Re: pyb.USB_VCP() performance?

Thanks!

I guess that with 9600, I am short.

On PC side, I simply run:

Code: Select all

import serial
ser = serial.Serial('COM5', 9600)
while True:
    nb = ser.in_waiting
    if nb > 0:
        buf = ser.read(nb)
        print buf
I will upgrade to 115200, that should help.

Re: pyb.USB_VCP() performance?

Hi,

Would it be more efficient to use pyb.UART?
Actually, I will have to use a RS232/USB adapter, but why not!

Any idea?

pyb.USB_VCP() performance?

Hi, I run into a small performance issue. I read an encoder and send a torque value (DAC) to a DC motor. My control loop runs at 200Hz, using a Timer. Everything works well, except when I try to send some data to the PC. I use USB_VCP u = pyb.USB_VCP() And write to the PC at 100Hz (another Timer) wi...

Re: Slow read?

Perfect!
It works well, thanks.
For Windows users, a VM is pretty nice actually (for those who failed installing cygwin!)

Re: Slow read?

Great, your screen command worked !

Then, rshell too: sudo rshell -p /dev/ttyACM0 -b 115200

Re: Slow read?

Did someone had rshell working in an Ubuntu on VirtualBox (on a Windows 7 PC) ?
Just tried it but no success.

I see /dev/ttyACM0
but rshell nor screen /dev/ttyACM0 worked.
They are both installed of course.

It keeps running, looking for something, maybe. But no message untill I ctrl+C it..

Re: Slow read?

Thanks!

Actually, on Windows, rshell does not seem to work.
Get an error at "import readline"

Another way to never corrupt files?

About performances, is there something to activate, or deactivate?

Re: Slow read?

<<accessing filesystem from "domains" is bad>>
I guess pyboard is only reading main.py
But does it mean that I should not edit the main.py on the board, directly ?
