Introduction: Smart, Nice and Coolmay HMI for Arduino
This is the latest mini-touchscreen I bought to control an Arduino board under Modbus TCP communication.
Step 1: Some Technical Skills About the MT6037H-W
This touchscreen is very small (3.5'') and so functional. I bought it on a chinese website for about 100 euros. The basic skills:
-a LAN to communicate with the ethernet shield directly
-an USB1 link with a special USB wire to power up the WAN I think (not for download)
-a WAN to download the Coolmay sketch
-a free software
-MODBUS TCP communication and other ways
Step 2: First Install, Driver and Wire Links and Various Usefull Source Codes
The wiring is very easy and I give a tutorial where you can find:
-the software install
-the driver install
-the settings of the Coolmay IP address for sketch download (something like 18.104.22.168)
-the IP address settings for communicate with the ethernet shield with Modbus TCP (something like 192.168.0.85) and use the sketch IPsearch.OP6
-an example of dashboard and the sketch ESSAImodbus.OP6
-the arduino sketch
I supply: the arduino sketch (Light.rar), IPsearch and ESSAImodbus sketch (ESSAImodbus.rar), mudbus tcp library (Mudbus.rar), Coolmay software (CoolMayHMIEN.rar).
Step 3: Conclusion
I don't have test all the functions of this smart, small and cheap display.
It suits to control and to monitor tiny systems. It's a very valuable choice compared with MAGELIS STU display from Schneider (very very expensive) and its sofware also expensive.
Thanks to all interesting tutorial.
