  1. Running windows 10 and a TM4C1294 launchpad ethernet server with a tplink router inbetween the pc and the launchpad. When I try to test this with using putty telenet at 192.168.180.164 port 80 without typing anything, I get garbage characters like this : inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ inByte: ÿ Why is this occurring? I can stop it by screening for ascii characters with : if((inByte > 47) and (inByte < 123). #include <Energia.h> #in
  2. model of LaunchPad used - CC3200 LAUNCHXL name and version of the IDE : Energia E1.8.11E23 OS the IDE is running on : Windows 10 How to install the ethernet library in Energia for CC3200 LaunchXL Board? I have downloaded the library from energia github but it does not seem to work and gives error multiple libraries for Ethernet . The code is not compiling for Ethernet Board TM4C1294 which has the ethernet library installed. Could someone help me out with the proper installation of Ethernet Library? Thanks in Advance
  3. Hi all! I started a tcp server on my TM4C1294. At the beginning, my code works. Then I get new ip, dns, gateway and subnet mask from serial port. I want to restart my server with the new ip,dns,gw and subnet values. For this reason, I tried the below code... Unfortunately, the program stuck in "Ethernet.begin". Is there anything in order to restart the ethernet and tcp server with new ip? //LIBRARIES #include <stdint.h> #include <stdbool.h> //#include "inc/hw_memmap.h" //#include "driverlib/debug.h" #include <Ethernet.h> #include <Wire.h> //#i
  4. After sometime my "TM4C129EXL" card's ethernet server stops responding to clients. When i pause debugger in CCS, i found out that in "Tcp.c" file "tcp_slowtmr" function there is an infinity loop. Whole function => /** * Called every 500 ms and implements the retransmission timer and the timer that * removes PCBs that have been in TIME-WAIT for enough time. It also increments * various timers such as the inactivity timer in each PCB. * * Automatically called from tcp_tmr(). */ void tcp_slowtmr(void) { struct tcp_pcb *pcb, *prev; u16_t eff_wnd; u8_t pcb_remove; /* f
  5. Hi all, I'm just starting with the TM4C1294XL. I'm graduating from an Arduino mega that just doesn't have the speed I need in processing the Ethernet buffer. Can someone tell me how big the Ethernet receive buffer is when using energia? I've done calculations and I will be receiving about 3.2KB of information 10 to 20 times per second. This I have to process before the next batch is sent. So, I'm waiting for my new board to arrive, and I'm trying to do what I can to get ready. Thanks for any input. Jim

    MSP432E4

    I just spotted these and couldn't find any other thread about them. Headline is it an MSP432 with Ethernet, USB and CAN. http://www.ti.com/microcontrollers/simplelink-mcus/msp432/overview/msp432e4.html http://www.ti.com/product/msp432e401y http://www.ti.com/product/msp432e411y Launchpad: http://www.ti.com/tool/msp-exp432e401y
  7. Hi I am a newbie to MSP430 have coded on AVR and Arduino and trying out MSP for thr first time. Currently working on a project involving keypad, LCD, Ethernet. I have managed to find libraries of keypad and LCD and they seems to be working. But there is very few resources of ethernet and could not find anything. i have seen a post regarding W5200 but i unable to understand it, also RobG booster pack and library for W550 is great but i dont have the module and is out of stock. If anybody have any links on how to create the library for a newbie would be great and i

