Source code for the G1 multitouch proof-of-concept posted

Anyone interested in exploring how the device tracks the two fingers can grab the source and play with it.

It looks like the stuff you uncommented is just debug code, and the driver is still in fact reporting 2 finger tracking:

if (z) {
	input_report_abs(ts->input_dev, ABS_X, pos[0][0]);
	input_report_abs(ts->input_dev, ABS_Y, pos[0][1]);
}
input_report_abs(ts->input_dev, ABS_PRESSURE, z);
input_report_abs(ts->input_dev, ABS_TOOL_WIDTH, w);
input_report_key(ts->input_dev, BTN_TOUCH, finger);
finger2_pressed = finger > 1 && finger != 7;
input_report_key(ts->input_dev, BTN_2, finger2_pressed);
if (finger2_pressed) {
	input_report_abs(ts->input_dev, ABS_HAT0X, pos[1][0]);
	input_report_abs(ts->input_dev, ABS_HAT0Y, pos[1][1]);
}

pos[1][0] and pos[1][1] is the position of finger 2, and pos[0][0] and pos[0][1] is the position of finger 1.

They are populated in the loop:

int p = buf[base + 1];
...
pos[f][a] = p;

My guess is that the C++ framework code and Java code need to be tweaked to handle multitouch (with no changes to the driver at all). I'm not too familiar with the code. Have you figured out how the input_report_abs gets handled?

I am afraid this is becoming *ALSO* a legal issue now :
