sir i want to download the bootloader software to my controlier board which was made by me ,the circuit schmatic diagram was downloaded from aurdino site using atmega 328 i have used parallel port to isp onte board but it is not able to download the bootloader it is showing error like
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
avrdude: Yikes! Invalid device signature.
avrdude: Expected signature for ATMEGA328P is 1E 95 0F
please help me
I hate to be the one to have to break the news to you but we really AREN'T psychic and we don't do Remote Viewing.
You will actually need to draw or post a schematic and your code and we may also ask for a photo of the circuit later if deemed necessary. But befor any of that we need you to post the complete part number on the top of the chip.
As raschemmel says, we need more information than that.
However here is how I installed a bootloader to a custom board:
As gammon says follow link. Thank gammon for sharing link
@thomas , if you designed your own board make ensure controller you have choosen.
atmega comes in atmega328p & atmega 328 p-pu. In all original arduino controller atmega328p-pu. Other vendor design using atmega328p model . both model are same but signature are different. cost wise atmega328p is cheaper.
http://www.instructables.com/id/Bootload-an-ATmega328/step6/ATmega328-PU-workaround/ simple instrction also given here.
sir can you tell me the signiture no of ATmega328P-PU which i am using in my circuit
Signature bytes are in the datasheet, in the Memory Programming section.
ATmega328 0x1E 0x95 0x14
ATmega328P 0x1E 0x95 0x0F << Arduino is looking for this.
Atmega328P-PU, '328P-AU, '328P-MU, will all be 0x1E 0x95 0x0F.
Same chip die used inside of different physical package.
sir i am sending the photos of pcb and the ic which i am using and also the procedure of how i haye done the downloading of bootloader software
I have no experience with parallel programming.
Which programming your using for uploading. Please ensure you choose proper programmer
FYI,
When posting for a compile error , please follow these instructions:
1- In the IDE, select "File\Preverences"
2- Check "Verbose Compiler output"
3- After attempting to compile and receiving error, drag the code window UP to expand the compiler output window.
4- Place mouse cursor over the red compiler output and LEFT CLICK (you will not see any change but this mouseclick is necessary
for the NEXT step.
5- Press and HOLD the CONTROL key on keyboard , WHILE pressing the "A" key. (this should highlight compiler OUTPUT ONLY)
6- Press and HOLD the CONTROL key on keyboard , WHILE pressing the "C" key (to COPY highlighted text)
7-Open Notepad and place the cursor in the Notepad window and Press and HOLD the CONTROL key on keyboard , WHILE pressing
the "V" key (to PASTE the copied text)
8-Post the Notepad file with the verbose compiler output as an attachment using the "Additional Options"button below.

I don't know where you found that Preferences file but if you read my post I said CLICK on "File" and select "FilePreferences"
in the IDE which would open a window (see attached screenshot) that has a little checkbox for verbose output.
how to use 2 analogue inputs for measuring 2 diffrent at a time and the result is shown in 2x16 lcd diaplay
i have written a programme it is showing 1 input data but not the 2nd one
LCD Programme*/
#include <LiquidCrystal.h>
int voltinput1 = 0;
int voltinput2 = 2;
int rs = 2;
int enable = 3;
int d4 = 4;
int d5 = 5;
int d6 = 6;
int d7 = 7;
int rows = 2;
int cols = 16;//enables 4 bit mode
LiquidCrystal lcd(2,3,4,5,6,7);
void setup(){
pinMode(rs, OUTPUT);
pinMode(enable, OUTPUT);
pinMode(d4, OUTPUT);
pinMode(d5, OUTPUT);
pinMode(d6, OUTPUT);
pinMode(d7, OUTPUT);
lcd.begin(cols,rows);
lcd.clear();
}
void loop(){
float voltValue1=5.0 *,voltValue2=5.0 *
analogRead(voltinput1)/1024.0;
lcd.setCursor(0,0);
lcd.print("I/P VOLT:");
lcd.setCursor(11,0);
lcd.print(voltValue1);
delay (500);
analogRead(voltinput2)/1024.0;
lcd.setCursor(0,1);
lcd.print("I/P VOLT:");
lcd.setCursor(11,0);
lcd.print(voltValue2);
delay (500);
}
Please edit your post, select the code, and put it between [code] ... [/code] tags.
You can do that by hitting the # button above the posting area.
