- In this video, we explore how to setup the Espressif IOT Development Framework, or IDF, and use it to write C code to blink an LED on the board. We discuss FreeRTOS, the operating system being ran on the ESP32, and how to write code that uses the RTOS and ESP32 API's to get GPIO working. We also discuss logging data to the serial bus, and using the monitor to view the serial output.
The ESP32 IDF uses FreeRTOS, an open source real time operating system that is used on smaller embedded boards. FreeRTOS allows you to make tasks for different features on your board. Pairing this with the IDF allows you to write powerful Wifi programs to the ESP32.

How has your experience been with the ESP32 IDF? Let me know!
Not so well when trying to split the program into multiple components and driver .c files.. makefile compilation is a mess
@@colanuss4985 Use a proper IDE, like VSCode.
Never saw somebody actually using idf. Seems like the esp32 is targeted to the maker scene. That's why nobody cares about a proper build toolchain.
For me personally, I just looking into wifi and stuff via microphython for testing a small webserver.
The ESP boards got far to less pins and peripherals to be used in industry (my opinion)
No external bus controller, no DSi/LCD controller/no sophisticated timer peripheral and such
Far, far to less communication peripherals.
What's your opinion?
How to solve this error ERROR: MSys/Mingw is not supported. Please follow the getting started guide of the documentation to set up a supported environment. I am trying to run this command in Git Bash using Windows I am struct can somebody help me
I was able to resolve that error by using .bat files instead of .sh file in Command prompt for Windows if you want to program using windows use .bat files
I appreciate you showing the errors and how you work through them. I feel like that’s a important piece that most people cut out.
Very important piece. Some others just produce flawless code on first try.
You have no idea how hard it is to find a guide on how to flash your program without using an IDE. Thank you my friend
Great lesson on the IDF. Personally, I use many different modules, including the whole family of esp's, nrf and avr processors, so I enjoy the consistency of using the Arduino IDE. This IDE is simple and fast enough for switching mindsets on the various modules. With this I've programmed hundreds of IOT projects over the years and enjoy any instruction on alternate environments.
Your videos are some of the best. Thank you.
Thank you! Your tutorials are very concise and the explanations are clear and straightforward. And i3wm is beautiful!
awesome tutorial, especially the walkthrough of solving errors, thank you so much
SUUUUPER good video for real. It has everithing right. Good audio and video, the image of the board being plugged and pushing the reset button. Congrats!
Now I understand why this tutorial was so useful and on point, LowLevelLearning did it! I just started watching the first video that popped up without realizing and good for me I will get everything running like it should
Thanks a lot, this is very helpful. Getting started in this projects it's hard at first
I subscribed!!!
This has saved me a ton of time reading those ebooks.
Super awesome content.
Welcome aboard!
Great video. Waiting for part 2
Neat. I’d been meaning to check out ESP-IDF. Thanks. Awesome video as always.
Any time!
Cool video! The ESP32’s dev environment looks like it avoids a lot of headaches and boilerplate in getting things set up. Looking forward to other videos in the series!
Thanks for watching!
Its definitely more complicated than the Pi Pico or Arduino, but its also way more power.
Esp32 provides us with 2 cores which is great but in the mean time, it has relatively high latency due to the external flash that is on the board. It's great platform from IOT perspective, but not the fast one as in compare with stm32 family ucs
@@Grivious20 thats a great point. maybe I'll do a speed test some day between the ESP32 and the STM family.
@@LowLevelLearning that would be awesome !
Just what I was looking for. incredibly well explained video. My congratulations
Awesome, thank you!
@@LowLevelLearning waiting for another new video. I encourage you to do more. Thank you so much
We need more videos about it, low level idf programming esp32 please
Thank you for your great work
Just learning ESP32 IDF now after YEARS of Arduino and CircuitPython. I love this chip... so powerful and so inexpensive... it's got everything for less cost than the batteries you might purchase for it! :-D TY for this series of videos! I'm also planning to take your Udemy course.
Please consider grouping some of your ESP32 videos into a Playlist, but I was able to find everything under the Videos tab. Cheers.
Thank you Thank you Thank youuuuuuuu This was a good tutorial. Loved seeing the mistakes so that I can fix my own!!
Thank you for this tutorial!
I have done some programming for the last weeks using the Arduino-IDE and my Chinese ESP-WROOM-Board. Everything worked well, but i wanted to try to program directly in IDF cause i get an Audio-ESP in some days, and want to try to get this running as a synthesizer.
So i startet to get the VSCode to run with IDF, and it did not work. I know VS-Code, i use it to create the firmware for my 3D-printer, and the Porject-management is totaly crap.
So your tutorial to get the IDF running on my arch-linux worked very well.
I do videos about 3D-printing and desigent, and i often also do trying, create errors and talk these errors to the viewers. Many like it to see what the process of design is, but some "need" videos that are without any errors, look like all is nice and easy.
Thanks! You helped me a lot!
I find Eclipse IDF is just fine for building and configuring the project, even when splitting out to separate header files and such. FreeRTOS is the way to go.
Great tutorial. Thanks!
Great video, great name of channel and great teacher
Very high quality content
Excellent tutorial. The errors make it real!
I've been looking forward to start learning the ESP-IDF instead of using the Arduino integration (for fun and learning purposes). However I've always postponed that since I'm way too used to the Arduino platform. Currently I'm working with a project based on ESP32 and this morning I decided that I'm gonna learn the ESP-IDF and use that for this project. I was just casually scrolling on TH-cam and happened to notice your new video about... well.. getting started with the ESP32 IDF! Haha, what are the odds of that! Anyway, great video! This did get me started.
