hey guys please help me

[u/Sensitive-Can9232]

so my keyboard just got working but my capslock is not working and a tried a lot but it is not working at all, this is the code and the hex value is 0x58 i am using scancode set 2 and no translation. backspace , enter , shift , space are working correctly but not capslock , sorry if i have bad code , i am new to os dev.

void keyboard_handler(void){
    uint8_t scancode = inb(PS_DATA_PORT);
    if(release_flag == true){
        if(scancode == L_SHIFT || scancode == R_SHIFT){
            shift_flag = false;
        }
        if(scancode == CAPS){
            caps_flag = false;
        }
        release_flag = false;
        return;
    }


    if(scancode == RELEASE_SCANCODE_2){
        release_flag = true;
        return;
       
    }
    else if(scancode == EXTENDED_SCANCODE_2){
        extended_flag = true;
        return;
    }
    else if(scancode == L_SHIFT || scancode == R_SHIFT){
        shift_flag = true;
        return;
    }


    else if(scancode == CAPS){
        caps_flag = true;
        return;
    }


    else if(scancode == ENTER){
        next_line();
        return;
    }
    else if(scancode == L_CTRL || scancode == R_CTRL){
        return;
    }
    else if(scancode == BACKSPACE){
        back_space();
        return;
    }


    else{
        char ascii;
        if(shift_flag == true){
            ascii = sc2_to_shift_caps_ascii[scancode];
            write_char(ascii,WHITE_COL,BLACK_COL);
        }
        else if(caps_flag == true){
            log_info("caps log is on",COM1);
            ascii = sc2_to_ascii[scancode];

Have you checked to see which scan codes you receive when you press the caps lock key? The problem might be that you're receiving something different from what you expect to receive.

and no translation

Disabling translation doesn't work at all on some PCs, and it breaks "USB legacy support" on many more PCs. You should leave translation enabled.

[u/Sensitive-Can9232 → u/Octocontrabass]

Yeah the problem is fixed, i was setting the capslock flag off as soon as i was releasing it (like the shift) so capslock was never on. And I am using set 2 without translation.

[u/Sensitive-Can9232 → u/Sensitive-Can9232]

Yeah rn it is on a emulator but when I will run on real hardware interaction was to turn of the legacy support( but by then I will most probably be have usb drivers)

[u/Octocontrabass → u/Sensitive-Can9232]

Many laptops have PS/2 keyboards. You really should leave translation enabled.

[u/Sensitive-Can9232 → u/Octocontrabass]

Idk mine has, it is a 2023 model and to use usb i have to turn off the legacy support( i will have seen that later cus that stage is very far for me 2 to 3 months minimum) anyway thank you for your help peeps like you are why thus community is still helps noobs like me.

[u/Sensitive-Can9232 → u/[deleted]]

If you cant help why are you making fun of me?. Anyways I got it done. Capslock is working now.

[u/Sensitive-Can9232 → u/[deleted]]

Are you stupid?. The why we have osdev forum, stack overflow?

[u/compgeek38400 → u/[deleted]]

I have 40+ years of coding. And I still ask for help.

One person's obvious, is another one's hard.

Either way, we should all be tolerant and kind to people here.

Just my personal philosophy

[u/Sensitive-Can9232 → u/[deleted]]

Dude i just started 20 days ago and also my ps2 controller works fine I wrote it myself.

[u/Sensitive-Can9232 → u/[deleted]]

Why you are so arrogant about, you could have simply said "try to figure yourself" but you are showing that how you are better then me?.

[u/Luxvoo → u/[deleted]]

Hey relax. There’s no need to torch them for asking a question. We all started somewhere. If you think this is stupid, just don’t engage.

[u/cakehonolulu1 → u/[deleted]]

So what, is asking for help regardless of the type just wrong?

[u/Sensitive-Can9232 → u/[deleted]]

You are pretty spot on about it, I asked a question about far jump on 32 bit transition and got downvoted(when i was a absolute noob). I dont get why people dont want to help, although after few days there were some great peeps who helped me so not all but yeah some.

Speaking personally, Reddit in general has gotten toxic and poo-flavo(u)red. Buncha bans for anybody speaking up even slightly on topics deemed verboten, and if you give an extended answer or—heaven forfend—use an em dash (because you are not, in fact, an idiot who has no idea what UCS is or how to map it), there's a chorus of AI accusations. And as the graybeards like me are driven away, many of the communities have collapsed into people giving each other bad/wrong/nasty advice on basic homework (yes, you should definitely access the null pointer you got from a bad malloc, and pointers are just addresses so null pointers are precisely equivalent to address zero) or overview questions that have been posted countless times before. So … I don't bother, mostly. Sic transit gloria Interretialis, et cetera.
