just fwiw, swift is really good

swift reminds me a lot of scala, and I'd like to use it more as it matures

RAM is cheaper than programmer time. Stick a several MB chip upstream of the FIFO, right before the USB black box, and have it hold the overflow.

this is a prototype. i'm sticking a fat chunk of sram on the next board but until then i have no choice but misery
it isnt gonna be upstream of the fifo, its gonna be the fifo

yeah basically my ideal language would be a serious/terrible OO imperative lang that allows simple toll free bridging into a functional lang for when i want functional behaviors

well, my ideal lang would be a functional lang that allows toll free bridging into an oo lang for when i want oo behaviors

which basically sounds like C#/F# so that would be perfect if it werent for being tied to microsoft.

as far as one language being all things to all people it's swift imo. unfortunately apple has a lot of leftover bad habits that will probably prevent it being adopted outside of apple's sphere.

we made our first official code convention: no wildcard imports.

so far everyone had used whatever was their ide's (and sonarqube's) default settings, but today an ~*~opinion~*~ was expressed in the developers channel, discussion was had and then a decision was made.

i then went and created the project coding conventions wiki page with that one line in it and added the rule to sonarqube.

if the black box is working correctly (it might be, not actually sure), it will realize it is being backpressured by the device that is reading from it; its internal fifos will start to fill up, and the backpressure will move up the chain

what's the exact back pressure mechanism? UART flow control or something else?

it's a bit of a hack, but if hwfc was in use you should be setting the device to reject writes from the host when the fifo's above a watermark. set the watermark artificially low to test if the black box is sending when it shouldn't, verify with oscope traces

this doesn't really apply to hw. unless there's ram sitting on the dev kit already that would be an extensive rework on both the hardware and hdl sides

ok so ive got a piece of hardware talking over usb to a piece of software
the piece of hardware is an fpga, and its got a lil dinky fifo in it. the fifo can hold, i dunno, like 1k words
the contents of those words occasionally introduces things that happen (relatively) slowly, say a few milliseconds or more
when those things happen, the fifo might overflow with incoming words, which is really bad. it takes many words (dozens/hundreds) to set up the system state; if we lose a word, our state is corrupted and poo poo is hosed
so the system needs to say 'hey im busy, chill out'. so the piece that's taking a long time to do the slow action has to tell the piece that's feeding it data that hey hold on i need to finish the last thing; the piece thats feeding it needs to stop pulling data out of the fifo; the fifo will start to fill up, and the piece writing data from the usb device into the fifo needs to notice that the fifo is almost full. the piece writing data from the usb device then needs to stop reading data from the usb device.
at this point we hit a black box of usb device all the way up the software stack to the pc.
if the black box is working correctly (it might be, not actually sure), it will realize it is being backpressured by the device that is reading from it; its internal fifos will start to fill up, and the backpressure will move up the chain
eventually, the driver will learn it cant dump more poo poo down the pipe, so the method call that's writing data down the pipe will block until the whole system unjams, then it will finish its write and the rest of the system will go on its merry way

that's how its supposed to work, anyway
somewhere in there it doesn't

this seems bad

oh, you could artificially simulate this

add a command that just echoes the index into the return buffer. have host software sitting above the black box track how much buffer usage it's expected to consume with each command, make sure there's enough buffer for commands before sending, don't assume any rx in between

raminasi: Jan 25, 2005; a last drink with no ice

the reason I do not find f# useful is that you are not allowed to have reference cycles between types unless they live in the same file, and your project organization must be "a list of files" because the order of the list matters. it's like writing c without forward declarations or extern

also i always liked this thing in nunit where you can push different cases through the same unit test body, i dont think junit or mstest have anything this neat

code:

[TestCase(1, true)]
[TestCase(4, true)]
[TestCase(5, false)]
[TestCase(-6, true)]
public void IsLessThanFive_GivenInput_GivesExpected(int input, bool expected)
{
    IThing myThing = new Thing(input);
    var result = myThing.IsLessThanFive();
    Assert.AreEqual(expected, result);

well, sorta. you can't really write a large thing in pure f#, but you can write a large .net thing made up of smaller pieces that all happen to be written in f#. using c# to glue together f# libraries with all of the interesting logic seems like the way to go.

I don't even edit code INSIDE visual studio, I use it more like a debugger, I feel like it's pretty good for that and everyone should try it. it doesn't need to replace everything you already use

for the average windows programmer creating average windows programs the solution model works fine - it compiles each file then links them into whatever your output file type is

however you can have vs run your makefile instead of letting it make its own build decisions
