search for your micro-controller name + gui, example: - TX19A + gui: first result should be Toshiba's own dev environment; - STM32 + gui: first result should also be STM own site

Your original question was how to draw graphics without using opengl and using system calls. If you want to do it on a bare metal system then why mention opengl or system calls in the first place?

Hello everyone i want to ask a question, I know maybe it’s not meaningfull for this group but, i have some doubts. Do I need to graduated from software engineering field to do software project? Associate degree is not enough?

Because i understanded that i cant use syscalls

Where is the micro controller

Hi guys , i have a question could anyone could help me to get that one answer?

Write a program in Javascript (or any other programming language of your choice, or even pseudocode) 1. Write a function called do_allocation(number_of_people, number_of_buses) 2. The function should return a list of number of people who can get into the next bus that comes in based on the following logic: 3. Each bus's capacity is the sum of the capacities of the previous two buses. 4. Once all the people get in, then the buses can continue, but will have 0 people inside it. -This is the case when the number of people are less and there are more buses. So after all the people are already boarded, then the remaining buses will have 0 people boarding. 5. The output of the function is an array/list with the same length as number_of_buses. 6. The total of this output array/list should be less than or equal to the number of people. 7. The first bus' capacity can be set to 1 by default. E.g. Def do_allocation(number_of_people, number_of_buses): .... Your code.... Return array[number of people got into first bus, number of people got into second bus,.... number of people who got into last bus]

Like if anyone could tell me it's logic how to solve it

i assumed you were working with one, apparently you're not

if you have no OS you don't have syscalls, i noticed you mentioneed BIOS early, without the OS what you have are "BIOS Interrupt Calls" if you want to learn how to make one maybe look into coreboot and it's documentation

😩😩

make list that include the capacity of the first two buses declare a function that take the list and a counter (to keep track of the next available index in the list) as parameters the functoin should append the sum of the previous two elements to the list call it as many times as you want l, no problem

Because someone decided that would be their name

also you should increment the counter at the end of the function

the value in the last element in the arraylist is the capacity of the next available bus

Why they are called interrupt calls

Hi do you know what is the message bus

because they rudely interupt the operating system or bios from doing their jobs 😜

a way to send signals between two programs running at the same time

But when you call the interrupt instruction the rest of the things stop

Can it be like from the java code to the c code

Can it be like from the java code to the c code

with functions calls the process or program you are running will execute the instructions in that function but with interupts you are sending a request to the operating system (or bios) to do some thing and the bios or the OS will do it for you

basically it is a way for any two processes communicate with each other

And if it is only one instruction how you tell what to do

in x86 assembly it is: int [some specific code]

I think you have to use: ASM{ int $[bios code] }

And what is bios code

How to use malloc in c programming?

it is more like an id for the task that you want the bios to perform for your program you can read about bios routines and interupt calls here in the interupt table section: https://en.m.wikipedia.org/wiki/BIOS_interrupt_call

It is like a syscall

a system call is a interupt for the OS there is litterally no difference execpt that bios and different OSes uses different codes and registers

But is the syscall implement in a library

yes also in assembly there is a pseudo-instruction called syscall but it is actually an interupt behind the hood with C you can make system calls but I don’t think this work on bios because in 32-bit protected mode bios interupts are not accessible note that C only support 32-bit protected mode not 16-bit real mode

Why in the bios you can use only 16 bit registers

because you haven’t switched to 32-bit protected mode

Why protected

because each program runs on your machine won’t share memory with other programs or the operating system so it protects your memory and separate it

And in what library are syscalls implemented

because each program runs on your machine won’t share memory with other programs or the operating system so it protects your memory and separate it

#include <sys/syscall.h> then you can use syscall() function

because each program runs on your machine won’t share memory with other programs or the operating system so it protects your memory and separate it

i mean the open call for example in what so file is implemented

what operating system are you using?

linux

do you know what is a pipeline

what kind of pipeline do you mean?

I geuss it means interprocess communication where two processes can communicate as I told you earlier

But you are not sure
