AVR MICROCONTROLLER PROGRAMMER

Thank you for using this AVR Microcontroller programmer. The AVR microcontroller family comprises of

8-bit RISC microcontrollers with speeds up to 20 Mega Instructions per Second (MIPS), surpassing the

performance limits of commonly available 8-bit microcontrollers (e.g. AT89x and PIC). The AVRs are a

balanced choice for embedded applications and lie at the break even of performance and system cost.

This programmer uses a standard COMM Port (Serial Port) and can program numerous variants of the

AVR family. The programmer uses ISP method for programming the microcontrollers. A list of all

supported devices is given in Table 1.

Table 2 enlists the AVRs that can be programmed using the on-board ZIF sockets. It is worthwhile to

note that all the devices in Table 1 can be programmed using the ISP connector provided for the

purpose.

devices mentioned in Table 2. If desired, the schematics along with the latest software can be

downloaded from the Pony Prog website www.lancos.com.

Brief Overview of Jumpers and Connectors

This section details relevant information regarding jumpers and connectors on board. It is advised to

review this section with utmost care since wrong installation of jumpers, or incorrect combination of

ISP signals may render the microcontroller totally useless or locked.

Connector for PC Serial Port:

The host PC connects to the programmer through this connector. The pinout of the serial port connector

is as follows.

Connector for ISP:

The ISP connecter provides all signals needed to program AVRs outside the programmer, thus

eliminating the need to put the target chip in the programmer. The ZIF sockets are compatible only with

AVRs specified in Table 2, thus for greater flexibility and true In-System Programming, these connections

may be extracted from the programmer board without zeal. Furthermore, some AVRs, even though they

are supported in software, must be programmed outside the programmer using the extracted ISP

signals. Examples include AT MEGA 64, AT MEGA 128, AT TINY 26 etc.

Jumpers J1, J2, J3 and J4:

N.B.: Review the following section with care as incorrect placement of jumpers may destroy the

microcontroller.

Jumpers J1 through J4 select the type of microcontroller based on its structural resemblance to a

particular type. For example, ATMEGA8515, ATMEGA161 and AT MEGA162 have similar pin out

therefore they can all be programmed through the same jumper configuration. Below are the

programmer diagrams showing how various AVRs can be programmed through their corresponding

jumper settings.

Jumper Setting #1:

Figure 1: Jumper Setting #1

In setting #1, jumpers are placed in locations J1 and J2 as shown in Figure 1. Note that the AVRs need to

be placed in ZIF #1 to be programmed successfully. Also note the orientation of the AVR in ZIF Socket #1.

List of AVRs programmable in this mode is below.

1.ATMEGA85152.ATMEGA1613. ATMEGA162

Jumper Setting #2:


In setting #2, jumpers are placed in locations J1 and J2 as shown in Figure 2. Note that the AVRs need to

be placed in ZIF Socket #1 to be programmed successfully. Also note the orientation of the AVR in ZIF

Socket #1. List of AVRs programmed in this mode is below.

Jumper Setting #3:


In setting #3, a jumper is placed in location J3 while there is no jumper in any other location as shown in

Figure 3. In this mode ATTINY2313 can be programmed through ZIF Socket #2. Also note the orientation

of the AVR (AT TINY 2313) in ZIF Socket #2.


7/18

Jumper Setting #4:


In setting #4, no jumper is placed in any location as shown in Figure 4. Note the orientation of the AVR

in ZIF Socket #2. List of AVRs programmed in this mode is below.

1. ATMEGA82. ATMEGA483. ATMEGA884. ATMEGA168

Jumper setting #5:


In setting #5, a jumper is placed in location J4 while there is no jumper in any other location as shown in

Figure 5. Note that the AVRs need to be placed in ZIF Socket #2 to be programmed successfully. Also

note the orientation of the AVR in ZIF Socket #2. List of AVRs that can be programmed through this

mode is below.

1. ATTINY122. ATTINY133. AT TINY154. ATTINY225. ATTINY256. ATTINY457. ATTINY85

The Software

The programmer uses Pony Prog to burn hex files into the AVRs. Pony Prog can be installed from the

accompanying CD. Latest version of Pony Prog can also be downloaded from www.lancos.com.

However, this programmer is tested using Pony Prog software in the accompanying CD. After installing

Pony Prog, carry out the following steps to configure Pony Prog with your PC.

1. When you first open the program, you will get a screen similar to the one given in Figure a.

Figure a

2. Next go to interface setup as shown in Figure b and then set the interface to SI Prog IO asshown in Figure c.

4. Place the ATTiny2313 into ZIF #2, keeping in mind the orientation of the IC as well as theplacement of jumper in location J3, as discussed in Figure f (Jumper Setting #3).

5. Erase the AVR, by going to Command menu and clicking Erase, as shown in Figure g. Iferased successfully, a message box will appear confirming a successful clear operation as shown

in Figure h.

8. You can save yourself from the hassle of explicitly selecting Erase and Program from theCommand menu every time you program an AVR, by following the steps in Figures p and q. Go

to Command and click on Program options. Check mark Reload Files, Erase, Write program

memory [Flash] and Write Data Memory [EEPROM]. So whenever you want to program the AVR,

just press CTRL-P and the AVR will automatically be erased and programmed.

Important points to note:

1. Prior to changing fuse settings, please review the datasheet thoroughly, of the microcontrollerthat you are working on, especially the section containing fuse settings. If you set a wrong

combination of fuses, the controller may get locked and will only be unlocked using a High

Voltage programmer.

2. When you program your controller for the first time, it is running on internal oscillator. If youchange its setting to external crystal or resonator then a crystal along with its stabilizing

capacitors must also be soldered into the board.
