මේ තියෙන්නේ මම ලගදි හදපු Robot Arm එකක්. තාම හදලා නම් ඉවර කරලා නෑ. Design එකට මූලික අදහස ගත්තේ Dorna කියන robot arm එකෙන්. Stepper motors වලින් තමයි වැඩ කරන්නේ. (Nema17 මෝටර් 3 යි, 28BYJ-48 මෝටර් 2 යි) Firmware එක විදිහට grbl-5x සහ Development board එක විදිහට Arduino Mega 2560 + Ramps 1.4 පාවිච්චි කරලා තියෙනවා.<br />
<br />
<br />
ගොඩක් කොටස් හදලා තියෙන්නේ 3mm Cladding Boards වලින්. හැම කොටසක්ම වගේ කැපුවේ මගේ CNC Machine එකෙන්.<br />

The age before Micro controllers/ Microprocessors? I have just now completed a project that takes me into that time. <br /><br />This is an 8-bit Minimum Computer (Computation Machine) [1] that made from simple logic ICs, flip-flops and a few memory modules. It has a memory of 16 bytes and its maximum clock speed is not more than 5 Hz.<br /><br />The whole design is based on SAP-I Architecture and design was obtained from Ben Eater’s Youtube Channel [2]. Currently, it has 9 instructions (based on Intel 8080 instructions) and can be programmed it using machine language (That means programming from 1s and 0s)<br /><br />The project was started as a project for CO221: Digital Design Course, Department of Computer Engineering, University of Peradeniya.<br /><br />All the Printed Circuit boards were designed from the basics by us using Fritzing, fabricated by using the CNC, Builder_V3 and soldered and assembled by us. It took 2 months to complete the fabrications and another month for build motherboard (30x40cm) and debugging.<br /><br />After the evolution of the project, we hope to make it free and open source under Apache License 2.0</span><br />

