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

@edibandulan5266 Місяць тому

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

@Rushil69420 Місяць тому

@@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 Місяць тому

@@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

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 2 роки тому

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

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.

Hey, thanks for confirming this with ubuntu. Looks like the most popular Linux distributions support CP21xx out of the box :)

@tomasztarnowski4434 Рік тому

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)
