Lightweight web server using the MSP430


Need a tiny web server? [Rob] over on the 43oh forums made an Ethernet booster pack for the very popular TI MSP430 microcontroller. If that’s not enough, [Rob] also put together an all-in-one solution with a MSP430 and Ethernet controller that can be powered by a battery. Along with the web server that fits in just 5k of flash, we’re going to say [Rob] has a very good solution for remote sensing and data logging.
For his Ethernet-enabled 430, [Rob] chose to use the WIZnet W5200 Ethernet controller. This chip communicates with the 430 via and SPI interface and has a hardware TCP/IP stack that supports TCP, UDP, and PPPoE, offloading all the low-level stuff off of the 430 and onto the Ethernet controller.
After the break there are a pair of videos of [Rob] showing off his tiny web server. A few neat features include a full memory dump of the 430, as well as a reading the states of all the pins via an HTML page. If you’re looking for a way to collect data over Ethernet, we don’t think you could do better than [Rob]‘s tiny 430-based web server. Also, if you’d like to control a few devices over the Internet, [Rob] included a few optoisolators for lights or appliances.
The code is available on the 43oh forum page, but [Rob] says he’ll clean that up and put it in a Git.

DARwIn-OP Humanoid Robot & Basic Bioloid Robot Training [Samarinda Seberang, 5-6 Juni 2012]

     Pada tanggal 5-6 Juni 2012, Innovative Electronics melalui Divisi Training menyelenggarakan "DARwIn-OP Humanoid Robot & Basic Bioloid Robot Training" di Samarinda Seberang. Training kali ini diikuti oleh 10 orang peserta.

Peserta training beserta instruktur
         
     Training kali ini secara ekslusif membahas robot humanoid DARwIn-OP. Ya, robot humanoid yang satu ini memang cukup menarik untuk dipelajari, selain fitur-fitur handal yang ditawarkan (sebanding dengan harganya), robot ini juga telah memiliki nama yang cukup populer di ajang RoboCup (event tahunan kompetisi humanoid robo soccer international), tentunya bukan hal yang aneh jika setiap orang cukup penasaran untuk "bermain" dengan robot humanoid ini. Robot humanoid ini telah dilengkapi dengan embedded PC (dual core), aktuator Dynamixel MX series dari Robotis, dan kamera 2 MP HD. Spesifikasi lebih lengkap mengenai robot humaoid ini terdapat pada link berikut ini [DARwIn-OP]
     Training ini terbagi menjadi 2 hari. Hari pertama membahas perihal overview DARwIn-OP, basic operational, dan sedikit proses development untuk DARwIn-OP. Hari kedua dilanjutkan lagi proses development yang lebih menekankan ke desain motion (gerakan) menggunakan action editor serta pemrograman dengan bahasa C++. Hari kedua juga membahas perihal troubleshooting untuk kasus-kasus yang umum dijumpai. Proses development DARwIn-OP terselesaikan pada tengah hari kedua. Sisa waktu tengah hari diisi dengan basic training untuk Bioloid Robot (predecessor DARwIn-OP).

Development DARwIn-OP pada posisi standing
     Peserta cukup antusias mengikuti setiap tahapan training walaupun robot humanoid ini cukup baru bagi peserta. Proses development DARwIn-OP yang berbasis full command line (tanpa GUI) tidak menyurutkan antusias peserta untuk berkreasi. Akhirnya, antusias dan kerja keras peserta terbayar lunas setelah berhasil memprogram dan mendesain gerakan untuk DARwIn-OP maupun Bioloid Robot.
             
Peserta sedang sibuk "bermain" dengan robot

Hasil kreasi peserta dengan DARwIn-OP terdapat pada video berikut ini:


DARwIn-OP Dance from Support Team 2 IE on Vimeo.

     Robot humanoid DARwIn-OP ini dapat digunakan untuk ikut serta pada ajang Kontes Robot Seni Indonesia maupun Kontes Robo Soccer yang setiap tahun diadakan di Indonesia. Robot humanoid ini dapat di-explore dan dikembangkan lebih lanjut untuk berbagai riset dan aplikasi.      

