I am using Atmega 8 16 bit counter.
It works fine with the internal clock.
But when tryin to use a signal as external clock on T1 pin on the uC the pin stays high all the time.
DDRD &= ~(1 << DDD5); // Clear the PD5 pin
// PD5 is now an input
PORTD |= (1 << PORTD5)...
Yes it does... i have been working with the programmer and Atmega328P for the past 2 months... and yes i am able to program my uC with that hardware...

Thanx for this link.... but i dont understand this...
if i want to use the 20MHz crystal...
there is just too many...
**broken link removed**
this is the one that i use... and yes it supports Atmega328P
its just a GUI version of avrdude....
and it does have all options to read fuses and write fuses... but i dont understand what value to set... etc..

this is the programmer i am using and...

this is the software that i am using for burning programs...
Thank you guys so much for helping me understand about resetting fuse bits...
But what i want to achieve here right now is...
I want my atmega328P uC to work with 20MHz crystal
https://www.nex-robotics.com/products/electronic-components/crystal/20mhz-half-size.html
so i know i need to connect...
I have been working with my micro-controller for the last 2 months and i have had a bitter experience while setting fuse bits. I had to throw away one...
So now i need to work with an external clock of 20Mhz
i have got a 20MHz crystal and while reading the datasheet i have learned i need to...
In my project i have an ultrasonic receiver which gives an output of 1mV-10mV 40KHz signal
i need to trigger a pin of the microprocessor high when i receive this signal so...
I need an amplifier stage in between...
i tried an op-amp LM324 even though i get required uotmut in simulation, in...
one doubt...
from the datasheet i got this information
For a supply 2.4v - 5.5v the VIL threshold is < 0.3 * Vcc , VIH > 0.6 *Vcc .
As av example for 5 supply the low threshold is 0.3 * 5v = 1.5v and the High threshold is 0.6 * 5v =3v
what does that mean???
In the project that i am working on i need to detect a signal coming from the mic which is a very weak and in the range of 1mV.
So i need to know can my micro-controller detect that as a high on any port pin...
Or what is the minimum voltage that is required so that the uC can detect and...
hello...
I am working on a project with Atmega328P microcontroller and now i am in a place where i have to sent and receive data from pc to uC...
i am learning Qt Creator and am working in the C++ coding of the GUI....
i am clear with the uC programming part of serial communication...
I will...
i am using Atmega328P and i was trying to enable the PC6 pin which is set as reset by default...
And i am Using AVRDUDE GUI Burn-O-Mat v2 for this..
when i did it the first time it showed writing fuses successful but after that i tried to read fuses but it shows error...
tried to reset it...
thanx for all your time and for helping me in every way that you all could...:)
i did figure out what the problem was...
i just checked the board if there is power being supplied by the programmer... surprisingly there was only getting hardly a 1V reading in the multimeter...
and i was pretty...
