I use Teensy 3.6 on Arduino 1.8.13, Teensyduino 1.53, Ubuntu 18.04 when I stream data from Serial port Teensy freeze
mycode.ino
output
49-teensy.rules
hope somone help me , Thank you
mycode.ino
#include <DHT.h>
#define DHTPIN 24
#define DHTTYPE DHT22 // DHT 22 (AM2302)
DHT dht(DHTPIN, DHTTYPE);
void setup() {
Serial.begin(9600);
dht.begin();
}
void loop() {
float h = dht.readHumidity();
float t = dht.readTemperature();
Serial.println(t);
Serial.println(h);
delay(1000);
}
output

# UDEV Rules for Teensy boards, http://www.pjrc.com/teensy/

# The latest version of this file may be found at:
# http://www.pjrc.com/teensy/49-teensy.rules
#
# This file must be placed at:
#
# /etc/udev/rules.d/49-teensy.rules (preferred location)
# or
# /lib/udev/rules.d/49-teensy.rules (req'd on some broken systems)
#
# To install, type this command in a terminal:
# sudo cp 49-teensy.rules /etc/udev/rules.d/49-teensy.rules

# After this file is installed, physically unplug and reconnect Teensy.

# If you share your linux system with other users, or just don't like the

# ModemManager tends to interfere with USB Serial devices like Teensy.
# Problems manifest as the Arduino Serial Monitor missing some incoming
# data, and "Unable to open /dev/ttyACM0 for reboot request" when
# uploading. If you experience these problems, disable or remove
# ModemManager from your system. If you must use a modem, perhaps
# try disabling the "MM_FILTER_RULE_TTY_ACM_INTERFACE" ModemManager
# rule. Changing ModemManager's filter policy from "strict" to "default"
# may also help. But if you don't use a modem, completely removing
# the troublesome ModemManager is the most effective solution.
