unwanted writting to the DAC for about 27ms
(shorter duration than the last 2 times I analysed it [around 50ms]),
Different value sent (0x6666 instead of 0x0001, both of them are unwanted, should be 0x7FFF)
0x6666 corresponds to F_20, which is 20% full speed foward
0x0001 corresponds to F_100, which is 100% full speed foward
0x7FFF corresponds to F_0, which is 0% full speed foward (AKA stop)
sends 5 packets
(vs 1 in 50ms [bug dac test delai apres lecture.txt] and 9 in 50ms [bug dac.txt])
