As usual , I arrived UTeM  at 9 am. Then continue with last task given by monday about gsm modem. To do the program, should understand the basic of PIC C. So today, I'm doing lab session 8 for embedded system communication. The objectives of this lab is to connect the PIC to the workstation using RS232 connection communication and produce output. There are several steps to program code for PIC to communicate with PIC via RS232 .

1. type the program code
2. the program is written with two kinds of error which are syntax error and logical error. Troubleshoot and solve them.
3. simulate the program using proteus
4. load the program to PIC using compiler and connect serial communication to PC using RS232 protocol.
5. open hyperterminal or putty.exe on the PC using 9600 baund 8bits data no parity, 1 stpop bit and no flow control.

Today as usual I arrived UTeM at 9 am and I continue the task given, about GSM modem. Still blur to program it in PIC C. After all, need to study the basic of PIC C programming for CCS. Try to understand why use C. After study ,C is portable language intended to have minimal modification when transferring to another uC. It also easy to understand and it is very efficient for complicated program. After study the fundamental, I tried to do lab session 6 for embedded system.Lab session 6 is about timer and interrupt. The objectives are to produce clock timing in CCS C compiler. It is also to write a system code in C to display clock on LCD simulation and hardware and lastly display triggered by the time set by the system clock.

Assalamualaikum , today as usual at 9am I arrived UTeM's main campus. I study coding using PIC C compiler. I have to study for GSM coding.

Monday , 16/7/2012

After built data interface cable RS232, today we still continue the task given about GSM modem. We have to understand about programming.

Seventh Day

Assalamualaikum, as usual at 9 o'clock I arrived UTeM. I've been given a new task which is related to PIC16F876A. Mr Mazran teach how to make RS232 Data Interface Cable. Black wire need to connect to pin number 5, and white wire need to connect to pin number 3 and lastly yellow wire need to connect to pin number 2.

Sixth Day

Assalamualaikum.. I still continue yesterday task.After set up GSM modem, we use AT command to sending and receiving message. There are steps in manual AT command.

Fifth Day

Assalamualaikum and good morning, 11/7/12, the new task given. We have to study the basic of GSM modem. As I know, GSM modem is similar to mobile phone. It accepts a SIM card and basically work same as mobile phone but it is for computer. GSM modem receive and transmit data through radio waves.
Mr Mazran teach us how to set up GSM modem.
