Amazing content! And I have only just started watching.

Hi, I came across this. I'm building a Raspberry Pi Zero 2W emulator. Can the same library be used for it?

Genial! Muitíssimo obrigado Urish. Não conhecia esse projeto do tawjaw, ele me deu algumas ideias para soluções das aulas remotas. Se conhecer outros projetos similares, ficarei muito feliz de receber indicações.

How to get the exact desired delay?

Great video

Are any of these simulators capable of allowing user to stick the Boolean Algebra equation(s) of one's design, then spit out the schematic?

nice

Mind blowing video. May god keep you happy and healthy.

Uri Shaked is a true genius, I always say this. Mr. Shaked has changed my life, I can not thank you enough sir, I am very grateful for everything you have done to teach us your knowledge and wisdom.

Really great content, helps a lot to understand stuff!!

Great. You saved bytes you don't even need in this case. The code is terrible and nobody understands it anymore. Whatever. Nice expert insight that most people never need.

hello from discord

I've no doubt that to those who are familiar with this, it all makes sense, but for me who is still trying to learn this it is way way too fast. Please can you do something that is a little more sedate for us mere mortals.

how you Know all this information :)

simple great tutorial! keep doing it...

as an ad-on, for paying customers, add on a chip supplier data base and market portal; new (with chip place of origin) and used (ditto, as so many come from China). Your logical area of development then would be into hardware for setting and soldering on chips and board chip removal for the used market. Further hardware would be automated chip testers. Grinding up chip is so anti-productive from at the very least the energy perspective. I see this tool as a good start to get the electronic cottage industry going.

He lost me at designing his own chip! LOL

Can I2C Communication Components such as LCD 12C or Oled use this port manipulation?

Your 158 bytes are not the end. This one uses 80 bytes only and 0 bytes dynamic memory: int main() { DDRB = DDRB | 0b00001000; while (1) { PORTB = PORTB ^ 0b00001000; // flipping 1 pin only for(long i = 0; i < 500000; i++) { asm(""); } } }

From the arduino IDE it can easily be done in 148 bytes by using a smaller counter variable i of 3 bytes: int main() { // ========== Setup ========== for (;;) { // ========== Loop forever =========== PINB |= 1 << 5; for (__uint24 i = 0; i++ < 3000000;) { asm(""); } } // ================ Loop forever =========== }

Is it possible to do biometric simulation like palm, face , iris or fingerprint into wokwi simulator??

The active waiting saves space but definitely is not optimal in terms of energy consumption

My dude dropped us off at Arduino code Dropped us into C code Then he optimized us with some ASM 😂 🫡🫡🫡 my hat is off to you sir, FANTASTIC Explanation for memory save. Keep up with the ASM tuts….it’s a dying breed, but this is a fantastic platform to teach it on. Everyone wants to “talk to the metal” 👍

Im wondering why PINB can be assigned with the value. I thought it was read only ;)

There are AVR app notes that discuss this topic and compare loops and code structures with each other on speed and size. You can search for: 'Atmel AVR4027: Tips and Tricks to Optimize Your C Code for 8-bit AVR Microcontrollers.' Prettified code is not necessarily faster, but repeating code is also not smart.

Hello, This was something I hadn't seen before. Writing PINB toggles all bits (i.e. 0xFF). That part wasn't clear from your narration, "totals the pins". PINx is considered a read only register in Atmel docs. Thanks.

Greate video

Dude, if you were teaching them how, so many more people would want to learn code and hardware. You're a delight to watch.

wokwi is wonderful， but web simulation is a little slow， why there is not an exe file running in windows or linux

Keren om, penjelasannya sangat bagus👍

Tank you

I am trying to read a analog value and print it in chip console. I get the value as either 0 or 5 instead of other values. Is there any other way to do it?

Спасибі за ще один хороший огляд! Єдине: маленька одруківка в назві відео: ''Я там Катя?", хоча це надало цікавої ''фарби'' назві цього фільму.

I am trying to make an analog read circuit for custom circuit. Is it possible to do it? The value(0-255 or 1024) should be printed in the chip console.

Smaller but at what price? Readability, which directly effects maintainability! Part of the purpose of the Arduino IDE is to make programming easier, especially for the beginner. There are plenty of microcontrollers on the market so if you need more memory or more speed buy a different one. If one needs to minimize size then write the code in the assembly language for the target device and document it well but don't expect it to be easily understood by a wide audience.

I would really like to see an demonstration on how much of a speed gain we can achieve as a result of these kind of optimizations.

It would be interesting to see how this could be adapted to work with the new Arduino UNO R4. It is not based on an ATmega chip therefore the registers are different and from what I could see also the execution of instruction is rather different. I tried to apply the same concept presented in this video using the General Purpose Timers but I could not obtain a working example. Maybe you are able to do it having more experience in the field.

How to convert a readable code into a nightmare

What about incresing code? 924 bytes is preloaded arduino.h content, which will be used for building bigger code.

Muito bom

You did not "optimize" the easy to use Arduino code ... You replaced it with garabage.

The moment you started typing code like a mad woman/man? you lost everybody's interest in term of simplicity about Wowki.

Hi, how can I insert a simple diode 1N4004 or transistor 2N3906.

useful information, thanks

Спасибо. :) Очень интересное видео.

Great simple descriptive video. If ever redone in.a newer video: The sizing comments should include a description of what the mods were, and the operating result. Also would be nice to know what the empty loop time elapsed is, measured. You can use a stopwatch and and outer loop to lengthen the time to that which your fingers can operate the stopwatch to some good accuracy.

Is there any way to use this tool to test DC motors and or other things like 12V DC LED arrays for power consumption or circuit integrity? This popped up on my feed and looks perfect.

I want to work with Mq135 should I use custom chip for it.....?? Name mq135 for Air Quality Monitoring
