bootloader uploading into Atmega328

Question

Here is mine circuit. Intially i used arduino UNO directly for programming. Now i am Using atmega 328 IC for programming. I am trying to connect 32 hall sensor via Mux circut. I wanted to How to upload boot loader or HExfile Here. Will avr pocket programmer satisfy above circuit or i need to add addtional circuit here AVr pocket programmer

Answer 1

The AVR pocket programmer should work fine. Sparkfun has a good guide for doing this.

Here's the pinout of the Atmega328:

You'll want to connect your programmer as follows (note, these are the pins for the bare Atmega328 chip only. The pin numbers on an Arduino board are different.):

Programmer Pin		Atmega328 Pin
5V			Vcc (7)
GND			GND (8)
MOSI			Digital 11 / Physical 17
MISO			Digital 12 / Physical 18
SCK			Digital 13 / Physical 19
Reset			Reset (1)

Note that the physical pins on the chip are numbered differently than the logical pins. In the table above the "Digital" pin numbers are those colored yellow in the figure, while the "Physical" pins correspond to the black-on-white numbers around the edge.

If you already have the ICSP header connected to those pins (it's not completely clear in the schematic if that is the case), you can connect the programmer to those pins instead. This can be easy if you have a 6-pin ICSP cable with your programmer.

Also, if you are already powering your Atmega328 from some other 5V power supply you can omit the 5V-Vcc pin. However, the programmer and the Atmega328 must share a common ground, so be sure the GND pins are connected.

Connect your programmer to the computer using USB, open the Arduino IDE, select the correct serial port of the programmer, and pick "Arduino Uno" in the "Board" menu. You can program the bootloader by selecting "Burn bootloader" in the Tools menu, or you can simply write your program by selecting "Uploading using programmer" in the File menu.

Uploading Hexfile to your arduino can be done using this application:

This is how you upload an Arduino Bootloader on an empty ATmega328 / ATmega328P-PU. Using an Arduino. (No need for a separate ISP Programmer).

From Arduino Uno to other Arduino Uno.

1. Open the ArduinoISP firmware (in Examples) to your Arduino board.
2. Select the items in the Tools > Board and Serial Port > Arduino Uno.
3. Upload the ArduinoISP sketch.
4. Wire your Arduino board to the target as shown in the diagram below. (Note: you'll need to add a 10 uF capacitor between reset and ground.)
5. Also connect TX from Arduino A to the RX of Arduino B and RX from Arduino A to TX Arduino B.
6. Select Target Board in Tools > Board > Arduino Duemilanove w/ ATmega328
7. Select programmer in Tools > Programmer > Arduino as ISP
8. Use the Burn Bootloader > Arduino as ISP command.
9. Go to Tools and Select Burn Bootloader. Done.

To upload on a breadboard without External clock.

1. Download: Breadboard.zip
2. Put boards.txt in your Arduino directory under Hardware > ATmega328. (For windows usually (C:/Program files/Arduino/Hardware/ATmega/boards.txt))
3. Close Arduino IDE and reopen it.
4. Open the ArduinoISP firmware (in Examples) to your Arduino board.
5. Select the items in the Tools > Board and Serial Port > Arduino Uno.
6. Upload the ArduinoISP sketch.
7. Hook pin13 from Arduino to pin19 on Chip
8. Pin12 from Arduino to pin18 on chip
9. Pin11 from Arduino to pin17 on chip
10. Pin10 from Arduino to pin1 on chip
11. pin0 from Arduino to pin3 on chip
12. pin1 from Arduino to pin2 on Chip
13. connect 5V from Arduino to pins 7 and 20 on chip 14, connect GND from Arduino to pins 8 and 22 on chip
14. Select Target Board in Tools > Board > ATmega328 on breadboard (8 MHz internal clock)
15. Select programmer in Tools > Programmer > Arduino as ISP.
16. Select Tools > Burn Bootloader. Done.

It's also possible with an Arduino Leonardo but you'll have to change some settings for that.

Note: You will need to put target board to Arduino Duemilanove w/ ATmega328 for programming the new chip (Uploading a code to it) instead of targeting Arduino Uno.
