Getting Started with ESP32 - Step-By-Step Tutorial

[@gcg8821]

Retired engineer, old enough to be your grandpa. Really enjoyed your tutorial. Discussing really simple steps is critical to start the learning process. :)

[@edibandulan5266]

I just know ESP32 for camera by combine it with arduino? Actually what's the exact function of ESP32?

[@Rushil69420]

@@edibandulan5266 It's basically made for IOT applications - it's an SOC that integrates WiFi/Bluetooth so you can have multiple microcontrollers/processors, communicating with one another over your home network (or on their own private network), and controlling things via GPIO accordingly. They can also do interesting things by themselves - act as a super low power DNS server, and other things I don't understand lol.

[@yasirpunathil7143]

@@edibandulan5266 Hi, ESP32 is microcontroller. There are many microcontrollers like TI MSP430 series, NXP KM series, etc. Microcontrollers unlike simple processors come with alot of peripherals integrated into the single chip, like UART module and SPI for communication, ADCs to convert analog signal to digital values, etc. ESP32 comes with, one can say, peripherals needed for WiFi and Bluetooth communication, other than regular peripherals like UART, SPI, I2C, etc. And the processor is very powerful, plenty of memory, and extremely cheap as compared to other chips with similar features. So if you want to give your system, maybe camera, or maybe sensor system, wireless communication capability, ESP32 is a good choice

[@LrbinMT]

Using an ebay ESP32 ESP-WROOM-32 ESP-32S Development Board 2.4GHz WiFi & Bluetooth I found LED_BUILTIN didn't work, undefined; found the blue led on the board (other was a red Power LED) is GPIO_NUM_2 , changed that plus used 115200 as the baud rate and it worked. Linux Mint using the VS Code flatpak. Only changed the baud rate because I recognize 115200 not the 921600. Also used the ESP32 DEV Module. Appreciate the video.

[@onlyme0349]

we're using the same devices, thanks for the heads up

[@dave_dennis]

I was able to follow this flawlessly. You style is methodical and very easy to follow. THANKS. I have one question. How does VS code know which COM port to use to upload the code?

[@tomasztarnowski4434]

Thanks for the kind words, David. I'm glad I could help. In terms of the port detection PlatformIO loops through all the available ports and tries to match the device by hardware id/model - you can find more in this thread community.platformio.org/t/auto-detect-port-explained/16062/2. Also if you'd like to specify the port of upload you can do it by adding "upload_port = /dev/ttyUSB*" or "upload_port = COM[13]" to platformio.ini config file - have a look at this page in the PlatformIO docs: docs.platformio.org/en/latest/projectconf/section_env_upload.html#id1

[@DERKONIG12345]

For ESP8266 you keep boot pin grounded, then you ground reset (or push buttons if buttons are connected). So the mcu starts in Flash mode. It is about espressif cpu I suppose.

Can I use sample codes for ESP32 WROOM and libraries with the ESP32 - mini-c3 ??? I need to do a low power project, so that's why I'd rather used the ESP32miniC3? Thanks

[@tomasztarnowski4434]

Hi Sophia, I think it should work with ESP32 mini-c3 as long as you select the right board when creating a new project in PlatformIO however if your board is not on the list then it might be a bit more complicated and I'd suggest checking PlatformIO forum. If your board is ESP32-C3-DevkitM-1 it should work fine.

[@akhilesh7313]

[@tomasztarnowski4434]

Thank you!

[@ziri5480]

hey quick remark 1 baud means 1 symbol transmitted per second. A symbol can be more than one bit. This is why we don't have to create confusion between bps, bit per second, and baud!

[@tomasztarnowski4434]

thank you, ziri for clarification. You're right baud is more of an abstract term and what's important is the context :)

[@rafalis2]

maybe I wasn't too attentive, but I couldn't see info on which pins to plug vs. the serial adapter which was the info I was looking for. Is it the same as the esp8266 probably?

[@tomasztarnowski4434]

hey, I'm not sure if I understood it correctly but do you mean the pinout reference - like what digital pins can be used to connect an external diode or other electronic part? if so you're right I haven't covered it with this video but I can cover it in the future.

[@claytsunami8084]

This is a great video!!! Thanks for teaching me on the basics of an ESP32. One question I had is. How do you terminate the process? When I kill the terminal, the diode is still blinking and it won't stop

[@tomasztarnowski4434]

Hi Clay, the code runs on a microcontroller so it will run as long as you provide a power to it so the simplest way to "terminate" it is to disconnect it from the power source although if your goal is to be able to run and kill processes on ESP32 you can either program it so external control is possible (you can check my other videos on how to control it over WiFi/internet) or you can put it to sleep after X number of seconds (I don't have a video on it yet but I'll make one soon)

Hi. Tomasz. I repeated your video tutorial on my laptop with Linux Ubuntu operating system. But before starting the download of HelloWorld code to the esp32 microcontroller, I did't install any driver for uart-bridge CP2102 (I haven't used any boards with any CP21xx chip before on my laptop, for sure. I installed the system just a couple of months ago.). But despite this, everything was loaded and the board passed the LED blinking and sending text to the terminal. I think at the moment newer Linux Ubuntu versions already support the CP2102 chip out of the box.
