yaa that's cool , but cAn you tell me how to realize such a circuit in real time,, as in how to create one circuit that precisely controls the speed of the DC motor
what ever you start with pic/avr/8051 just don't start with arduino that's my personal advice .. coz you wont be able to learn much starting from arduino
and again personally speaking a good book to start with is " 8051 micro controllers by MAZIDI "
i have already posted the code in the first post itself as an attachment ..
here it is [[ it displays M D E to the lcd using two functions 1. lcddata 2. lcdcmd and a simple delay function
#include<htc.h>
#define _xtal_freq 16000000;
__CONFIG (0x2F0A);
#define ldata PORTD
#define rs RB0...
Nothing still ..
can you tell
1. how to define first port of PORT B in MPLAB using hitech c compiler for pic16f877a
2. what should be the configuration bits set
3. the xtal frequency defined
the hardware lcd i am using is on a development board so the pins Vss Vcc and Vee are already connected to the required terminals internally.There's nothing i can do in it except controlling the contrast through the potentiometer .
Can you please elaborate on the freq and config points , i...
these lines are written in the code ..
[[#define _xtal_freq 16000000;
__CONFIG (0x2F0A);]]
delay value given is [ 250 ] .. (as given in the code in the 1st pdf uploaded)
* do you want to make Xtal frequency =4mhz ?*
also please confirm that denoting first pin of PORT B by [[ RB1 ]] is...
yes, the code is working properly on ISIS,and yes the connections are fine too .
two things that are confusing me
1. the ISIS dig. for Pic16f877a and the one in data sheet are showing different positions of PORTD- 0 & 1 pins
2. are the < configuration bits > and the <XTal frequency causing...
Hello,
Please check the following HiTech C code for 16x2 LCD interfacing.
The 1st line of LCD shows blocks.The code is taken from the Samples and only the connection bits are changed.
But,its not working.
However,if I write similar code in microC,it works.So the connections are right.
Please...
