Sir,
For starters, you can buy an 8/16 bit PIC development board from www.microchipdirect.com or https://www.mikroe.com/pic/development-boards and start practicing.
You can get many documentation and support for PIC controllers...
The Programming IDE & Compiler also you can get for free...

Hi,
I am searching for an Energy harvesting solution to power my 3.3V, 200mA circuit. I am trying to store the energy from my motor’s shaft current which is driven by a Variable Frequency Drive (VFD).
The specs of the Shaft energy as follows:
1. Current – may go upto 5A
2. Voltage – Normally...
Thank you soo much engshahrul for your support...
BTW, I think I am now some what clear on Profibus. These are the two methods I am planning to use:
1. Using an ASIC like, SPC3, VPC3+C, DPC31, SPC42, LSPM2 or SIM1 with a MICROPROCESSOR Unit and a s/w stack (didnot know the cost yet - heard...
Thanx prakashvenugopal for your reply...
It really helps, also I got a MODbus stack for PIC controller too :smile:...
now I am very much concern about the Profibus..:sad:
It seems to be difficult to implement...
Hi,
I am sathya from Bangalore. I am an Embedded engineer and I need help regarding the Profibus and Modbus.
I am new to these communication protocols and I did my ground work on these protocols and their layers. I should say I am pretty much confused now.
My question is very simple:
1)...
Hi all... :|
first of all pls apologize me for asking this question.. I know there are circuits available for this in google... But I am confused and badly in-need of help from you guys..... :-(:-(:-(
here is my problem :
I am looking for a Signal converter which converts 0-5 VDC PWM output...
can you please upload ur circuit... Because i am lookin for such kind of circuit which converts PWM output (0-5 VDC) to current loop (4-20 mA) output....
ya please... me too want to know what is a DMA and its functions...
especially on the FreeScale ColdFire controllers V2... In MCF52235 datasht, it s specified as " 4 channel DMA ". what does it mean??
hav 2 start from the scrtch regardng ths issue... any help wil be apprciatd..
thnk u Colbhaidh..
i tried that prog in other compilers..
it worked...
i think this is the issue over c18 compiler that doesnt work...
sorry 4 d late reply...
thanx Colbhaidh for your reply..
i m uploading the hex file as wel as my c file.
it works on the MPLAB simulator but not in the pic18f sim.
I cannot upload these files as attachments. I m pasting it below.
file name : lcd.c
MCU: pic18f2220
# include <p18f2221.h>
# include <string.h>
#...
hello all,
As a part of my project I am using 16X2 LCD interfaced with pic18f2220. I wrote the code asusual and simulated in MPLAB simulator. It works fine. But, when I load the HEX file in the OSHONsoft pic18f simulator, it says STACK UNDERFLOW and stops.
When I dig the code and what I found...
