Keyestudio Main Board With Pin Header Interface


Introduction

keyestudio main board with pin headers has the same basic functions as [1]. It is a microcontroller board based on the ATMEGA328P-AU, which has the same function as ATMEGA328P(-PU), fully compatible with ARDUINO UNO.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, 2 ICSP headers, and a reset button.
It breaks out all the digital and analog pins in the form of 3PIN headers (G, V, S).
S pins correspond to all 14 digital pins, 6 analog pins. G pins for ground. V pins for VCC. You can control the voltage of VCC via a slide switch for 5V or 3.3V.
When switched to 5V, level on serial communication port is 5V, voltage of pins is 5V. When switched to 3.3V, level on serial communication port is 3.3V, voltage of pins is 3.3V.
It also breaks out two 4PIN headers for serial communication and IIC communication. So it is more easier to connect external sensors and modules.
As for keyestudio main board, its voltage-regulator chip is NSP1117. When connect external power, output 5V, drive current is 1A.
But for this keyestudio main board with headers, its voltage-regulator chip is MP2307DN. When connect external power, output 5V, drive current is 2A.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

the reference for the Arduino language;

Detailed Test with ARDUINO Software as follows:

Step1 | Download the Arduino environment (IDE)

When you get the main board, first you should install the Arduino software and driver.
We usually use the Windows software Arduino 1.5.6 version. You can download it from the link below:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x
Or you can browse the ARDUINO website to download the latest version from this link, https://www.arduino.cc, pop up the following interface.
KS0313-1.png

Then click the SOFTWARE on the browse bar, you will have two options ONLINE TOOLS and DOWNLOADS.
KS0313-2.png

Click DOWNLOADS, it will appear the latest software version of ARDUINO 1.8.5 shown as below.
KS0313-3.png

In this software page, on the right side you can see the version of development software for different operating systems. You should download the software that is compatible with the operating system of your computer.
We will take WINDOWS system as an example here. There are also two options under Windows system, one is installed version, the other is non-installed version. For simple installed version, first click Windows Installer, you will get the following page.

KS0313-4.png

KS0313-5.png

This way you just need to click JUST DOWNLOAD, then click the downloaded file to install it.
For non-installed version, first click Windows ZIP file, you will also get the pop-up interface as the above figure.
Click JUST DOWNLOAD, and when the ZIP file is downloaded well to your computer, you can directly unzip the file and click the icon of ARDUINO software to start it.


Installing Arduino (Windows)

Install Arduino with the exe. Installation package downloaded well.

You can press Browse… to choose an installation path or directly type in the directory you want.
Then click “Install” to initiate installation.
thumb

Wait for the installing process, if appear the interface of Window Security, just continue to click Install to finish the installation.

Installing Driver

Next, we will introduce the driver installation of main board. The driver installation may have slight differences in different computer systems. So in the following let’s move on to the driver installation in the WIN 7 system.
The Arduino folder contains both the Arduino program itself and the drivers that allow the Arduino to be connected to your computer by a USB cable. Before we launch the Arduino software, you are going to install the USB drivers.

KS0001-1.jpg

Plug one end of your USB cable into the Arduino and the other into a USB socket on your computer. When you connect main control board to your computer at the first time, right click the icon of your “Computer” —>for “Properties”—> click the “Device manager”, under “Other Devices”, you should see an icon for “Unknown device” with a little yellow warning triangle next to it. This is your Arduino.

Driver 1.png
Then right-click on the device and select the top menu option (Update Driver Software...) shown as the figure below..
Driver 2.png

It will then be prompted to either “Search Automatically for updated driversoftware” or “Browse my computer for driver software”. Shown as below. In this page, select “Browse my computer for driver software”.
Driver 3.png

After that, select the option to browseand navigate to the “drivers” folder of Arduino installation.
Driver 4.png

Click “Next” and you may get a security warning, if so, allow the software to be installed. Shown as below.
Driver 5.png

Once the software has been installed, you will get a confirmation message. Installation completed, click “Close”.
Driver 6.png

Up to now, the driver is installed well. Then you can right click “Computer” —>“Properties”—>“Device manager”, you should see the device as the figure shown below.

Step4| Select the Serial Port

Select the serial device of the Arduino board from the Tools | Serial Port menu. This is likely to be COM3 or higher (COM1and COM2 are usually reserved for hardware serial ports). To find out, you can disconnect your Arduino board and re-open the menu; the entry that disappears should be the Arduino board. Reconnect the board and select that serial port.

Note: to avoid errors, the COM Port should keep the same as the Ports shown on Device Manager.

Step5| Upload the Program

Below is an example program for displaying the Hello World! Copy and paste the code to the Arduino environment IDE.

int val; 
int ledpin=13; 
void setup()
{
Serial.begin(9600); 
pinMode(ledpin,OUTPUT);
}
void loop()
{
val=Serial.read();
if(val=='R')
{
digitalWrite(ledpin,HIGH);
delay(500);
digitalWrite(ledpin,LOW);
delay(500);
Serial.println("Hello World!");
}
}

Then click verify button to check the errors. If compiling successfully, the message "Done compiling." will appear in the status bar.
