Experts,

First of all, thanks for your help throughout my project.

I am working on GPS based speed limit indicator and some navigation as well.

With your help, I was able to interface GPS module, antenna, 8051 controller and LCD.

Using my laptop and GPS receiver, I have saved information for different location and added "speed limits" and some "navigation information" for that.

This is saved in a text file, that is around 8kb(surely will increase, when I add more points).

PROBLEM:

1. I need ideas on how to retrieve the information from text file at run time using some 8051 microcontroller.

2. What type of external memory do i need to use to place the text file in?


I have done this all on laptop using 'C' but need ideas on how to implement the same on 8051.



thanks
 

The text file can be saved in a flash memory.

Most appropriate Flash is serial flash.

thank you AMK1971,

Do you think I should go for SD card, as my database size tends to increase later.


thanks again
 

Hi,
I need Implement simple database on Q2686 module , to store some data .
It has 60kB of flash. Can you tell me how to start the implementation of database on this ..?

Hi,
I dont want to use the external memory , I need to utilize the Module memory( If need I can go with module which has 128KB flash ) ..
My problem is to start the implementation of database on this module,. I dunno how to start the implementation.

if you need more memory then go for 32 bit controller LPC series. all have enough memory

bit P89c51RD2 gives the most memory
 
Hi,
Thanks for the reply ..

Kindly provide some links/docs which deals with implementation of database on microcontroller ...

Yes .. I need to develop this on a GPRS based gateway , where in this gateway has to collect data from wireless sensor network and store this data in local memory .. this gateway will receive queries from few users to see the data or upload to their server .
Hence I decided to go with the database on the Gateway.
