Led Matrix Board via SMS using Zilog encore 2 Years, 4 Months ago Karma: 0
Hello...Good day!
We are doing a design project entitled "Led Matrix Board via SMS".
We will use zilog as our microcontroller and sim900d to receive the messages sent via sms.
Our problem is we dont have that enough knowledge to make a code for the following requirements:
1. Display 3 or more messages with 160 characters each.
2. The message sent can only be displayed if the syntax is right (e.g. DISPLAY <MESSAGE>)
3. The gsm modem will send a reply as a confirmation whether the message was successfully displayed or not.
4. The current time is displayed at the end of each message.

Please help us... THANKS IN ADVANCE...

Have a good day

anemokid, from eleb ryt?

the first thing you will do is to parse the message (since there was checking).. if the parsed message is correct, then, separate the message for the display... but, you should create a sub functions where you are going to refer the letters of the LEDs...

Good evening sir!

Thanks for those information.

Actually sir, we have a code but it doesn't meet all the requirements. I attached it (zilog.c). It can only post 2 messages sent via sms. When you send another message, it will overwrite the first message. There is welcome message included in this code so we are planning to make it the 3rd message but we dont know how.

Can you check it sir?please.

The problem is we don't have the copy of the include files: functions.h, myuart.h, and GSM.h
That is why we cant load it to our zilog. We are trying to search it on the internet but we cant find anything.

We also dont know how to make the current time be displayed after every posted message.

Please help us Sir. Thanks! Have a good day!!!

it seems that your project is very complicated...

as i reviewed the conditions that you've given, you are going to display 3 or more messages with 160 character length.. have you done the hardware?
the message will be over writed if you have'nt store the previous message temporarily.. and concerning about the different .h files, you can try using #include <sio.h> (library for UART functions).

please inform us about the progress of your project.. and post your code here should there are any modifications..

Good luck!
