No UART of any kind on the board. Bit banged RS232 in software at 19200 baud. 38400 are possible, but I might get in some trouble with file transfer protocols at that rate.

That was the rev0 of the design, banging bits on the GPIO. Could even be more efficient.

And today I'm doing the opposite. 
Someone came up with a bit banged PS/2 keyboard port. Good idea, but of little use to me. My processor has better things to do than constantly poll for keystrokes and I also want a s PS/2 mouse. So I have drawn a little schematic. Serial to parallel conversion using latching shift registers that can be read as two separate input ports and a separate interrupt for each PS/2 port when another byte has been received.

I learned (?) to solder when I restored Grandpa's 1936 Pilot Radio. The first few times I had more scars on my fingers and hands than I did successful connections. Ouch! Even my best work was messy.
And as a follow up - do you pronounce the "l" in solder? Here is is silent.

I'd pronounce it with the L, but from now on I will start pronouncing it without

I obtained a piece of code from Internet, but can not tell which computer language is used. so I try to post here to get some hints.
it is likely C grammar, but has some unfamiliar special functions invoked:
extern bool Angle_13_1=false;
extern color Col_13_1=Sienna;
extern int Style_13_1=0;
extern int Width_13_1=1;
double EndPrice_13_1;
extern bool Draw.as.Background=true;
int init(){return(0);}
int deinit(){
ObjectDelete(AngleNum +"Angle_1_1");
ObjectDelete(AngleNum +"Angle_1_2")
return(0);}

The only language I know of that accepts '.' in variable names is R - and that doesn't look like it at all ...

Slim chance: Delphi is a modified/enhanced Pascal and they type begin and end instead of braces. I think braces are for comments if not mistaken.

Don't think so, it doesn't have an extern keyword.

I agree with you. it makes sense if that one is a struct.

It looks like MQL, or MetaQuotes Language. It's usually used for automated trading scripts.

it can be MQL too.
from this link, it seems like a C++ type of language.
never played around with this MQL...

I taught myself metaprogramming. That's kind of an issue because I have this code I wrote that I understand but can't explain to others, and when I try it tends to confuse people.
I don't think it's their fault.
Sure, maybe some of it is that metaprogramming isn't done so much day to day with C++.
But also it's because I lack the lexicon and foundation.
I'm not really sure what to do about that. Most of the material I've seen on metaprogramming leverages the STL in ways that are unavailable to me on some IoT platforms. Ergo, I wasn't going to be served functionally by learning the STL'ized version of this. I had to go to the metal, but I've never seen good material on it, except for stuff that explains the STL.
Meh. I feel like I've kind of painted myself into a corner. On one hand I can code all day like this, and I love the flexibility. On the other hand, I think my code might be something of a black box when you dig into it.

You should try some Rust. I'm serious. I cut teeth on C++ (and a dummies book) in 1993 or so & I used C++ (a lot via MFC) for many years until C# really took over.
I think C# really did help to make nicer/gentler/prettier code for the most part. But of course that is because it had the privilege of being further from the metal in most cases.
Anyways, I recently wanted to see what all the fuss about Rust was so I picked up the fantastic book, The Rust Programming Language (Covers Rust 2018)[^] (No Starch Press) and started into it.
I built a little app (GitHub - raddevus/watcher: File System Watcher implemented in Rust - can watch events on directories & tail files (continuously watches files or directories)[^])which allows you to watch any part of your file system & runs natively on any OS. That's a very cool part.
Sidebar - You can learn a lot by watching what files are accessed by the system.
My Real Point -- And I Do Have One
Ok, but my point is that the things the Rust language developers have done to "fix C++" are amazing (though at times feel annoying & confusing when you are first learning) and they give you a new view of what Programming Languages are really trying to do and how many things were actually done improperly in other languages.
Being a C++ developer makes the experience of learning Rust far richer. I think you'd really like it.
Check Rust out and let me know what you think. Also, let me know what you think of my little file watcher app.

Will do. I've been meaning to but I've been doing so much IoT stuff these days I haven't had the chance. Rust doesn't target the hardware I target.

That's a good point. Now you got me thinking if anyone is working on that -- thinking how gnu toolchain could be leveraged to take Rust and build for different MCUs??? That wold be cool.
Someone is probably working on it.

Do you really have to explain your code to anyone else? You usual way to is provide an API, document the classes and calls, and call it a day. Since, as I understand it, you are providing a library, that should be sufficient.
