Toit is a modern high-level language designed specifically for
microcontrollers

Toit is optimised for live reloading on your microcontroller. Your
code runs incrementally as you write it and you get instant feedback.
Push changes over your local WiFi in two seconds and reserve your USB
cable for charging your phone. You iterate quickly, learn fast, and
build better things.

Defining functions

What if you want to say "Hello" a lot without getting your fingers
all tired? You should define a function. Calling a function in Toit
is as simple as mentioning its name. If the function doesn't take
arguments that's all you need.

hi:
  print "Hello World!"

greet name:
  print "Hello $name!"

main:
  hi
  greet "Kasper"

Toit + Jaguar = 

Jaguar is a small application developed by the Toit team, that runs
on your ESP32. It enables live reloading and lets you update and
restart your ESP32 code over WiFi.

Wireless

Update your code and restart your ESP32 conveniently over WiFi. No
need to flash over serial, reboot your device, or wait for it to
reconnect to your network.

Efficient

Change your code in your editor, update it on your device, and
restart it all within seconds.

Reliable

Updates contain compiled Toit programs that are relocated and
installed in flash on the device. Old versions are stopped and their
resources are freed automatically.

Writing a driver in Toit

Just a few lines of Toit code are needed to reap the full benefits of
the Toit ecosystem -- without having to rely on firmware developers.

Choosing Toit for your IoT project means that your ESP32-based
devices become as easy to program as smartphones: develop your app,
deploy it to the devices of your choice, and then update and
reinstall as often as needed, even on a shaky connection -- all that
while the other apps on the device keep running. Welcome to the 21st
century, IoT!