Arduino එක්ක වැඩ කරන හැමෝම Transistors, Integrated circuits, Microcontroller, Microprocessor ගැන එහෙම අහලා ඇති. එ් වගේම Transistors එකතු වෙලා Integrated circuits හැදෙන හැටි වගේම IC එකතුවෙලා Microcontroller හැදෙන හැටිත් අහලා ඇති.<br />
<br />
නිකමට හිතලා බලන්න IC එකතු කරලා Microcontroller එකක්, හැදුවෙත් කොහොම තියෙයි ද ? පල්ලෙහා පිංතූරේ තියෙන්නේ අන්න ඒ වගේ පරිපථයක්. තවත් සරලව කිව්වොත් IC පාවිච්චි කරලා හදපු පොඩි Microcontroller එකක්.<br />
<br />
ඕනැම Microcontroller එකකට නිර්මිතියක් (Architecture) තියෙනවා. නිතරම ඇහෙන PIC, AVR, ARM වගේ නම් වලින් කියවෙන්නේ ඒ වගේ ජනප්රිය architectures කීපයක් තමයි.<br />
<br />
මේ නිර්මාණයට පාදක වුණේ SAP-I (Simple As Possible) කියන Architecture එක. මේක ගැන වැඩි විස්තර පොස්ට් එකේ අන්තිමට තියෙන ලින්ක් වලින් දැනගන්න පුළුවන්.<br />
<br />
ලොකුවට පෙනෙන පරිපථ පුවරුවේ තව පොඩි පොඩි මොඩියුල 11 ක් තියෙනවා. ඒවා ගැන හැදින්වීමක් ඉදිරි ලිපියකින් කරන්නම්. දැනට නම් විදිහට පමණක් ඉදිරිපත් කරන්නම්.<br />
<div>
<br />
<ul>
<li>Clock Module</li>
<li>Program Counter</li>
<li>Registers (RegA, RegB, Instruction Register, Memory Address Register)</li>
<li>ALU (Arithmetic and Logic Unit)</li>
<li>Output Module (4 digit 7 Segment display)</li>
<li>RAM</li>
<li>Programmer </li>
<li>Control Sequencer (Control Unit)</li>
</ul>
<br />
මේක නිර්මාණය කරන්න IC 46 ක් පාවිච්චි කරලා තියෙනවා. ඒ වගේම Indicators විදිහට LED Bulbs 76කුත් පාවිච්චි කරලා තියෙනවා.<br />
<div>
<br />
<ul>
<li>39 x 7400 Series ICs</li>
<li>4 x 555 IC</li>
<li>3 x AT28C16 EEPROM </li>
<li>76 x LED </li>
</ul>
<div>
<br /></div>
Circuit Design කරන්නයි, PCB ටික Fabricate කරන්නයි මාස දෙකක් විතර මහන්සි වෙන්න වුණා. ඒ ටික ඉවර වෙලා මේක වැඩකරන තත්වෙකට ගන්න තව මාසයක් විතර මහන්සි වුණා.<br />
<br />
මේකේ Performance ගැන කිව්වොත්,<br />
<br />
Data Bus<br />
>> 8-bit Bus Architecture<br />
<br />
Clock Speed<br />
>> min 1Hz, max 5Hz<br />
<br />
Memory<br />
>> RAM : 16 bytes (16x8 bits)<br />
>> Storage: 2 bytes (Register A, B)<br />
<br />
Arithmetic Unit<br />
>> Addition, Subtraction only<br />
<div>
<br />
ඇත්තටම මේ අගයයන් සංසන්දනය කලාම Arduino Uno Board එකේ තියෙන “Atmega328” AVR IC එක මේක වගේ x16,000,000 ගුණයක් වේගවත්. Memory එක (Flash Memory) x2,000,000 ගුණයක් විතර වෙනවා.<br />
<br />
<br />
<b>Atmega328</b><br />
> Clock Speed ----- 16 MHz<br />
> Flash Memory --- 32 KB<br />
> SRAM -------------- 2 KB<br />
> EEPROM --------- 1 KB<br />
<br />
හැබැයි Digital Logic Design, Computer Architecture, Microcontrollers ගැන ඉගෙනගන්න කැමති කෙනෙක්ට නම් මේ වගේ දෙයක් හදලා ගන්න Experience එක සෑහෙන වටිනවා.<br />
<br />
මේක වැඩකරන විදිහ , Machine Language එකෙන් Programming කරන විදිහ ගැන වෙලාව ලැබෙන විදිහට කියාදෙන්න බලන්නම්. Eater.net කියන site එකේ සහ Ben Eater' Youtube Channel එකෙනුත් මේ ගැන හොද පැහැදිලි විස්තර හොයාගන්න පුළුවන්.<br />
<br />
මේ Project එක කලේ පේරාදෙණිය ඉංජිනේරු පීඨයේ Computer Engineering Project (2nd Year) එකක් විදිහට. මේ වගේ නිර්මාණයක් කරන්න මුලින්ම අදහසක් දුන්න Dr. Kamalanath Samarakoon සර්ටත්, නිර්මාණ කටයුතු සදහා උදව් කරපු Digital Design Lab එකේ Instructors ලා හැමෝටමත්, මගේ Project Team එකේ හැමොටමත් ස්තූතිවන්ත වෙනවා.<b style="font-weight: normal;"><br /></b>

Logic Gates එක්ක වැඩ කරලා තියෙන කෙනෙක් නම් 74 Serial එකේ IC ගැන නොදැන ඉන්න විදිහක් නෑ. AND, OR, NOT වගේ මූලික තාර්කික ද්වාර වල ඉදලා Counters, Multiplexers, Registers වගේ පුළුල් පරාසයක IC වර්ග 74 serious එකේ අන්තර්ගත වෙනවා.</div>

මේවත් එක්ක වැඩ කරන ගොඩක් අයට තියෙන ප්රශ්නයක් තමයි මේ IC වලට අදාල datasheet හොයාගන්න එක. ඒ ප්රශ්නෙට පොඩි විසදුමක් විදිහට තමයි මම මේ Android app එක නිර්මාණය කලේ. දැනට සුලබව පාවිච්චි වෙන 74 series එකේ IC 150+ කට අධික ප්රමාණයක pinout diagrams වගේම ඒවායේ datasheets download කරගන්න direct links මේ ඇප් එකේ අන්තර්ගත වෙනවා. </div>

