mems tilt operated mobile

[riya]

hello every one,

i'm using pic 16f877a controller. and also i have one mems module. i want to calculate the tilt by which i need to send a message through GSM modem.

please help me where to start and how to develop this application?

my software is proteus 7 professional

help me regardin this.

do the following in order...

1) get rid of Proteus..

2) buy real parts..

3) cut code and show us, we will help

here's why

1) Proteus is FULL of bugs, errors, faulty DRCs and will never EVER 'simulate' the PIC correctly.

2) only REAL PICs work properly

3)Guys here have tens of thousands of manhours cutting real code for PICs,real PICs.No one here can or will try to debug Proteus 'code'.Sure, it may look ok but 'inside' Proteus is a lot of bad,faulty code.


so...once you get the real PIC, breakdown the project into steps...
1) read, read some more,get familiar with the PIC, cut the 'hello World' and 'blinking LED' type programs..

2) read some more, get the PIC to talk to the 'mems module' and display data to a local LCD or send to PC terminal program...

3) read some more, get the PIC to talk to the GSM module..

The 'trick' here is to read, read and READ again! The more you read and understand the better and faster you'll appreciate PICs and the CCS C compiler.

thanks for your help.

Hello sir,

i have followed you suggestion.
i purchased the modules.
and tried the code as you said divided my code into parts and finally i get the code like this.

please have a glance and tell me the mistakes.
thank you.[/code]




*****************************************************************
I assumed,
if no tilt i.e x,y=0 lock the phone.
if y==3\\ tilted down - phone book, call window, message window
if x==5\\ tilted left - scroll contacts
if x==10\\ tilted right - dail a number
if y==6\\ tilted up - home

please use the "code" tags to post code in the future.

Three things I noticed off the bat:
1. You don't use ERRORS in your #use rs232() call like you should be. That needs to be fixed.

2. You use PIN_D0 for both I2C and the LED.

3. Just a format issue: led should be LED or something capitalized. Constant names should typically be capitalized for readability...not an issue with performance though.

I can't really read the rest of your code well enough to spot other things due to the format.
