I'd already done it, but it didn't answer my questions. I tried
redownloading Firmata-2.1beta7 but from firmata.org and it worked
fine. I dont' know what could happen.
Another question:
It's ok if I modify line 38 of "StandardFirmata" and change the
samplingInterval from 19ms to, for instance, 1ms or 0.5ms or it'll
be useless or dangerous?Thanks for your work, it's quite helpful. Ignacio
That 19ms timing is carefully tuned to best handle the FTDI USB-serial
chips buffers. Making it lower, especially as low as 1ms, could cause
huge jitter, like timing between packets ranging between 1 and 400ms
instead of 10-30ms.
So its only worth changing that value if you are going to do real
loopback testing to see if you can get stable results.
