Wifi communication with microcontroller

[maestro63]

Hi, I'm doing a project to send messages from a PC to a micro controller using WiFi. The MCU will intern display the message on an LCD. I have doubts about what devices I should buy to make the wifi communication and also what type of MCU I need to buy?...Any suggestions...

What are the devices found so far and why do you doubt them?

I have done some research but haven't found any devices so far and I needed suggestions on which MCU comes with wireless module or do I need to buy the wireless module separately??...I only need to send a maximum of 32 characters message since the LCD is 2 by 16.

actually I found out I can use Black Widow which is an "Arduino Duemilanove compatible clone but it has some components switched out for surface mount equivalents to free up space for the wireless module" http://www.seeedstudio.com/depot/blackwidow-10-p-613.html?cPath=79_82...I am not sure which components have been switched..

Also found out on MRF24WB0MA wireless module which is connected to PIC microcontrollers via a 4-wire SPI interface...so which option should be sufficient and less complicated to implement my project??...thanks

I think it will be difficult for anyone here to judge which will be sufficient as we don't know the requirements of the project. For example, is there a range, power, size, price, or latency requirement (to name a few)?

I guess my first suggestion would be to avoid wireless links. Especially if you want to keep the project simple.

And if it absolutely must be wireless, go with whatever product comes with the best support and documentation because you're definitely going to need it. Wireless links, and their drivers, have a way of breaking in ways you wouldn't expect.
