Did you ever get the dr3100 to work with Arduino? If yes, would you care about how you connected it and show some of your code?

Can you upload just the hex to your Arduino? Or comes the mini without the icsp header?

Great!

Thanks for your help Mellis!

It took some time, but I have finally found out that setting upload.verbose to true does work.

I copy/pasted the contents of the output window to Notepad and was able to find 2 AVRDude commands:

Code:

C:\Program Files\Arduino\Arduino-0010\hardware/tools/avr/bin/avrdude -CC:\Program Files\Arduino\Arduino-0010\hardware/tools/avr/etc/avrdude.conf -v -v -v -v -pm168 -cstk200 -e -Ulock:w:0x3F:m -Uefuse:w:0x00:m -Uhfuse:w:0xdd:m -Ulfuse:w:0xff:m

C:\Program Files\Arduino\Arduino-0010\hardware/tools/avr/bin/avrdude -CC:\Program Files\Arduino\Arduino-0010\hardware/tools/avr/etc/avrdude.conf -v -v -v -v -pm168 -cstk200 -Uflash:w:hardware\bootloaders\atmega168\ATmegaBOOT_168_ng.hex:i -Ulock:w:0x0F:m

Is it correct that the first command unlocks the processor (fuses?) for burning and the second command burns the bootloader and sets the fuses again?

I should be able to use the 2nd command, replace ATmegaBOOT_168_ng.hex with my own .hex file, to burn .HEX files generated by the compiler in the IDE?

Unfortunately, it looks like there is nothing shown when setting upload.verbose to true. I am expecting this to see in the bottom part of the IDE or in the DOS box that opens when you start run.bat

Any ideas?

Thanks Mellis, I will try that!

Anyone can enlighten me on how the burning of bootloader is done in the Arduino-0010 IDE? I couldn't find a batchfile of config file with information about that.

I am currently using uisp to burn hex files, but that doesn't seem to work correctly. I don't get errors after flash, but for example the bootloader or a blinking led firmware doesn't work.

When the bootloader is burnt from within the IDE, it does work...

I hope someone can help!

Does that happen all the time or every once in a while?

I am experiencing similar problems on a new Windows 7 x64 install. Sometimes it happens during the upload, sometimes during the verify cycle. I can see that because the led on the Arduino stays on.

In my case it is a complete hang of the system, I have to power down and restart the laptop.

Thank you very much!

Like the title says, can I burn .hex files through ICSP into an Atmega48 (or Atmega88, etc...) if I put one of these chips in an Arduino board?

Was this every solved?

I have a Nano V3 (new in box) that gives the same data with USBView as reported by TS. I would love to hear if and how it has been solved?

Edit: I need to add that mprog/ft_prog doesn't find the device.

Thanks for the explanation. Can you suggest a FET. In the mean time I will use google to see what a FET is/does.

Here is how I use the Analog pins 2 and 3.

In setup:

Code:

pinMode(16, OUTPUT);   // +5V - Arduino analog pin 2
pinMode(17, OUTPUT);   // GND - Arduino analog pin 3

I have 2 functions to power on and power off the rf transmitter:

Code:

void powerOff()
{
  digitalWrite(16,LOW);
  digitalWrite(17,LOW);
}


void powerOn()
{
  digitalWrite(16,HIGH);      // Pin 2
  digitalWrite(17,LOW);       // Pin 3
  delay(1000);  // wait for things to stabilize
}

So, I understand that I should use digital pins? I have been using the same code with analog pin 2 and 3 when I powered the RF transmitter with only 5V. Because at 5V the distance I need is not enough, I switch to 12V by using the transistor.

I hope to do some more testing this afternoon.

Thanks all.

I did exactly as above (incl. Lefty's suggestion), but it doesn't seem to send anything. Will do some more testing tomorrow.

I will post again when I have more information.

Thank you for your reply BenF,

I have it like this now:


Pin description of RF Module:
Pin 1 - VCC
Pin 2 - Data
Pin 3 - GND
Pin 4 - Antenna

You mention a 2.2K resistor, I have 2.5K. Should I get a 2.2K for this?
