Mikroc Interrupts
Hi
how can we use serial interrupts in Mikroc PRO????
i want to send and receive data using interrupts but don't know how to use them
in mikroc.
i need ur help to solve this problem.
Thanx
first u have to select a GSM modem,there are two types of modem's
1.have built in TCP/IP stacku can establish a TCP connection by simply sending AT commands to modem
and the other in which u have to write an application for tcp/ip stack,which is a tough job i guess.
After that u have to send AT...
it means i have to use a battery(5v,580mAh) also for VCHG pin.
here is my power supply circuit for SIM300DZ please mention if there is problem
i need 3.3v for PIC,5v for GPS.
Thanx sabeti for replying
actually i want to use a NiCd battery pack (3.6v,700mah),but the charger given inmodule is for Li ion battery.Can i use it for NiCd battery .If so simply connect battery pack to VBAT via a limiting resistor and 5v to CHG pin.
plz give ur comment
i'm using orcad.
Hi
i am designing schematic for sim300DZ GSM module.Please tell me how can i design schematic for antenna pad connector and impedence matching circuit.also i want to know about backup battery and charging circuit ,i am attatching my schematic for sim300DZ interface.
Thanx
i have found a power supply circuit
GSM man please help me can i use this circuit for my power supply after making the changes,suggested by you in the thread.
my board will have a SIM300DZ nodule max 3.4-4.5v,3A
PIC18F65J15 max 0.3-3.6V,250mA
GPS receiver +3.5~5.5Vdc
can i use the power...
Hi
i want to design a circuit for Backup battery for my GSM module SIM300DZ whose max voltage and current values are 0-3.6v,250mA.
power supply Vin is 12v and For main power supply of module i am using the refrence circuit of the source power supply input given in SIM3XXDZ hardware design...
so u mean i can place it on my Board.
my concern is that some one told me you can't place it on a PC board having other modules.This module is packed in tin,he has told me that i have to use the matting of it's connector and than put that matting connector on the PCB.
i want my board like this.
i think this is not a difficult question infact very simple for experienced designers in the forum,still i can't get help..............
plz reply.......
Hi
i am going to design a vehicle tracker.i don't know much about PCB design.
actually I have to implement the GPRS modem and GPS receiver on the same board.
GPS receiver is GR-87-T0A by holux.
can u please tell me that is it possible to put this receiver on board.
i am attaching manual for this...
i am totally confused at present and don't know what to do:cry::cry:
my confusion is that i do'nt know whether there is a serial link built in the GSM/GPRS modem or not?
i have heared from someone that for SIM300DZ serial link is built in and you just send AT commands from PIC and establish a...
Thanx GSM Man
Plz tell me the sequence to establish a TCP connection and then send and receive data.May i use this sequence
**broken link removed**
i have tried this from hyperterminal
AT+CGATT=1
ok
AT+CGDCONT=1,"IP","ufone.pinternet"
ok
but after that it give error for AT+CSTT and AT+CIICR...
Actually i am trying to build a vehicle tracking system for my final project.
I am using PIC18F65J15,it has 2 EUSART modules.I am receiving GPS data on UART1 and using UART2 to interface with GSM module.
If i uses interrupts to receive data serially from GPS now how can i access the data...
thanx vijay for your reply
yes i am using GPRS.
plz help me how can i send a string on serial port........
i have found a function in pic mikroc UART2_Write_Text
can i send a complete string using this function.....
and how to add carriage return and line feed.
waiting.........
