Trinket Pro 5V programming problems

[CodyThatWilson]

Hi all,

I am working through https://learn.adafruit.com/guardian-rob ... w/software and I'm using the pro 5V controller.

I can't seem to get it to program, no matter what I do. I have a newer laptop, and it would not connect - so I moved to two other computers with the same issue. I noticed that there is a warning about USB2.0, so I then used an older computer that is a friends. However, I'm getting this issue now that I can't find a solution for:

Code: Select all

Sketch uses 924 bytes (3%) of program storage space. Maximum is 28672 bytes.
Global variables use 9 bytes of dynamic memory.
avrdude: Expected signature for ATmega328P is 1E 95 0F
         Double check chip, or use -F to override this check.
Wrong microcontroller found.  Did you select the right board from the Tools > Board menu?

I have it set to

Code: Select all

Pro Trinket 5V/16MHz USB
USBtinyISP
port dev/ttyS4 (happened automatically?, doesn't do anything if I change it to S0 or move the USB input)

The trinket is flashing red, and I can press the trinket button (to get to bootloader) and immediatly press the upload on the arduino blink code and the red light will stop blinking when it spits out the error message. Here's what happens when it's not in bootloader mode (so I know it can at least see something):

Code: Select all

avrdude: error: usbtiny_transmit: Input/output error
avrdude: initialization failed, rc=-1
         Double check connections and try again, or use -F to override
         this check.


avrdude: error: usbtiny_transmit: Input/output error
avrdude: error: usbtiny_transmit: Input/output error

Thoughts? I've been working on this project for days now, and I'm pretty stumped.

Here is the blink code, it verifys just fine (it's the example)

Code: Select all

/*
  Blink

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

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:

  This example code is in the public domain.

*/

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
}

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

I enabled more output if this helps -
