The FLorida IoT Days has been going on for the last 6 years.
Originally started by MiamiJS back in 2016 as part of the global NodeBot Days.
We have been making blinking lights in the real world while writting NodeJS/Javascript for a long time and it's still continuing.
We usually have kits you can use that include:
- a ESP8266 board (flashed )
- bread board
- LED Lights (many)
- switches
- dimmers (variable resisters)
- Lots of wires We make them do magical things!
Originally we were using the Johnny Five Framework to make our laptops running node connect and control arduion devices to blink those lines.
But we have since then changed to "Espruino" because it's real javascript running on the actual micro controllers.
We have kept our code and notes if you wish to follow the way we use to do it and kept them in our johnny five Repo should you wish to use it or check what we use to use.
Sometimes we want the latest Espruino Software running on our ESP8266 or ESP32 devices.
To achieve this we need a couple of things.
You'll need to download the ESPTool for your OS (if it's linux or Mac make sure to chmod a+x esptool to make the binary executable)
Then the serial port that is connected to your device to do so you can go to the Espruino IDE and click on the connect icon (top right corner) then when the serial ports are listed plug and unplug your device and notice what serial port is added/removed
You'll need that to the right of the "--port" part of the script you'll be running which will be flash.sh or flash.bat depending on your decide.
Here's an example of what I had to run on my 2014 Macbook Air 11" (yeah...jelous???) that allowed me to flash my ESP8266 in 2022
sudo ./esptool --port /dev/cu.usbserial-1410 --baud 460800 write_flash --flash_freq 80m --flash_mode dio --flash_size 4MB 0x0000 espruino_2v16_esp8266_4mb_combined_4096.bin
