How to configure Smick and write my first program
How to configure Smick and write my first program
In this section you will learn how to configure Smick and write your first sketch.
The Smick configuration (optional) is divided into 4 steps:
- Smick driver installation on PC: to run every time you connect Smick to a new PC;
- configuration of the serial terminal: to be executed every time you connect Smick on a different USB port of the PC;
- configuration of the Wi-Fi connection (ssid and pasword) on Smick: to be executed every time you connect Smick to a new Wi-Fi router;
- configuration of the MQTT broker on Smick: to be executed every time you connect Smick to a new MQTT broker.
In step 5 you will write, execute and memorize your first sketch.
1. Smick driver installation on PC

(2) The LED will indicate its status:
- Quick flashing indicates connection to Wi-Fi router
- Slow Flashing indicates connection to MQTT Broker
- Flash every 3 seconds indicates Execution mode
(3) Install the driver

- unzip it under the root of disk C: and run
C:\Smick\CH341SER\SETUP.EXE

5. Your first sketch
5. Your first sketch
Define the start command
] start=[led=!led #1]okand run it
] startok] The status LED starts to flash every second
You have created your first sketch!
If you wish to memorize it enter the command
] saveokIf you now turn off Smick (extract the USB cable from the PC) and turn it on again (insert the USB cable into the PC) your sketck will be executed automatically.
To understand the command created, stop it with
] stopokand try the following commands:
] led=1okthe LED lights up
] led=0okthe LED goes out
] led=!ledokthe LED lights up because:
- led was 0,
- ! is the negation operator then !led = !0 = 1
- therefore led = !led = !0 = 1
] led=!led #1okThe operator #1 repeats to infinity the command that precedes it once a second.
