  1. [SOLVED]Closed: Re: PIC serial port receive Problem, please help

    Why don't you reserve a 200 or 300-byte buffer and receive the whole GSM response data for a command and then parse it and do whatever is needed?
  2. [SOLVED]Closed: Re: PIC serial port receive Problem, please help

    He mentions simulated.
  3. [SOLVED]Closed: Re: PIC serial port receive Problem, please help

    That is because in Proteus Virtual Terminal "\r\n" is not sent and you cannot send it. In real hardware the GSM commands and responses will contain one or more pairs of "\r\n".

    It is exactly Omron G3MB-202P

    My Robu.in relay board doesn't have opto-isolator but why that is needed when the internal of the SSRs are already opto-isolated?

    @Klaus

    Good answer.

    You are right.

    My SSR module uses this SSR and it is ZC type.

    Remote Controlled Switch Board Issue

    See attached circuit.

    This is the circuit which I designed.

    The issue is there is no common GND between VSINE (220V Neutral) and 5V circuit GND.

    In the for() loop local variable j goes from 0 to 9 and when it becomes 10 the loop breaks.

    Zip and post the complete mikroC PRO dsPIC project so that the Oscillator settings could be examined.

    Post your circuit and also your Keil complete project files.

    Also, mention what is your Crystal frequency, 12MHz, 11.0592MHz,...?

    Very simple. Try this.

    I now guess it is only hardware issue.

    The dev board lacks a POT for the contrast.

    Maybe you don't know how to zip and post a complete Keil project.

    You have attached only .uvproj file. What is the use of it without other project files?

    Yes, it can be done. UART to UART with or without RS232 it can be done. If the distance between 8051 and Arduino is small then you can use the TTL UART interface.
