Hey

if i look at the Firmeware i find for example this code to get, shift and send the accel data.

if (!inv_get_accel(data)) {

packetize_data(data, 3, 12, 'a', out);

eMPL_send_packet(PACKET_TYPE_DATA, out);

and the loop to shift in packetize_data() looks like

for (ii = 0; ii < num_elements; ii++) {

packet[ii*2] = (unsigned char) ((uint16_t)(data[ii] >> (24-q)) % 256);

packet[ii*2+1] = (unsigned char) ((uint16_t)(data[ii] >> (16-q)) % 256);

}

so far so good.

that means the the function calculates 24 - 12 and 16 -12 (= 12 and = 4).
(shift 12 and 4 times to the right.)

My Problem is now, that the output of this look like

"0,003 0,003 0,243" so there is more on the x axis wich is ok because of the grafity but the number 0.243 is not correct.

if i substract 14 and not 12 (shift 10 and 2 times to the right) i got a value about 1 for the grafity and that matchs better.

does that mean there is a mistake in the firmware? or what am i doing wrong...


ps.: on the "pc side" i just shift the first 8 to the left and the second 0
pss.: i hope you understood my problem in spite of my bad english...
