Anyone using Arduino Leonardo ?

Post by penniejf »

I have the leonardo, connecting it to CP2102 according to one of the thread. But I didn't found any information on how to install the firmware into leonardo.
This totally beyond my knowledge, and I am afraid to do some stupid thing to damage anything..........Is there anyone built the adapter using leonardo? I need some help. :|

As suggested by niema in the other thread, you can use the arduino builder GUI.

There's a detailed tutorial at http://www.arduinodev.com/arduino-builder-tutorial/

Thx matlo.

Niema's suggestion surely helped me a lot.
I tried Arduino Builder, but I failed flashing the atmega32u4.hex into my leonardo. I don't know why that happens.
Only one log came out in Arduino Builder as
Forcing reset using 1200bps open/close on COM3... no new port found

Now I am worried about my initial bootloader might be corrupted.
Since I can't upload any code into my leonardo.
Here is some bug info down below.
Binary sketch size: 4,242 bytes (of a 28,672 byte maximum)
Found programmer: Id = "Br¥"; type =
Software Version = . ; Hardware Version =
avrdude: error: buffered memory access not supported. Maybe it isn't
a butterfly/AVR109 but a AVR910 device?

I am sure the leonardo uses AVR109, guessing its corrupted already.

I changed a USB port, and this time the leonardo has been assigned to COM5.
This time everything works fine, and windows XP has found the game controller, named LUFA Joystick Demo.
I guess the firmware installation is successful, right?
