The Little "rAVeR!" Programmer

The Newbies MicroController Starting point. Covers Hardware and Software from an entry point of view. Many "Older" Engineers may learn from this also. And this is more cost effective than anything else going today.

<--- For users still asking: "Where are the schematics and list of parts"?
<--- Have a look at the local navigation links to the left of this text. It is all there.
Up a little bit OK? There are links in the grey text area.

Mega8's seem to work in the DT006 Thu, 29 Aug 2002"Alex Shepherd" @wave.co.nz>

Parallel Port is used for programing. Serial port is used for RS-232 Communications.

"rAVeR!"

The DT006 board will program the popular AVR Micro 8, 20, and 28 pin DIP chips on board, and will also program the DT107, (8515 and 4433 footprint) DT104, (2313 footprint) and SIMM100  (8535 footprint) AVR SimmSticks, as well as any AVR target board that has a Kanda type header. Current burning software is achieved with the programmer software built into MCS Bascom-AVR, HPInfo Codevision C, and Imagecraft C.

Check Bascom-AVR, Codevision, and Imagecraft documentation for chip types supported.

This means, after you have this programmer unit up and running as a development platform, all you need to duplicate the procedure with a stand alone micro, is a single AT90S2313-10-PC micro, and a DT104 PCB and a handful of simple components. Or you can use your own circuit design on a proto board, vero board, your own artwork, whatever.

The DT006 kit comes with a right angle 30 pin header which makes it easy to plug into a breadboard for proto typing, and allows the parallel/serial cables to be left on the DT006 as well.  This allows you to program larger chips without the need for the other simmstick boards ([E.g. program a 8535 or 8515)

Have a look at the bottom of the page at simcon.html for details of what can be done with the 30 pin connector.

This board is 3.50" by 3.95" and retails at $20AUD. ( $17USD recommended retail).

Any PC parallel printer port can be used to program the chip. You will need a DB-25-male to DB-25 female cable with at least pins 2, 4, 5, 11, and 25(Gnd) connected straight through between the DB-25 male and the DB-25 female. Standard DB-25 male to female extension cables that have all 25 wires connected straight through, are fine for this job. 

We now have assembled and tested units. These have a 2313 micro in a good quality machine pin socket, and a resonator to suit installed also in a socket. This will allow for alternative 8 and 28 pin micros installation also, and a crystal or resonator of your choice.

It sure beats buying those "stampy thingos" every time you want to get a new design going, or wish to duplicate an old one. And these things absolutely scream along by comparison. A 10Mhz AVR micro executes instructions at twice the speed of the 20Mhz PICmicro based BSII, and that's just the micro. As BASCOM-AVR  is compiled Basic, and not tokenized into a serial EEPROM like the BSII is, you have just speed it up by another factor of about 15-20 times.

What can you do with a DT006?

Programmer:
Let's forget about the SimmStick part of things for a moment, and look at the dt006 as just a programmer board.

You can program a micro installed on the DT006 board using a cable connected to your printer port with a standard 25 wire DB-25 to DB-25 cable, which is connected to the DB-25 connector on the DT006 board. The three 330 Ohm resistors are in line to your printer port signals. We recommend using good quality machine pin sockets for the micro and resonator, as these may need to be removed if you wish to program other micros with different pin counts, or operating frequencies. The basic kit configuration suggests a 20 pin AT90S2313 micro to start with.

You also need +5Volts connected to the micro, as well as the resonator and printer port connections, so you will need to build the power supply section of the circuit up also.

The DT006 bare printed circuit board at a cost of $20AUD (including postage) is a simple solution to make a simple AVR programmer. You can provide all your other parts if you wish.
DT006 board $20AUD. At current exchange rates, that's about $10USD including postage for this board.

If you order boards only, to a total of $20AUD or more, then  they will be air mailed to you free.
Other components will require additional postage costs, but we can get boards in a standard Air Mail letter.

Development Board:
Or you can look at it as a development board, as it has provision for switches, LEDs, and a 30 pin header on the end to jumper to a breadboard for proto work. See the picture down the bottom of the page at: simcon.html for an example of connecting a proto board to a DT006 board.

You can also program 8 pin and 28 pin micros by installing sockets in these positions, and removing the micro and resonator that comes with the kit, which is a 20 pin AT90S2313.
(Please Note. For SimmStick programming, the micro and resonator must also be removed.)

SimmStick Programmer:
DT006 can be used as a programmer for SimmSticks. These program in the Simm Socket that can be fitted to the DT006 board. You remove the Micro and resonator from the DT006 board and you can program a DT104 board that has these items installed.

There is a heap of info at: ssinfo.html on the SimmStick theme.

This will allow you to program the DT104, DT107, SIMM100, and SIMM101 SimmSticks via the Simm bus.
This covers the different footprints of the 40 pin devices, that is, the 8515, and 8535.

40 Pin Micro SimmStick Programmer:
A 40 pin 8515 can be installed into a dt107, or a 40 pin 8535 can be installed into a SIM100 SimmStick, and programmed via the Simm Bus.
