Help me with EasyWIFI board

[Akanbi Ibrahim]

Please i want to interface EasyWIFI board that carries MRF24WB0MA Wi-Fi radio transceiver module with my microcontroller

Hi,

I like that board. Really nice.

It can be connected to a MCU via SPI bus. Do your MCU have SPI interface module? Which MCU are you using?

[Akanbi Ibrahim]

Thank you very much sir for your urgent reply.do you actually know that you  are the first person for two months that has given me confidense that i can achieve this project.Actually the project is that i want to get an input from my temperature sensor and send it over to my computer wirelessly and this can now be view as a page on my browser.My supervisor travelled out and bought an EasyWIFI for me for the wireless transmission.I have done the temperature sensor i.e LM35 aspect of interfacing it with my 8051 Microcontroller.It now remains me to interface it with d EasyWIFI and then my host computer.

[AJISH ALFRED]

Alright, but you know the 8051 don’t have an in-built SPI module.

Since it also not having an ADC module, you might have interfaced the LM35 through an external ADC, right?

But there is nothing like external SPI module. Ofcourse you can simulate the SPI module using your code, and using few I/0 pins. Believe me its too difficult.

 

Better you choose a microcontroller having both ADC and SPI.

 

You WiFi board is a high end device, why are you trying to interface it with such a basic microcontroller?

[Akanbi Ibrahim]

Sir,what about AT89S52,I read it has inbuilt SPI.which are P1.5/MISO,P1.6/MOSI and P1.7/SCK.It is because i am use to 8051 microcontroller and that is the reason why i am using it and i have already done the LM35 interfacing with it.But if you have any suggestion for the microcontroller i should use and how i am going to handle it,i will be very greatful sir.Thanks

Hi,

In 89c52, you can use SPI only for serially programming the flash. As far as I know, it can’t be used or programmed for SPI communication.

I suggest you to use PIC18F series, like PIC18F8722. It has all the necessary hardware modules.

[Akanbi Ibrahim]

Thank you for the suggestion sir.I will be very greatful sir if you can give me a guideline on it.i will further my own research too on it.

[AJISH ALFRED]

Hi Akanbi,

Thats great. Well I’ve done most of my work in arduino and an industrial standard microcontroller called Renesas.

But I’ll try to help you as far as I can.

 

Learn about the SPI protocol first. Then learn how it is implemented in this particular controller. Which all registers are associated with it, what should be their values etc.

Then try to implement it in your code.

There should be doubts, and you just post it here.

[Akanbi Ibrahim]

Good day Sir,i have gone far to buy a board which is EasyPIC7.So it comes with PIC18F45k22.So i am using the board directly now and it has Microbus for SPI and I2C interface.

[AJISH ALFRED]

Good day Akanbi,

Thats really nice. I wish to have updates of your project. I can see you are working hard on the project, and hence you will learn lot of things and I’m sure you will get the final result soon.

Any help needed, just post here!!
