minipov2 programming problems II

[ollifreund]

Hello,

I tried to make a Sound&Lightmachine from Mitch Altmans
guide on the net. Since every PC has a parallel port, I used
that one instead of the COM port. So what I did was using
ladyada's Minipov2 guide (http://ladyada.net/make/minipov2/hardware.html,
R21 is 47Ohms, right?) with the SLM modifications.

With AVR, I entered
avrdude -p t2313 -P lpt1 -c dasa -u flash:minipov.hex

and got

avrdude: ser_open(): cant set buffers for "lpt1"

I changed the makefile to use ltp1 instead of com.

Whats wrong?

Thanks!

"-c dasa" in your avrdude command line specifies the serial port programmer.

according to the Makefile for the minipov2 you want "-c dt006".

also you are missing the bit that tells avrdude what you want to do to the flash.

try

Code: Select all

avrdude -p t2313 -P lpt1 -c dt006 -u flash:w:minipov.hex

[ollifreund]

-> avrdude: cant find programmer id "dt006"


I changed "dasa" to "dt006" in makefile. Avrdude suggests
dasa, dasa3 and ponyser, but there are all serial port.

Lets say I soldered the whole thing wrong - what would
avrdude say?

Thanks!

[mtbf0]

it doesn't sound as though avrdude has gotten far enough to reveal a bug in your construction.

somewhere on your system there will be a file called avrdude.conf that has the definitions for all the programmers. no idea where it would be on a windows system, but i found the dt006 entry in mine.

it shows the following connections...

programmer
id = "dt006";
desc = "Dontronics DT006";
type = par;
reset = 4;
sck = 5;
mosi = 2;
miso = 11;
;

dont forget to run giveio.bat

[ollifreund]

I loaded giveio.sys. Found a GUI for avrdude, thats fun.
Without having the minipov plugged in, my laptop under
WinXP cant find the LPT1.
It either says "cant set buffers for lpt1" or "cant find
programmer id "dt006" (and names all valid programmers,
which are serial port or Atmel JTAG/AVR/...

[ollifreund]

Okay, I got it. In the .conf I just inserted the programmer tat mtbf0 pointed
out.
If I plug the minipov in, the first 2 LEDs light up, all others remain the way
they are. Avrdude says "device not responding, init failed, rc=-1", then
"avr device initialized and ready to accept instructions"...huh?

I'll check the soldering connections... can anyone check the 47 ohm resistor
I mentioned in the first post?

[adafruit]

did you build it from a kit?

[ollifreund]

Hello,

no, built it from scratch. My first project, I'm trying to teach myself that stuff.
For now I built this:
http://ladyada.net/make/minipov2/hardware.html

Exept:
R5-R8 and LED 1-4
VCC Sensor (whats that?)
JP1 (whats that?)

Avrdude accesses the LPT1, got 3V on the whole thing, LEDs are
in the right direction, no mistakes as far as I can see it.
Avrdude says that the device is not responding.

Whats wrong now?

[adafruit]

sorry, i can only provide tech support for people who buy kits. its just too hard to debug a project if the PCB and parts are different & i have enough customers who need help

[ollifreund]

Thats alright. Maybe someone else wants to take a look at it.
What are the minimum LPT pins for programming a 2313? I was
thinking of just connecting them and see what my computer does.

And whats VCC Sensor and JP1?

edit: haha! Take a look at Pin 1 and 20!

[The_Don125]

VCC Sensor is for if you wanted to put a hall effect sensor on the official PCB and use it for...stuff, usually for if somebody wanted to take the MiniPOV and use it on a bicycle tire or something as a sort of cheap SpokePOV.

JP1 looks like its just a header in case you wanted to use a replaceable battery pack. Since you wired the battery directly to the microcontroller pins, you don't need it.

[mtbf0]

you've got pin 20 in the wrong place. it's opposite pin 1. the pin you've got labeled as pin 20 is pin 11 and that is not where you want that little red wire coming from the battery.

[ollifreund]

Hey there,

I dont get it. I took new parts and soldered the whole thing again.
Giveio is installed, my laptop accesses the LPT, it always
says "cant detect the device".
I just built a very basic minipov2, I just want my computer to
access the Atmel.

Here is what I built:



Again, why is R21 200 Ohm? I did 47 Ohm.

Tomorrow I'll give it to a friend who is into electronics, he'll
take a look and debug the minipov.

Is the circuit above right?

Thanks,

Olli

[ollifreund]

Okay guys, I'm back

I was kinda frustrated in the past and didnt touch my project for a long
time. Now I'll try it again.

I rebuild the minipov 3 from scratch, now with the serial port. I've got
a Thinkpad on a docking station, Windows says I've got a working Com1.
(no USB converter)

I did the software like described at:
http://www.ladyada.net/make/minipov3/software.html

When I try t program it with make program-minipov,
avrdude says:



Looks like it cant open com1. Why is that?
