The sensor has to be provided with a supply and ground.
I want to use the op-amp to reduce any non-linearity that might occur. The op-amp buffer or differential amplifier will reduce such possibilities and provides good output impedance.
Hi,
I am thinking of two ways to implement the above circuit.
First is in the first image, where I use a resistor to convert current to voltage and use Op-Amp buffer.
Second is in the second and third image, where I use a differential amplifier to shift my output voltage to get better range...
Hi,
I am trying to interface a pressure sensor with 4-20 mA output with an ADC. So I have to convert this current to voltage.
But the problem is that I have a single supply of 5V and I want to use LM358 single supply OP-AMP for this conversion. I successfully implemented the circuit using...
Hi all,
I am using Infrared reflector type Optical sensor to measure speed of the motor.[i.e a radium sticker on the shaft that reflects the infrared beam, because of which I get a pulse for every one rotation].
The basic idea is to measure no. of pulses per second, then multiply with 60 to get...
Hi,
It looks like it is not accepting any Configuration settings. It is giving same warnings. The code is still not working.
Please let me know if the below statements are correct, because it is giving "unknown pragma "config"
/*******CONFIGURATION SETTINGS********/
#pragma config FOSC =...
I changed
#include <pic.h>
to
#include "PIC18F45K20.h"
It accepted. But when I did initializations as below,
#pragma config FOSC = INTIO67
#pragma config WDTEN = OFF, LVP = OFF, MCLRE = OFF
it gave following warning:
Warning [335] Q:\Projects in Hand\Strain Measurement-StrainM\Product...
Hi All,
I have started to PIC18F45K20 Demo Board that comes with PICKIT 3.
I am trying to use MPLAB IDE with PIC18F Hitech Compiler Lite Mode.
When I am using the following statement:
#include <pic.h>
it is giving following error:
Error [141] Q:\Projects in...

I have never worked in mikroBasic or mikroC. I have only worked in MPLAB Sim. So I cant help it.
Where did you get Lcd8_Cmd() and Lcd8_Out() ? From the code that you have attached, I believe the first parameter decides the Line of the Display. Can you give the original code?
Actually you...
I have attached a sample code of the LCD interface with 4 data lines. It uses PORTD and PORTE for interface. Change the IO to your requirement.
For other two lines, try using the following as the starting address of the lines. You should first send the address of the location you want to...
You should check your Initialization code of your display. Or may be the address you are sending for 2nd and 4th line may be wrong. Try different address and check for the correct one.
