Here is an explanation of what every element and interface of the board does:
Ks0247 pinout.jpg


Specialized Functions of Some Pins

  • Serial communication: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data.
  • PWM (Pulse-Width Modulation): D3, D5, D6, D9, D10, D11
  • External Interrupts: D2 (interrupt 0) and D3 (interrupt 1).
  • SPI communication: D10 (SS), D11 (MOSI), D12 (MISO), D13 (SCK).
  • IIC communication: A4 (SDA); A5(SCL)


Detailed Use with ARDUINO Software as follows

Step1| Download the Arduino IDE

When you get the 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. ARDUINO has a powerful compatibility. 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.
thumb

Click“I Agree”to see the following interface.
thumb

Click “Next”. Pop up the interface below.
thumb

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.

Introduction for Arduino IDE Toolbar

Double-click the icon of Arduino software downloaded well, you will get the interface shown below.
Ks0313图片1.png
(Note: if the Arduino software loads in the wrong language, you can change it in the preferences dialog. See the environment page for details.)

Step2| Connect a USB to Serial Module

To program the Pro Mini board, you will need to connect an external USB to Serial module. Different USB to Serial modules might have different driver installation. In the following, we will introduce the use of pro mini with our keyestudio FTDI Basic Program Downloader.
See more details here.

Download the Driver Files

Driver file- KS0247.png
You can download the driver file from the link below:
https://drive.google.com/open?id=1vj4Is2LokXf3GDGcnumnAPmaI39uPhQk


Installing the Driver

The USB to serial port chip of this control board is FT232RL. So you need to install the driver for the chip. You can click the driver file here ft232r usb uart driver to download it.
In different systems, the driver installation is similar. Here we start to install the driver on the Win7 system.
Plug one end of your USB cable into the module and the other into a USB socket on your computer.

图片1-module.png

When you connect the module to your computer at the first time, right click your “Computer” —>for “Properties”—> click the “Device manager”, under Other devices, you should see the “USB Serial Port”.
KS0247- DRIVER 1.png

Then right-click on the device and select the top menu option (Update Driver Software...) shown as the figure below..
KS0247- DRIVER 2.png

Then it will be prompted to either “Search Automatically forupdated driversoftware” or “Browse my computer for driver software”. Shown as below. In this page, select “Browse my computer for driver software”.
KS0247- DRIVER 3.png

After that, select the option to browseand navigate to the “drivers” folder.
KS0247- DRIVER 4.png

Once the software has been installed, you will get a confirmation message. Installation completed, click “Close”.
KS0247- DRIVER 5.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.
KS0247- DRIVER 6.png


Step3| Hookup Guide

Driver installation completed, disconnect the module to computer, then connect it to pro mini board using F-F jumper wires. Shown below. The slide switch on the module is used to control the voltage for serial communication. Whether it is set to 5V or 3.3V, it can be programmed with the Pro Mini.

Connect well the module to pro mini board, then connect the pro mini board to your computer with a mini USB cable.


Step4| Select the Arduino Board

Open the Arduino IDE, you’ll need to click the “Tools”, then select the Board that corresponds to your Arduino.

Ks0247 board.png


Step5| Select your serial port

Select the serial device of the Arduino board from the Tools | Serial Port menu.
Note: to avoid errors, the COM Port should keep the same as the Ports shown on Device Manager.
KS0247- DRIVER 6.png

Ks0247 port.png


Step6| Upload the Code

Below is an example code 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!");
}
}


Ks0247 code.png

Then click verify button to check the errors. If compiling successfully, the message "Done compiling." will appear in the status bar.
KS0247 COMPILE.png

After that, click the “Upload” button to upload the code. If the upload is successful, the message "Done uploading." will appear in the status bar.
KS0247 upload.png



Step7| Open the Serial Monitor

After that, click the button to open the serial monitor.
Ks0247 monitor 1.png

Then set the baud rate to 9600, enter an “R” and click Send, that is, the computer will send the character R. When pro mini board receives it, you should see the D13 led flash once. "Hello World!" is sent to the computer, so that you should see the "Hello World!" is showed on the monitor.
