I'd like to read in the output of a voltcraft vc960 voltmeter
connected to a usb-port.
I found the perl-script below but I'd like to accomplish the same with
python:
I guess I have to use the module serial but I don't know how I should
set the serial parameters so they are the same as in the perl-script.
Could someone supply me the command for setting the serial-parameters
correctly
in Python?
thanks
Jean
#!/usr/bin/perl
use strict;
use warnings;
use Device::SerialPort;
die("Usage: $0 /dev/ttyS0\n") unless $#ARGV == 0;
my ($devicepath) = @ARGV;
my $port = new Device::SerialPort($devicepath);
die "Couldn't open serial port" if ! defined $port;
$port->baudrate(2400);
$port->databits(8);
$port->parity("none");
$port->stopbits(1);
$port->handshake("none");
$port->rts_active(0);
$port->dtr_active(1);
#$port->read_char_time(5); # wait 5ms per character
$port->read_const_time(200); # 0.2 second per unfulfilled "read"
call
$| = 1; # autoflush STDOUT
while(1) {
my ($nin, $in) = $port->read(255);
print $in;
}
$port->close;
