Hi Rishi,

I wanted to know if you had any experience using MPLAB and the Pickit family of low cost programmers under Linux? Does Microchip have any plans to port MPLAB to Linux and Mac?

I was considering going from Windows to Linux permanently and I just wanted to make sure I could still run MPLAB to program my Dspics. I'm currently running the latest version of Ubuntu 10.04 Lucid Lynx.

Thanks for your time.

Hi Rishi....

I have a fishing boat that I can steer electronically:  if A is logic high, the boat turns slowly to port; if B is high, it turns to starboard; if both are the same (high or low) the pilot motor stops.  But I want to rig it as fully hands-off.  I am looking at an angular rate sensor gyroscope.  Isn't there some way that I can use it to provide the logic to hold the boat on a steady heading?  I have all the servo parts working fine.  Many thanks for your help, or, if I have attacked the wrong expert, can you shift this problem to another one....

Dear Rishi,

Im final year student and doing a project for button detection.

I want to program PIC18F452 using mlab version 8.3.3 and CSS C- compiler.

Actually Im beginner.

What should I do?

Could you teach me and give me a basic example to make sure that I already used the right software and compiler.Im really blurr about that.

Thank you for your help.

Hi Saara....

I have Sure Electronics dual-axis magnetic sensor module with UART and I²C interface.  Can you recommend a µcontroller or processor to use with it to develop a magnetic compass project?

Many thanks...

Hi Saara,

PIC18F452 is an old PIC. you should better use PIC18F4520-E/PPIC18F4520-E/P which is pin to pin compatible and more recent.

Regarding MPLAB, I recommend that you install the latest version v8.63 as your version is quite old...

Regarding the compiler unless you alrady have CCS compiler you could use C18 compiler LITE version which is free.

There are much more examples with C18 on internet ;=)

Hi Bruce,

you can check this application note : AN996 with PIC18F2520.

Hi Rishi,

     I am a student of the national program, Project Lead the Way. I am in the Engineering Design and Development section of the four years I have been in PLTW. We are trying to design and build an invention. We have encountered a roadblock that we hope you will be able to help us with. We have someone developing our program, but none of us have any knowledge of PCB assembly and what to use for our invention, can you please help us? Contact me at pltw.ldumont@actcstudents.org

if you can.

Hi,

I am trying to transmit and recieve block of few bytes through USART. I am using PIC18F452 and PIC18F252 at two kits. I am programming in assembly language. Tranmission is @1200 baud and Procesoor clock @4Mhz.

My problem is,

I cant recieve byte unless insert a delay at transmitter. But it slows the communication. What could be the solution ?

concerned code is copied here. How to speedup the communication eliminating <<Delay1>> between consecutive bytes.
