Did you mean pic and/or PLC? A mixture of lowecase and uppercase characters may lead in a misleading. Anyway, for both cases, considering that most gsm module interfaces are serial, I do not really see any issue there.
Hi all.. I am doing a project using pic167873a interfaced with gsm and GPS.The gsm module is interfaced with pic using UART. We are using mikroC. Not getting codes for GPS interface using SPI. thanks in advance
I am working on some sort of security system project. I need a gsm modem for the purpose of sending/receiving text messages. I haven't used any gsm modem yet so i don't know which one should i pick. Surfing the web gives me some models like SIM900/SIM900A/SIM900D & SIM-MINI. But i don't know whats the difference in them & which one should (...)
i am working on my project that switches off and ON home appliances using an android app that creats sms .The app can also request for power being drawn by the appliances through sending texts request that can be red by a gsm module. My gsm module is linked to a pic 18f4550 and my gsm (...)
I suspect the MAX232 circuit drives a module with an RS232 interface. The SIM300 needs a direct connection and would likely suffer damage if driven at the high voltages the MAX232 produces. Most pic devices when running on 5V supply have a high input threshold of 2V so data from the module should work fine. When driving the (...)
Yes. You have to connect GND of pic to GND of gsm.
Hello everyone.. As a part of my project, I want to take input from sensor and send it to pic16F877A MC,which sends an SMS through gsm SIM900A to another gsm module at the other side.Another pic MC at the receiving gsm module turns ON an LED , which is the output required. (...)
@Ivan Romo, On seeing the pic, i guess it is the normal SIM900 gsm modem, which can be accessed serially in the debug port which has a default baud rate - 11200,8,N,1. You meant that you want to flash your own code into the SIM900 module?? Flashing of your own application code cannot be done i suppose as i m not sure it is a Embedded AT (...)
why using max232 if you interfacing gsm to controller you can see the above link for simulation connection.

If you are new to gsm project then i recommend to use SIM300 module because there is lot of projects and help available on internet. And for pic uC, If you know how to program 18F series then choose any 20 or 28 pin uC or select 16F 20 or 28 pin which includes on chip USART.. pic16F877 is good for newbies and ready (...)
How you are interfacing energy meter to the pic ? If MODBUS through RS485, convert it to USART and interface with pic IF you want to simulate both gsm and Energy meter simultaneousely, you need two COM PIM and two COM ports/RS232 converters in your computer, one connected to the gsm and another to the energy meter. Virtual (...)
Hai friends, I am going to do a project based on pic16F877A controller, which reads the signal from a MQ-5 gas sensor, and the controller should send a message from a gsm module if there is a gas leakage detected and at the same time pic should close the solenoid vale connected to the out put port. can (...)

You can store it in array. So, example use while. I'm not Mikro C user but I have code in Hi-Tech and ChipKIT.
What are the voltage levels of logical of both the gsm modem and pic? What is the system clock frequency of the pic18F27J13? What are the baud rates of the gsm Modem and pic UART set? Does the gsm modem utilize any flow control? BigDog
Hi! I am working with pic18F26J50 and gprs/gsm module sim900 and right now im having a strange problem. Right now, we are sending from the pic to the sim900 an 'A' to configure the autobauding (8,N,1) and the sim 900 is responding correct the same letter A. After that, we are sending AT CR LF (with the correct ascci (...)
I don't know if proteus(version 7.2) have gsm module in their library . You have to connect it to the physical serial port of the PC using MAX232 IC. You can connect your pic to a serial port model in proteus which allows you to communicate with the device on physical serial port of PC.

Dear all USART have two option Synchronous and Asynchronous so which one we should use for communicate with gsm module
Some gsm modules can be rather picky concerning area, service and system available to you. You might want to specify a location?
Yes. Check this thread. Also you can refer gsm with pic18F4550
The tutorial is pretty clear. The gsm modules usually are using serial communication. What pic do you want to use? Have you find a gsm module? What language do you want to use??
Hello all I want to write program for pic in order to communicate with gsm module could you please send me code example thanks in advance
Hi everyone, i am new here. I am currently just about to start on my FYP project which is portable security system using pic. My idea is as below: The system will react to turning of door knob, pushing/opening of door/windows and movement in the house/building/hostel room/hotel room. When the system detect any of these activities desc