  9. Hello, I need help sending an Ethernet raw socket through my EK-TM4C1294XL (http://www.ti.com/tool/ek-tm4c1294xl). Here is what i have done so far: -> Using and modifing some NDK examples, but the problem is that i want a code in C/C++, not using a whole operating system (TI-RTOS SYS/BIOS); -> Including NDK libraries for use of it's functions and not installing the SYS/BIOS, however i am having lots of dependencies errors; -> Using Tiva C Series Ethernet examples, but they use the lwip TCP/IP protocol stack, i'm trying to send a raw Ethernet socket only; -> Using Energi
  10. Hi, As it seems to work on MSP430 device like MSP430F5529, I share it here too : http://forum.43oh.com/topic/9858-energia-library-wiznet-w5100w5200w5500/ Ethernet_Wiznet.zip
  11. Hi all, It was a real pain in the ass to find information about interfacing LP + Wiznet ethernet chip with energia so I'm here to share my work. I was looking for a library for ethernet chips from Wiznet (W5100,W5200,W5500) for TivaC series LP. The first problem I met was that as TM4C129 LP already has an ethernet.h library, I simply could not copy a new ethernet.h library for non-ethernet Ethernet_Wiznet.zip
  12. Hi, I am using the web client demo to send an HTTP GET request to a web server to read the data in json format. However the web server returns an error code 301 page moved error. How do I redirect my request to the new location? Does the ethernet library for TIVA support SSL HTTP GET requests?
  13. 0down votefavorite Hi, I am trying to implement Modbus TCP on TIVA 1294 using the following code. I am using a modbus slave simulator on a pc to check the following code. However, the code doesn't seem to be working. I have downloaded the code & the libraries fromhttp://myarduinoprojects.com/modbus.html. Please suggest me corrections if necessary. Also is there another working example available for modbus tcp/ip for ethernet on TIVA energia? Please guide. #include <SPI.h> #include <Ethernet.h> #include "MgsModbus.h" MgsModbus Mb; int inByte = 0; // incoming seri
  14. Hi , I have written a code for ethernet client using TM4c1294NCPDT launchpad and I am sending data to a server at api.pushingbox.com. The code sends data to the server after every 15 seconds, It works all the time, however sometimes suddenly the ethernet data transfer hangs, the microcontroller does not hang. Below is the void loop() I have used.Please help. void loop(){ kemasData(); //packing GET query with data Serial.println("connecting..."); if (client.connect(server, 80)) { sendData(); // koneksi = true; //connected = true u.count++; Serial.println(
  15. I am using TM4C129 LaunchPad for an Industrial IoT product. We want to have a web server running on it. I am looking into this example of setting up the IP address. To do it this way, every time you join a new network, you have to change the code for a different IP address. Is there a way to avoid this problem? Any example of how can I change the IP address automatically as soon as it joins a a new network? I believe that the TivaWare provided example enet_io for the TM4C129x board does what I am looking for. But I would like an example in Energia. Can you please help?
  16. It would be really awesome for my project if I could update code over Ethernet, instead of USB for my Tiva C connected. I've tried the latest version of the LM Flash Utility (Build 1613) and cannot seem to connect to the Tiva C over Ethernet with the utility. I have a MAC and IP set on my board using the Energia Ethernet UDP library and can verify them with a ping and look at my laptop's ARP table, but I am unsure if this is enough to satisfy the needs of the LM Flash Utility. I was hoping that the functionality would be supported "behind the scenes" in Energia, but that does not seem to be th
  17. Hi, I have a Mac desktop app that connects to a Connected Launchpad via USB serial. I decided to try to add ethernet port connection. I got tantalizing close but no cigar! I've been stuck on this for a week now so I need help. I had no problems adding the Ethernet.h library except for something very weird trying to do a conditional import. I have been using directives to compile for either the LaunchPad or the Connected LaunchPad: #ifdef PART_TM4C1294NCPDT // Connected LaunchPad #include "Ethernet.h" #elif defined( PART_LM4F120H5QR ) // LaunchPad #endif This seems to have bee
  18. WIZpix is an internet enabled RGB pixel controller with built in PoE. WIZpix uses W5500 internet appliance to connect to internet and MSP430F5172 MCU to control RGB pixels. Built-in DC/DC converter allows use of PoE, which eliminates need for directly connected power supply, ability to place controller far away from the outlet, and use of only one inexpensive CAT-5 cable. It
  19. hi all, I'm trying to use an Ethernet module that i bought called "Ethernet LAN Module for Arduino / microcontrollers with SPI (ENC26J80)". I found a few example for it for different MSP430's but i cant get it to work. Does anyone know how to make it work? witch pins to connect and example code would be great. thanks, Ofer.
  20. hello, I am working on project in which i need internet connectivity. I am using MSP430F5438A. I came across many ethernet controllers, but i chose ENC28J60. does anybody know how to interface ENC28J60 with MSP4305438A ? any help would be appreciated.
  21. This is a code library implementing a sockets-oriented interface to the WizNet W5200. It's been a long time coming, and the plan is to implement DHCP support soon; almost there, had to rewrite the lib from scratch to allow piecemeal I/O with various socket types first. For now, the code includes working examples for the MSP430G2553 and MSP430F5529 LaunchPads. It needs a lot of documentation work though so don't fret if you can't get them working :-) More to come... Link: https://github.com/spirilis/w5200sock After DHCP support is working on the older W5200, I am going to adap

  23. 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
  24. Hello, I am thinking on starting a new project, a web controlled robot!!! I was wondering if anyone has any experience with using an (Arduino)Ethernet shield with the MSP launchpad?? My plan is to build something like this: http://www.lynxmotion.net/viewtopic.php?f=20&t=6343 Or if anyone has any other ideas for easy, cheap web interaction with the launchpad. I don't want to use a wifi shield, because I would like to add video streaming in the future and wifi shields are not very video friendly. Thanks
  25. Ethernet - DMX Booster Pack. Uses WIZ820io on the Ethernet side and SN65HVD12 on the RS-485 side. XLR or RJ45 socket can be used. Compatible with MSP430, Stellaris, C2K, and Tiva LaunchPads. Will provide e1.31 example later on. If interested in a standalone version, I will have 2 and 4 universe versions very soon. 4 universe version will have Ethernet, XBee, and MIDI inputs.
