Project with an 430 Launchpad + wifi?


Recommended Posts

Hello everyone!!

 

I'm a 21 years old engineer student from Spain, and I need your help, because I'm going to do a really big proyect (for me)!

 

I need to control a microcontroller from my android smartphone. I think that the 430 Launchpad with a wifi module would be adecuate.

I worked with a PIC couple years ago, and i don't know a lot about TI microcontrollers, but they are really cheap, and I need a cheapest project.

 

What wifi module would you recomend for me?

 

I'm searching for, but I can't find much.

I read on the wiki that CC3000 is a plug-in wifi

what do yoy think about this:

 

http://es.mouser.com...researchtiwiSL/

 

or this (I think this si the perfect one):

 

http://es.mouser.com...cc3000tiwislem/

 

Do you think they would be compatible (pin conectors)?

 

they are both designed to fit into this http://www.ti.com/tool/msp-exp430fr5739

 

also doing tcpip requires abit of ram and flash space which you probably would have a hard time fitting into one of the value line chips, but since this other chip is also a 430 most the code should work on it.

 

if your willing to spend that much for a module, another dev board couldnt hurt right? :P

 

i think mouser is offering a free fram for dummies book too

 

take a look at some specs http://www.ti.com/product/msp430fr5739

Those are both the same product, one is listed through TI, and the other through LS Research. They also have the module without the boosterpack breakout for half the price.

 

The module needs 6kb code space, and 3kb ram minimum on the host msp430, as per TI http://www.ti.com/tool/cc3000tiwislem

The module takes care of all the tcp-ip and wifi stuff, so you don't have to code that.

 

There are other options. Complete wifi to serial modules can be found on ebay (30 to 40 usd). There is 10 dollar or so ethernet to serial adaptors as well. You could connect the msp430 thru ethernet to your wireless router, and connect via wifi that way.

 

Or you can use a linux based wireless router, and hack it to add a server and serial to msp430.

Really thanks for the answers!

my fault! I got confused between the LaunchPad and de Experimenter Board! thanks for solving my doubt.

Ok! i'm going to check the diferents MSP430s, and i'll choose the best in order to work with the CC3000 wifi chip.

 

new things:

 

1) yesterday i found http://www.ti.com/tool/cc3000em that is (I think) a full compatible module for the Launchpad. It says "Available for backorder"... is this that it'll be on the shop next month?? next year??

 

2) Is it preferable to use the serial port (and a serial to wifi module) or the module I tell you on the point one?

 

Thaks everybody, i'm getting a lot of knowledge with you.

to Answer 2)

How much work do you want to put into this project? serial to wifi module makes things super easy and fast to get up and running

If you use just a straight wifi module, you will have to implement a 802.11 stack, tcpip and possibly dhcp....which seems like a lot of work if you don't have experience in working with them

 

Just my opinion....

The module they linked to has most of that built in, but a serial to wifi module would be mostly transparent to a mcu, almost drop in.

Microchip has the Wifi module (RN-171) that just needs a serial port to talk to Wifi. It can be set as an AP so that smart phone can connect to without an AP. The TI module needs an AP to work with.

 

The TiWiSL module is only $25 at DigiKey, and you can just connect couple wires to make it work with your MSP430 FRAM board. I made a small breakout board for this TIwi module. If you need the Eagle file I can upload here.

At $25, it is cheaper than Wiznet's $30 solution. your part could help us make a BoosterPack. As usual.. anyone who takes this up gets $10 for the first batch of boards from Seeed.

Any chip that can work with the launchpad board and is capable of running the firmware for the CC3000? I was under impression that it works with the FRAM board and the Stelarris. Oh yeah, it should be trivial to make it work with the Stelaris launchpad. The part I mentioned was this one:
