Projects



Arduino 2560 Burn Test Program


Connect PLUS main control board to computer with USB cable. Taking Keyestudio LOGO as a reference, toggle the switch to the left for on and right for off.

The positions of the 16-pin DIP switch and the 6-pin DIP switch are shown below:

Click 5014click1.png to upload the program to PLUS main control board, and wait for a prompt of successful uploading in the lower left corner.

Then click 5014click2.png to open the watch window and set baud rate at 115200; send sequentially:

a: lighting test (D13)
b: memory test
c: pin test

ESP8266 Burn Test Program


Connect PLUS main control board to computer with USB cable. Taking Keyestudio LOGO as a reference, toggle the switch to the left for on and right for off.

The positions of the 16-pin DIP switch and the 6-pin DIP switch (toggle to serial port 1) are shown below:

Choose the development board "Generic ESP8266 Module" and port.

U)ES(~LHV6GKMDCE8CS~U5T2222222.png

Click 5014click1.png to upload the program to PLUS main control board, and wait for a prompt of successful uploading in the lower left corner.
If the upload fails, unplug the USB cable and reconnect it before uploading.

NOTE: Before each programming of esp8266, the switch must be toggled at GND-GPIO0, and it can be used as a normal IO port if turn it off after programming.

TEST_MEGA-ESP Remote Control

Upload the project on Chapter 7.2, and choose the development board when uploading.

Upload code "TEST_MEGA-ESP.ino" to the main control board and choose the development board "Arduino Mega or Mega 2560".

After successful uploading. Toggle the switch to the position shown below:

5014pinpositions4.jpg

Open Hotpot and connect ESP8266 to WIFI network.

And open the serial port after successful connecting, IP address will be displayed.

Open this address of 8266 on any browser, the [ON] [OFF] of LED state will control the onboard LED on 2560 and ESP8266.
