Now that I have my little app, it was easier to test with the protocol.
When there are 3 fingers, there is only one coordinate reported, and it
is done in the same way as with one finger.
There might also be some additional info on the 5th and 6th bit of byte
3, and 5th to 8th bits of byte 4. No idea yet what they correspond to.
Cheers,
Eric
