At all,
I have a doubt, How to select amplifier for my application..
1. sensor output is in mV, that one i want to use with 25 gain output.. calculation and all i am ok.
2. Single supply(+VCC and GND) or dual supply(+VCC and -VCC), Which one is better..
3. Operational amplifier or...
as off my required frequency is 10-200Hz, But the input for adc have frequency of inbetween 2Khz-5Khz because of noise,
Is there any way to control it via software or i have to go for hardware filter for attenuation of higher frequency signal?
What resolution / bit count.
I am reading battery voltage, and my ADC is with 12bit resolution.
What interface:
Built in ADC, i am using built in functions like read adc(); and all..
There is a way of measuring frequency with much bigger hardware with multiple filters. but its...
Thanks for the information KlausSt,
Edited by Dora: from now on, could you put quotation marks when you quote somebody?
I am familiar with PIC18F series controllers.
Every 1 Second i want to calculate frequency,
From the output of FFT, I want to measure RPM of an engine with battery...
Want to measure frequency with FFT,
Frequency range = 10Hz - 200Hz.
Frequency resolution = 0.5Hz
Which controller suits for this, and which FFT algorithm will give better results. I am new to this FFT concept. suggest your best...
Yes as you said like that i initialized, but for debugging purpose i kept that into while loop.

@ FenTrac Then what can be done? is there any alternative for compiler or MCU only we have to change?
I am facing this array initialization issue with PIC18F47k40. When i am initializing array with assigning values like
unsigned int array[] = {0,1,10,100,1000}; //All the values of array elements taking 0x0000 I saw with debug in watch and variable window.
If i assign like
unsigned int array[0] =...
Hi all,
I want to know the input digital value range of AD420, I need output of 4-20mA, I configured according to the requirement, AD420 is a 16(0-65535)bit DAC, but my adc values are 10(1023)bit, How to make my ADC values to compatible with AD420..
Thanks...
Dear chuckey i got what you said, But i need some more info about linear can you teach why its linear? why because linearity means a difference between successive elements will be constant, or something like a straight line, based on what its called as linear?

Dear chuckey...
I am driving relays of 12V and switching current they given as 1mA to 1.25A,
and power supply is of 12v 2 amps..

That recovery diodes i kept but how about the power supply? is that ok 2amps power supply?
