    Creating a Customized MODBUS Program for a Remote Terminal Unit

    I think I misread your Post. Modbus RTU is a Modbus over serial. If you are planning for Modbus TCP/IP, what you have to know is: 1. Who is going to send a request (it would be Client) 2. The one who sends a response to a request will be a server. The best way for this is, use Berkeley socket...

    Creating a Customized MODBUS Program for a Remote Terminal Unit

    Yes, you can write Modbus program using any language as long as you can access the Serial Port (you can use rs485 to USB). The best way to learn about Modbus is, to go through the Modbus specifications at modbus.org. There are some free source codes available. If you search freeModbus on...

    Converting decimal LAT/LON to NMEA format

    @camerart sorry I did not mean to laugh at you. I dont know what I was thinking. Try this link and hope it is helpful. https://groups.google.com/forum/#!topic/google-maps-api/xvDGvIidKQc

    Converting decimal LAT/LON to NMEA format

    lol. Cut and paste. You can connect PICs UART to a gps module and keep collecting ASCII buffers on RX line and convert it to decimal LAT/LON. Look into microchip MLA, you might find some examples.

    microcontroller or raspberry?

    Yes it is possible ,may be :p.. google microchip's dsPICs series, RAM might be a problem. Make sure you have enough RAM for your image or the other good option is go for the latest PIC32MZ which has dsp libraries.

    USART interruption

    if you need a constant duty cycle, yes you can use a timer with an interrupt to generate a square signal or other option is, you can generate PWM (google). I think that's what you asking, right?

    USART interruption

    Yes you are right. RCIF flag will be set as long as there is data in your receive reg. @Belhouss I am from USA.

    USART interruption

    when I execute the code, the interruption occurs correctly, the led turn on, after the interruption turns off correctly and the routine in the while continues its correct functioning. //I understood this But it is impossible to contact another interruption. //what do you mean by...

    esp8266 with avr

    First step should be:Try to make your serial interface work. could you format your code properly so it is easy to understand! Below link I though was useful. http://fab.cba.mit.edu/classes/863.14/tutorials/Programming/serialwifi.html

    How to improve upon this comparator driven LED circuit?

    1. Why is your VCC is changing? 2. What are your inputs? 3. What is purpose of R1?

    2 transistor circuit input output question.

    That was very interesting discussion..:).

    78l33 circuit regulator, thought it would drop a 5v voltage to 3.3 v but no!

    What is the input Voltage? Make sure if its 78L33. Do you a have a circuit?

    User friendly GUI for modifying PIC program

    You can write a script using groovy (n little bit of Java code). It has its own SDK, you can get more info from http://www.opensource4pic.org (Microchip supports this forum I guess)

    Interfacing between Little and Big endian

    You can write a function to convert a little endian into a big endian or vice versa. So when you receive a data from laptop, convert it into the compatible endian.
