inputs - joysticks, switches, trims, knobs - are mapped to values the radio sends on the various control channels. All the key values are immutable - you either read them from hardware once in the process of building a frame to transmit, or you fill them into a frame and transmit it, then start over for the next frame. You just need to let the end user express the functions to go from one to the other.

The other restraint is that you need to be able to change the code in the field, with the only computer available being the embedded one. You might have a touch-screen, or you might just have cursor keys. Either way, actually inputting a program could be interesting. Similarly, the entire system: compiler, interpreter, whatever - needs to run on the embedded computer.

A quick google turns up Hume, which seems to be designed for this kind of thing, though not with the "in the field" restrictions.

Anyone have any other suggestions of software that might fit here? Experience with any of that software? Other suggestions?