I'm very happy to hear this was useful!
Me too
what is you think about the experience worth the time?
Good Video. Learned a few things.
love your channel. thanks!
Thanks for the content
Do more with the esp32 it's pretty powerful
Nice tutorial !!!!
Do u use Visual Studio and integrate the ESP IDF extension or what kind of IDE is this?
A really good tutorial 🔥
Thanks 🔥
Thank You
Great tutorial for the nubie. What to do when things go wrong and fixing errors is all too important.
King, you know this business. Everyone can know but cannot teach, you teach.
yes pretty much like all the malakes that want to correct this dude but wont offer up their own videos. That much is true,
Thank you. :)
What is the editor you are using in the video????
The new Tamgotchi Uni uses a ESP32-S3-WROOM-1! kinda cool!
What compiler do you use for programming?
nice video, it was very useful
can you explain how to control GPIO using register addresses
I have try to look in the datasheet but I can't understand anything
At the 8m mark, why do you press the boot button after it was programmed (idf py flash )? You mention that you are holding the boot button for it to catch after using idf py monitor... then the monitor shows waiting for download.
After the flashing step, could you have just hit the reset button in order to run the program?
And if you have your ESP-32 connected to a JTAG debugger.. does that flash the board every time you debug, or does it download it (to RAM) without flashing?
Your voice is a lot like Adafruits - if you boost mid-frequencies in audio - very, very nice presentation style and voice. Good content - keep it up! I'm learning a lot.
Thank you! 😃
Hello, can you program the ESP32 to read data from 4 accelerometers?
Any chance you're working on the wifi tutorial you mentioned? Love the videos.
Not yet!
I tuned in on this clip explicitly because of the C++ in the title; alas its the same old embedded C.
Is this the git shell?
I'm a little slow here, kindly help, which command line an I copying the link into? Or rather what ide is being used?
An STM32 blue or black board with a bluetooth/wife module may be better since you could use the sm32's powerful IDE.
How to solve this error ERROR: MSys/Mingw is not supported. Please follow the getting started guide of the documentation to set up a supported environment. I am trying to run this command in Git Bash using Windows I am struct can somebody help me.
Worked good up to build at about 4:11 then the CMake error
Were you able to solve it?
@@JoaoVictor-xi7nhIt's been a while but no I never got it to work. The ESP32 just sits I have never been able to program it. I have tried in Linux and Windows with the Arduino software never been able to write to the device.
Am I missing something? There doesn't seem to be any discussion of programming the ESP32 with C++, even though the title suggests this.
What of i need to use another operating system apart from C and C++
Can you do more arm assembly video pls?
What topic specifically are you interested in?
Are you going to do more videos on esp-idf in the future?
Sure will!
@@LowLevelLearning Awesome! Looking forward to it.
Rust on ESP32?? :)
Sir I have installed the framework but got the following error after running command idf.py build
gen_crt_bundle.py: Invalid certificate in /home/santa/esp-idf/components/mbedtls/esp_crt_bundle/cacrt_all.pem
Invalid certificate
Thank you, but this is a hard task, arduion is one hander time better faster and easier.
I use it only for wifi with its default factory software and communicate with it via UART.
I am using esp32-CAM and when I get to the waiting to the download part where i'm supposed to hit the reset button (min 8:15 ) I keep getting the same message (waiting to download..) , anyone has an idea?
Wait a second, did that board have rtos already running or you compiled rtos and your program? You should explain that
The whole kernel will be built along with the application. So the whole RTOS was compiled (everytime).
is there a windows version? because i cant execute the commands
I have finish till the building ,but when i flash, system told me a fatal error occurred: MD5 of file doesn't match data in flash, but this board i flash i arduino IDE no any problem.file md5 and flash md5 not equal
I just follow you step by step, but who can tell me what's wrong with me,thanks
0:30
where is my command line?
CMD?
i get error failled to determine sizeof(time_t)
Do these instructions work for Windows?
Assuming you have cmake installed on Windows I think the build commands should be largely the same. The IDF commands should be exactly the same too.
Awesome. This was way better than using the shitty vscode extension
Nice tutorial. However from my point of view the Arduino setup is 10 times faster and easier to use. Especially if you try to use and edit the IDF samples with WiFi or BLE. It is just not worth the hassle. The code is just all over. For simple things though, where the wireless stacks are not used, it is really powerful and one get full controll over i/o:s and can speed up the process alot, compared to all the slow arduino layers of mambo. However, that really is not really the purpose with this module.
Wow 16MB/s download, what kind of Internet do You have? I'm lucky if I get 3MB/s
It's showing me cmake err, can you help me out with this
windows version?
I've been using Arduino ide, looks the same
7:01 настройкалогеров. How to fix.
I guess he forgot to release part 2 haha
That was a fairly good instruction, but I have a critique. Personally my learning style is to follow these tutorials by pausing every few seconds and following everything that's going on, then jumping around and playing a bit with what the instructor's showing me, then resuming the video. That is NOT easy when you, the teacher, are doing things like entering a broken #include and then only correcting it much later in the video. Okay, I learned something by going and solving the problem myself and then continuing, but that's fighting the tutorial rather than following it. Troubleshooting is a necessary skill but this isn't a troubleshooting tutorial, it's a getting-started and GPIO tutorial, and I think you should be providing students with reliable information in a progressive and incremental way, rather then introducing false facts and then backtracking all over the place to undo them.
Tried to install it on Windows. No fun at all...
I bet when nobody sees you, you still use Arduino IDE 😜
6:17 why are you so bad at typing?
hi in my file cant find include freertos.h why that happen thanks much