Selamat berkarya dan berinovasi !

WIZnet Serial to Ethernet Gateway with PIC Microcontroller

By Idris Zainal Abidin

This is article from one of electronics amateur, experience in embedded design and programming. He has utilize the BPS-5-3 breadboard power stick, LC04A Logic Level Shifter and WIZnet Serial to Ethernet Gateway, to show the basic interface between WIZnet gateway, Graphic LCD, PIC microcontroller and the setup.



Main Components:

1. WIZnet Serial-to Ethernet Gateway.

2. PIC16F688 Microcontroller.

3. Breadboard GL-12 (C&D).

4. Breadboard Power Stick 5V 3V3.

5. Logic Converter 4 Channels.

6. 5110 Nokia LCD.

clip_image002

Software Required:

1. MPLAB X IDE V1.20

2. MPLAB XC8 Compiler

*PIC source code is provided, you can download in under attachment at bottom of this article.

Schematic Diagram:

clip_image004

From the schematic diagram,

  • PIC and WIZnet module needs 5V
  • 5110 Nokia LCD needs 3.3V
  • Logic Converter needs 5V and 3.3V

By using the Cytron’s Breadboard Power Stick 5V 3V3, I have save my time and the breadboard space. J

This module provides the DB9 connector/RS232 communication, so you need the MAX232 chip to communicate. I don’t want to use it (MAX232) because I don’t have it. At the underside of this module, there have J2, J3, J4 and J5. Those pins represent 5V (J2), GND (J3), TX (J4) and RX (J5). We can use it but we need a logic converter because the TX and RX pins are low voltage TTL (3.3V) and Cytron’s Logic Converter 4 Channels is really helpful. J

Setup WIZnet Serial-to-Ethernet Gateway using Configuration Tools Software:

You can find the download link here: http://www.cytron.com.my/viewProduct.php?pcode=WIZ110SR&name=WIZnet%20Serial-to-Ethernet%20Gateway

clip_image010

  • Launch the WIZ1x0SR_105SR_CFG_V3_0_2.exe and connect the WIZnet module using LAN cable and don’t forget the 5V supply.
  • Click ‘Search’. It should find your device and you will be able to configure its IP address, port, and whether you want to use TCP or UDP.

clip_image012

clip_image014

  • In Network tab, set your ‘Local IP’, ‘Subnet’, ‘Gateway’ and ‘Server IP’ include the ‘Port’ number. Uncheck the ‘Use UDP mode’ because we want to use the TCP/IP mode.
  • In Serial tab, set the baudrate ‘Speed’, ‘DataBit’, ‘Parity’, ‘Stop Bit’ and ‘Flow’ as shown in the figure below.

clip_image016

  • In Option tab, just follow the setting below. There have ‘Data Packing Condition’ that you can play with, but for now just make it simple setting.

clip_image018

  • After you have done all the settings, click ‘Setting’ to complete the WIZnet module configurations.

clip_image020

clip_image022

  • Ok, you have done the setting for your WIZnet module. Now you need to set your PC. Open ‘Internet Protocol’ and set the ‘IP address’, ‘Subnet mask’ and ‘Default gateway’ as follow – Click OK.
  • Open HyperTerminal and write connection ‘Name’ – Click OK.
  • Choose ‘Connect using’ TCP/IP (Winsock), then set ‘Host address’ and ‘Port number’ – Click OK.

clip_image024clip_image026

A. This is the flow of firmware programming. Once the board is powered up, LCD will display the Welcome note. It will wait until the SW (input RA4) is pressed.

clip_image028

B. After SW is pressed, data is transferred from PIC to PC through WIZnet module using TCP/IP protocol. HyperTerminal displays all the data receive. In LCD site, it displays ‘Receive:’ as shown below.

clip_image030clip_image032

C. You can write any characters and it will transfer the data to WIZnet – PIC. Once receive, LCD will displays the data.

That’s all. Thank you :)
