Thanks Mellis, I will try that!
47  Forum 2005-2010 (read only) / Development / How is the burning of bootloader done in 0010 on: November 08, 2007, 04:05:45 am
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?

I am using analog pins because I took the code from an example (Wiichuck adapter).

I have a Seeedstudio 433MHz tx/rx that I want to use with Arduino. The transmitter can be powered from 2-12V. Higher voltage, better range according to Seeedstudio.

I am not very good at drawing schematics with Eagle, but I threw together the one below.


I want to power the RF Transmitter with 12V, but not all the time. I want to switch power on and off through a transistor, a BV337-16 in this case. Switching is done through Arduino analog pin 2 (+5V) to collector and transistor emitter to analog pin 3 (GND). There is +12V at the base of the transistor. As soon as pin 2 goes high, the RF module should be powered with 5V.

At least, this is how I planned to do it. Is there anyone who can check the schematic and my explanation above to confirm it's correct?

Thanks in advance!

Try disconnecting the servo (and see if there is a way to verify if all other functionality still works). Servo's are power hungry...

My bad... didn't read to the end, I think...

Does this thread help?
