  1. Wonderful! You seemed to implement web server and parser? When I saw your above post, you must have used old LauchPad using MSP2553, not MSP430F5529. I have suffered by its too small memory size. But, you looks implemented driver of W5500 and LCD, and code for web server and HTML parser on 4Kbyte flash and 0.5Kbyte Ram. It's really awesome. Can I ask you how many bytes its code size is? Thank you.
  2. I recommend you use new Launchpad and WIZ550io. With them and new Energia IDE, you can develop your code like doing it using Arduino. Please refer to my post, http://forum.43oh.com/topic/4154-energia-library-ethernet-using-wiz820io/ Thank you.
  3. Hi All, If you visit https://github.com/Wiznet/Energia_Library_WIZnet, then you can see how to setup the development environment of new launch pad and WIZ550io. Enjoy all examples! Thank you.
  4. Hi RobG, Did you make W5500 BP? Wonderful! I think my energia library will run on your W5500 BP if you match SPI signals correctly. In order to use W5500 instead of WIZ550io, you have to change one option in W5100.h of ethernet library from WIZnet make this sentense, " #define WIZ550io_WITH_MACADDRESS // Use assigned MAC address of WIZ550io " comment. It' All what you have to do, I think. Thank you,
  5. @@abecedarian Arduino Ethernet library doesn't use interrupt mode and it operates in only polling mode, so we don't need nINT signal. And, after internal initialization of WIZ550io, RDY signal will become HIGH. You can connect RDY pin to one of launchpad GPIOs and monitor whether its value become HIGH. And you can just wait for a while, at most 100ms, after booting without checking RDY pin. To monitor RDY pin is up to you. :grin: And RST signal is the same. As you know, when you press RST button, RST signal asserted to LOW. If you connect RST pin of LP to nRESET of WIZ550io, then
  6. Hi, To test ethernet connectivity, I prepared two boards, MSP-EXP430F5529LP and WIZnet's WIZ550io. I'm convinced that you already know MSP-EXP430F5529LP. For WIZ550io, refer to http://wizwiki.net/wiki/doku.php?id=products:wiz550io:allpages This is a module which supports TCP/IP functions and has ethernet RJ45 jack. It provides SPI bus for interface with host MCU. Arduino ethernet examples are working on the platform using WIZnet's products, so we can run all examples from arduino with this module.

  7. Hi All, Frankly speaking, I couldn't find the solution out to solve the lack of memory. But TI announced new launchpad having bigger MCU, MSP430F5529, which consists of 128KB Flash and 8KB RAM. I ordered it online and got it last week. I downloaded new energia IDE from www.energia.nu I updated the new energia IDE(energia-0101E0010-windows) to support TCP/IP connectivity. Finally, I got all examples from arduino run successfully. Now, I'll post what I did step by step from next post Thank you. javakys
  8. Hi All, I updated examples for Ethernet library. As Many examples didn't work well because of the lack of RAM on MSP430. So, I eliminated many examples from github, only two examples, "charServer" and "UDPSendReceiveString", remain with small update. What I updated is making majority of Serial.print() sentences be comment. Frankly speaking, when I test Ethernet library on Arduino platform, I felt SRAM inside ATmega328 is too small though it is 2K Bytes. MSP430 has only 0.5K bytes SRAM at most(in case of 2553), It makes many examples working well on Arduino be hangup during executio
  9. Hi All, I registered new Energia including Ethernet Library and examples on Github. Please refer to https://github.com/javakys/Energia_Ethernet_Library_Included.git Enjoy it. Thank you.
  10. Hi All, I use MSP-EXP430G2 ver 1.5 with M430G2553. As for pin description of WIZ820io, refer to http://www.wiznet.co.kr/sub_modules/en/product/Product_Detail.asp?cate1=5&cate2=42&cate3=0&pid=1161#tab This is pin map between MSP-EXP430G2 and WIZ820io. MSP Launch pad WIZ820io ============================== J1 VCC <--------------> VCC J1 P1.5 <--------------> SCLK J1 P2.0 <--------------> nSS J2 GND <--------------> GND J2 RST <--------------> nRE
  11. Hi All, I added ethernet library to Energia. Though Arduino library supports ethernet function, Energia doesn't provide any library for ethernet yet. So, I tried to add ethernet library for arduino onto Energia IDE. Finally, I did it and examples of ethernet library for arduino work well. But as MSP4302553 has less SRAM memory than arduino Uno, you have to make some serial.print() sentence as comment. Anyway, if anybody want to update this ethernet library, feel free do that. As .zip file is too big, I'll post it on Github and share to all of you as soon as possible. T
