Teensy 4.1 trouble getting started

[spyork]

Turns out I cant even get the simplest LED program to run. A career in embedded systems and software development didnt help me.

Left the pin at 13 for the teensy 4.1. Here is the versions and sample code.

Arduino 1.8.13
Teensyduino 1.53
Windows 10 platform

I bought a USB cable with the teensy so that I would have all the right pins. I am using a motherboard USB port and not a powered USB hub, not sure if that matters.

When I first hooked up the teensy 4.1, the LED was blinking. Then I tried to download and run the LED program. No blinking...

I have read thru the troubleshooting pages and didn't find any solutions.

LED Code:

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.

This example code is in the public domain.
*/

// Pin 13 has an LED connected on most Arduino boards.
// Pin 11 has the LED on Teensy 2.0
// Pin 6 has the LED on Teensy++ 2.0
// Pin 13 has the LED on Teensy 3.0
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {
// initialize the digital pin as an output.
pinMode(led, OUTPUT);
}

// the loop routine runs over and over again forever:
void loop() {
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(led, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

Make sure your USB cable is not just a "charging cable". see https://www.pjrc.com/teensy/troubleshoot.html

[KurtE]

Also note: when a teensy ships the code is setup that it does not have USB type of serial, so will not respond to Serial reboots..

So for new boards, I will typically use a simple blink program. Use the Arduino blink program,

Then click the verify button, which should then compile and load up the teensy program...

Then I press the program button on the Teensy. It should hopefully see the teensy show it program the chip, and then a new Serial port should be assigned by windows to the board... (Hopefully)

Yeah, see above, I bought the cable with the teensy because I read about this problem.

Thanks,

OK, I will try this today. Thanks for the help.
