I am looking for suggestions on which PIC MCU to use with MRF24WB0MA (wifi transceiver module which is compatible with PC18/24/32 and dsPIC)....I want to send messages (80 chars) from my PC to this MCU through wifi and display it on a 20 by 4 LCD. I plan to make my whole module to be battery powered and I found out that the PIC18F1220 supports this requirement. The problem comes in connecting the wifi module to WLAN and which TCP/IP protocols to use in order to establish a successful transfer of information from the PC to the PIC MCU?....Thanks --------------------------------------- Posted through http://www.EmbeddedRelated.com

Anyway, that's what we are doing.

For the microchip TCPIP stack at least 128kb rom and 64kb ram are required I think. You'd be best of with a pic32, but it's a totally new architecture. Then on how to exchange data: you have many options. There are a number of way to use custom sockets with Microchip TCPIP stack, but I can't give you any advice as I haven't personally used any.

Yet another undocumented wifi part. "Works with the free tcp stack", great. If I need something which "works with", I'd go for a readily available TV-set, phone, notebook, whatever. If I design a part in I expect it to be documented so I can at least talk to it if not reprogram it. But this is the wifi reality today, unfortunately. Someone(s?) was busy buying out and killing all documented wifi parts which used to be on the market at the beginning and nobody in the trade seems to notice or object that.

If you can skip the PIC, there is ready software for AVR32s. BR Ulf Samuelsson