මේ පිංතූරේ බැලුවම විහිළුවක් වගේ පෙනෙයි. හැබැයි අපිට හරි දැක්මක් යටතේ එකතු වෙලා වැඩ කලොත් අපේ රට, ශ්රී ලංකාව, වකන්ඩාවක් කරන එක අමාරු දෙයක් නෙවෙයි.<br />
<br />
අපේ මුතුන්මිත්තන් මුහුදු වගේ වැව් නිර්මාණය කලෙත්, පුරාතන ලෝකයේ ගීසා පිරමීඩ වලට පමණක් දෙවෙනි වෙන මහා චෛත්ය හැදුවෙත් අපේම දැනුම හා තාක්ෂණයෙන්. (තවමත් ජනප්රවාදයක් විදිහට තිබුණත්, රාවණාගේ ලංකාපුර රාජධානිය ගැනත් එහි පැවති තාක්ෂණය ගැනත් අමතක කරන්න බෑ.)<br />
<br />
හැබැයි හැමදාම කලා වගේ අතීතය ගැන උදම් ඇනීම නතර කරලා, අද දවසත් අනාගතයත් රටේ දියුණුව වෙනුවෙන් කැප කරන්න පුළුවන් නම් වකන්ඩාවක් ගොඩනැගීම අපහසු ඉලක්කයක් නෙවෙයි.<br />

<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6ZqSWS_-U5sDjHgtckaMvahgaG8psO3ZOGpRukkaavydR-4X9TYA9ihyphenhypheniuXcWOfUlGLEDDVm8wlvc7nIni5ZKALpJVYEPq7iJIQKw8me8pU6WiboPyi4HkQQ66gwrnAhRgPur59fVmi8/s1600/300px-STM32_Blue_Pill_perspective.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="195" data-original-width="300" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6ZqSWS_-U5sDjHgtckaMvahgaG8psO3ZOGpRukkaavydR-4X9TYA9ihyphenhypheniuXcWOfUlGLEDDVm8wlvc7nIni5ZKALpJVYEPq7iJIQKw8me8pU6WiboPyi4HkQQ66gwrnAhRgPur59fVmi8/s1600/300px-STM32_Blue_Pill_perspective.jpg" /></a></div>
<br />
Usually, we need a <b>USB to TTL programmer</b> (AKA Serial Programmer) or <b>STLink </b>programmer to program STM32 based boards.<br />
<br />
But you can direct program <b>STM32F103CB Blue Pill Board</b> (As shown in above picture) through its built-in micro USB port using a custom bootloader.<br />
<br />
<br />
1. Connect the hardware as below. You can use any USB to TTL Converter.<br />
<br />
<b><span style="white-space: pre;"> </span>Programmer Device</b><br />
<span style="white-space: pre;"> </span>Tx ----------------> A10<br />
<span style="white-space: pre;"> </span>Rx ----------------> A09<br />
<span style="white-space: pre;"> </span>5V ----------------> 5V<br />
<span style="white-space: pre;"> </span>Gnd --------------> GND<br />
<br />
<br />

<br />
<br />
<br />
6. After the success message, power off the board and set <b>BOOT0</b> pin to '<b>0 position'</b> again.<br />
<br />
7. Connect USB Mini cable.<br />
<div>
<br /></div>
<div>
8. Open the Arduino IDE and select the board STM32F103C (Watch this video to know how to install STM32 Package: <a href="https://www.youtube.com/watch?v=K-jYSysmw9w">https://www.youtube.com/watch?v=K-jYSysmw9w</a>)</div>

<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<h3 style="clear: both; text-align: left;">
<span style="color: red;">Note</span></h3>
<div class="separator" style="clear: both; text-align: left;">
If you unable to find this special port, you need to install <b>Maple Mini Drivers</b>. For that, please go to <i>Arduino install directory</i>. (Mine is <i>C:\Program Files (x86)\Arduino</i>)</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Arduino install directory > hardware > Arduino_STM32 > drivers > win</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
(Example: <i>C:\Program Files (x86)\Arduino\hardware\Arduino_STM32\drivers\win</i>)</div>
<div class="separator" style="clear: both; text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: left;">
Then run the file named, <b>install_drivers.bat</b></div>
<div class="separator" style="clear: both; text-align: left;">
<b><br /></b></div>
<div class="separator" style="clear: both; text-align: left;">
<b><br /></b></div>
<div class="separator" style="clear: both; text-align: left;">
11. Now you can upload a sketch to the board and get a fun :-) </div>
