most servers use linux

So faster that the new version of vulkan is only a syntax that get compiled to directx shaders...

what ever happened to even windows embedded?

It sucks... I know... I don't even like Windows... but it's the most used Client based OS in the world... I can't help it.

most embedded systems use RTOS

pc are personal computer

Yes they are

Give me legitimate reasons for that, opengl being hard to program or having worse performance that D3D are not legitimate reasons

so not embedded 😜

Give me legitimate reasons for that, opengl being hard to program or having worse performance that D3D are not legitimate reasons

So you said 2 reason to not use something, what do you need more?

It sucks... I know... I don't even like Windows... but it's the most used Client based OS in the world... I can't help it.

and i am saying if we take into account all the different OSes out there we would have to say a RTOS is the most common one

hell there are probably about as many phones as there are computers that run windows

and i am saying if we take into account all the different OSes out there we would have to say a RTOS is the most common one

Not all microcontrollers use RTOS...

So you said 2 reason to not use something, what do you need more?

They are shit reasons, because all GPU programming this close to the metal is hard, and D3D is not universal

and phones use android or ios or a different os of some kind

I don't go with RTOS for many microcontrollers from Microchip

Not all microcontrollers use RTOS...

however a large portion do because of the fact it is hard to write threads by yourself

I don't go with RTOS for many microcontrollers from Microchip

i thought you said you used ARM and ESP? not PIC devices

because with PIC you need more ASM then with arm or esp

i thought you said you used ARM and ESP? not PIC devices

Sometimes I have to, I even have to use basic stuff like ATMega32U4... sometimes..

for error handling the hardfaults and so on

Sometimes I have to, I even have to use basic stuff like ATMega32U4... sometimes..

this is a baby toy

as far as I know windows-gui are bloated into kernel

because with PIC you need more ASM then with arm or esp

No you don't need any ASM you can program everything in C.

as far as I know windows-gui are bloated into kernel

Kek, they used to render their scrollbars in the kernel lmao

No you don't need any ASM you can program everything in C.

you literally cannot

this is a baby toy

Yes... but sometimes when the boards are small I have to use it or even PIC18F26K22.

They are shit reasons, because all GPU programming this close to the metal is hard, and D3D is not universal

There are already HALs made to support different gpus and also HALs made by game engines or visual layers, we don't need another one

you literally cannot

I have never used ASM with PIC EVER...

No you don't need any ASM you can program everything in C.

Not true for kernels. A tiny bit of code must be asm

infact

Not true for kernels. A tiny bit of code must be asm

Sorry... I don't have to, never had to, the compiler I use takes care of everything... CCS C

There are already HALs made to support different gpus and also HALs made by game engines or visual layers, we don't need another one

Game engines build on top of opengl/vulkan/D3D, there is no other way, because these are the only ways provided by the GPU manufacturers

No you don't need any ASM you can program everything in C.

call the lgdt instruction in C

and also if you want crack a sw XD

i want to see this code

I know 8086 ASM but I don't even know the ASM for PIC.

i don't know asm unfortunately

Game engines build on top of opengl/vulkan/D3D, there is no other way, because these are the only ways provided by the GPU manufacturers

Exactly, they are build on top, they already have they abstraction, we don't need more abstraction

i want to see this code

Loading global interrupt?

Sure let me give you the code for that in C

I have never used ASM with PIC EVER...

my first fucking job with a PIC required asm due to the fact that i had to implement interrupts myself and i needed to use the shadow registers and push all the register values into a persistant location in the stack

Loading global interrupt?

no

loading a gdt table

into the intel x86_64 cpu

Loading global interrupt?

also for the bootloader

technically an x86 has a gdt table

Exactly, they are build on top, they already have they abstraction, we don't need more abstraction

That still doesn't prove that opengl is shit, because opengl is at the lowest layer of abstractions and it has the advantages of cross-platform support

into the intel x86_64 cpu

Why do I wanna do that?

Why do I wanna do that?

for making an operating system that has hardware multitasking for the intel x86_64

for making an operating system that has hardware multitasking for the intel x86_64

I don't make OS and I don't work for Microsoft or Apple to do that...

How many people do that?

I don't make OS and I don't work for Microsoft or Apple to do that...

i do not work for either company i still need to make OSes for different jobs

And we are talking about PIC and ARM not about Intel...

How many people do that?

robotics engineers should be able to make their own RTOS at least

if not they are shitty engineers

If you want to make a wheel over and over again that is your choice...

If you want to make a wheel over and over again that is your choice...

there are times when you HAVE to, most companies will even prefer you do if you have the time

Every person should be able to do whatever is needed to make their system work efficently... that is it...

because this way you can confirm yes i do fully understand the way this works

and i know how to use this effectively now

because this way you can confirm yes i do fully understand the way this works

I'm sorry I have been working for 7 years in this company and in 7 years I have made like 100s of programs for embedded systems and not once my company asked me "Can you make an OS"?

Every person should be able to do whatever is needed to make their system work efficently... that is it...

yes and this also means being able to create lightweight multitasking by hand instead of relying on a RTOS

What do you mean by "Multitasking"?

What do you mean by "Multitasking"?

having multiple tasks running at once

for example the ESP typically has 2 cores

For what? So you can run Excel and word on Embedded system?

Yes there are 2 versions ESP8266 with single core and ESP32 with 2 core...

We can program both cores to do a task in Arduino C++ using Arduino Libraries...

For what? So you can run Excel and word on Embedded system?

no so you can do several tasks for example: SENT protocol RS 485 protocol for gathering information and a CAN protocol and PWM driver

there that is 4 different tasks that is quite common for motor drivering applications

Everything is event based... I don't have to loop and see if something is working or not.

Everything is interrupt based... why should I made "Multitasking" anything?

We can program both cores to do a task in Arduino C++ using Arduino Libraries...

if you are using arduino i seriously doubt you were working for 7+ years at that company

Even Inputs are based on events.

Everything is interrupt based... why should I made "Multitasking" anything?

interrupts are slow and cause issues in microcontrollers that is why most engineers tend to NOT USE THEM

interrupts are slow and cause issues in microcontrollers that is why most engineers tend to NOT USE THEM

Wow that is news to me... Interrupts are slow? How come these are first thing to know if an event happened and they are slow?

Hi, i'm a veteran C++ programmer with 12 years of experience who is also a 30 year old virgin and wants to catch up with life

Are you for real

Wow that is news to me... Interrupts are slow? How come these are first thing to know if an event happened and they are slow?

ok say i have 2 interrupts and one has a higher priority it triggers and now i do not hear about this second interrupt

So you think 10 cycles to check if something is on buffer is faster than interrupt?

and say the first interrupt goes on for over 100 ticks
