In reply to Richie.

Hi Sorry for the late response
You could flash a custom recovery using Odin, and then you might be able to access the internal sdcard (and transfer the zip)
One of the options is CWM recovery or TWRP recovery.

You have to pass the image already marked for the code?!

It is not entirely correct to do this:
final int y = (int)((motionEvent.getX() / (float)view.getWidth()) * (float)sensorArraySize.height());
final int x = (int)((motionEvent.getY() / (float)view.getHeight()) * (float)sensorArraySize.width());
The problem is that aspect ratio of the sensor might not be equal to the aspect ratio of the texture view used for camera preview. What you see on the preview may correspond to just a part of the camera sensor, so in general case you need a more accurate mapping from texture view coordinates to active array coordinates.

Comment on Bootloading an ATmega88 for Arduino [w/ code] by Ella5471

In reply to Hasan. Either things have changed since this post was originally made, or the author got a couple things wrong. I managed to get the bootloader burned to the ATMEGA 88, but I had to do a lot of trial and error as well as some revising of the boards.txt code. There are some extra bits required for the Arduino IDE to be able to upload code to the 88. You need to add the upload tool, and the burn tool, and a few other things. Look at some of the other boards listed in the boards.txt to see what is missing. Also, make sure to do the burn via the command line and not through the IDE so you can use verbose mode and modify the parameters of the burn.

Hi, great article. Is there an available python implementation of this?
