Hi Adafruit tech support,
I have a metro express M0 running circuitpython version 7.3.3
I installed adafruit-circuitpython-metro_m0_express-en_US-7.3.3.uf2
I updated the libraries using the lib bundle adafruit-circuitpython-bundle-7.x-mpy-20221107.zip
I am getting the following error
Traceback (most recent call last):
File "main.py", line 42, in <module>
AttributeError: 'module' object has no attribute 'Servo'
here's the code in main.py
# Servo on D5
servo = simpleio.Servo(board.D5)
Can some please provide some assistance with this issue
Thank you.

Re: Metro express M0
You want to use Adafruit_Motor now not simpleio.
You will need to copy over the library and import it in the code.py
This guide will help.

Re: Metro express M0
thank you for the reply much appreciated.
Actually I am trying to the main.py working. this was included after I installed the 7.3.3
it would be nice to have the sample code that came with the Adafruit Metro M0 express.
thank you

Re: Metro express M0
The sample code I provided above is what you would populate a main.py file with to control a stepper.
I’m not sure what the exact sample code that is currently shipping on the Metro M0 Express. My guess would be a basic blink example like this:

Code: Select all
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}
