it's cool how simple lua is but there's all this sweet metatable stuff that lets you add complexity if you want it

yeah, it's basically like if you took all the lovely parts out of javascript

yeah but I could also just stick with lua, seeing as it's already super great.

maybe it's just x86/my env, but freertos was a pain in the rear end to build and i had to write a lot of asm to make it play nice with my other tools

eCos build isn't perfect, but it's a lot smoother than freertos. also has the nice GUI config manager to set it all up, like you've got checkboxes for FPU support, the different schedulers, etc. compiles to a library that you link to when you build your content and anything that you don't use gets trimmed then. also has a POSIX layer so it's easy to write for.

it's probably x86. I've used freeRTOS on a few ARM projects and I never had to do poo poo to get it to play nice.

no they just make people write dumber libraries.

so it turns out that, besides the weird semi-hungarian notation names for its internal funcs and the part where you specify task stack in words rather than bytes, freertos is actually really nice, and as a bonus the sprintf implementation it provides is way waaaaaay nicer than gnu sprintf

like I said, it never gave me no guff.

EFM32 isn't any harder to work with than AVR, if anything having a unified ROM/RAM/peripheral space actually makes things a lot easier. The Arduino toolchain is hiding a lot of the Harvard nastiness from you, but it's still there beneath the surface.

what harvard nastiness are you refering to? I've worked with STM32s and AVRs a whole bunch and the biggest difference between the two is that avr-studio is a nicer IDE.

well, nicer than Ride7.

If you have a lot of const data in your firmware, then it gets copied into your RAM at reset which wastes RAM. You can stick it into flash, but then you have to remember to either use pgm_read() and friends, or remember to use a different, flash-reading version of basically every libc function that takes a pointer.

it's the same with an STM32 though. You just don't have to use flash so much because you have more ram.

oh and HID is a goddamn nightmare to work with, everyone does it all wrong in new and unique ways.

hid and cdc and numerous other things wrt usb all get taken out to the woodshed. people want to expend the minimum possible engineering effort to get from point a to point b and welp,

you would think just using regular old endpoints could be made simple at the OS level. I mean it's pretty easy from uC side.

usbchat

I think the reason most people do the CDC serial thing is because it's the only reasonably well supported cross platform solution. And even if your device is HID compliant on windows you still have to gently caress with SetupAPI stuff if you want your code to handle hot-plugging at all gracefully.

I just don't understand why USB is so much more complicated from a user-space perspective than ethernet or serial ports. I mean basically you plug a device in and you should have a file for each endpoint.

Probably because USB devices do things that files don't

well a single USB device would have to be multiple files, one for each endpoint.

At the level basically every program is written at they just take data in and spit data out. Maybe you would have to do something slightly different for isochronous endpoints, but you could still use a file as the data transfer abstraction.

USB is indeed no less complicated from user space if you're interacting with a standardised device class than a TCP/IP socket is, in fact it's probably a lot less complicated, depending on what kind of device you're dealing with (inputdev in win32 is just aggressively poo poo)

If you want to actually send raw ethernet frames though then lol

CDC seems to me like a huge abstraction inversion, though. USB has a lot of really nice things in it like out-of-band control messages with a consistent structure, as well as the fact that USB is datagram-oriented instead of byte-oriented in general. CDC also isn't supported well under Windows at all, Linux gives you a /dev/ttyACM easy as pie, but then who gives a gently caress about Linux (also libusb under not-Windows is even more straightforward than a tty, do a libusb_open_device_with_vid_pid, maybe acquire the interface you're working with to disconnect the OS class drivers and you're good to go).

USB. I like making USB devices, they're pretty cool.

I've never had much of a problem with CDC under windows. Just pops up as COM whatever. HID also does ok, and you can register hooks which notify your program on plugin/removal.but yeah I wish libusb didn't suck on windows.

USB devices are pretty fun to make though.

also js and lua probably don't have bigints because bigint arithmetic is slower than float/double arithmetic

I think the idea is that since these are languages for "small programs" having different numeric types would confuse people. poo poo like: "How come 1/2 doesn't equal .5"

I mean, it's a bullshit reason, but that's what I think was going on at the time.

haskell has the nicest syntax of any language i've seen but maybe i'm biased since i use it a lot

the indentation gets a little screwy don't you think?
For example the state monad from LYAH:

code:

instance Monad (State s) where  
    return x = State $ \s -> (x,s)  
    (State h) >>= f = State $ \s -> let (a, newState) = h s  
                                        (State g) = f a  
                                    in  g newState

it's kind of annoying that everything after the let block has to be indented way the gently caress out there, I don't know though I haven't done much haskell maybe you could clean that poo poo up by putting the let on a new line.

a list is a sequential series of elements indexed by numbers. if you try to insert something into an index that isn't a number it should tell you to gently caress off instead of magically changing into something that sort of works like a list but isn't. if you do that then you're php level stupid.

Oh you are mad that tables aren't strictly arrays. Maybe that's why they didn't call them arrays.

are you saying [1,2,3,nil,5] has a length of 4? because that sounds nuts

nope, that has length 5 and will return 5 if you use the length operator.

To be more clear the literal {1,2,3,nil,5} will have length 5.

however you can screw it up by doing x = {1,2,3,4,5} x[4] = nil. That will come back with length 3. It is an annoying aspect of tables.

I'm as big a lisp dork as anyone, but if you're seriously considering sticking a scripting language into your system to let non-programmers try to program then you should probably go with javascript which at least has a large amount of documentation targeted towards idiots.

can we put a scripting language in and only let programmers use it?

node.js has a concurrency model? I thought it was strictly a single threaded event loop, and if you wanted concurrency you had to do multiple processes.
