Have you tried looking at windows settings to make sure that they are correct?
Control Panel > Device Manager > Ports (COM & LPT) > COM20 , Right click, Properties, Port Settings tab,
Bits per second:115200
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

Thanks Leif, I did do the update, it always downloads the same 4 files.

Thanks Douglas but I am still a newbie so I don't know where that file lives.

@György-Farkas said in newbie issue with gpioctl not seeing HIGH on Arduino Dock 2:

ATmega chip

That worked, thank you.
However I have an OLED on the expansion header so I would prefer to use the ATmega pins because that is why I bought the Arduino Dock 2 board.

I think I found the direction to flash the ATmega pins, however I don't see a sketch to program it with, or documentation on what commands to use to control those pins.

I am using Omega 2+
I am using Arduino Dock 2
I am using pin 7 on what they call micro-controller header, pin 7 which is the pin set near the DC barrel jack
https://docs.onion.io/omega2-docs/arduino-dock-2.html

root@Omega-EFEB:/# gpioctl clear 7
Using gpio pin 7.
root@Omega-EFEB:/# gpioctl dirout 7
Using gpio pin 7.
root@Omega-EFEB:/# gpioctl dirout-high 7
Using gpio pin 7.
root@Omega-EFEB:/# gpioctl get 7
Using gpio pin 7.
Pin 7 is HIGH

However, when I measure the voltage on pin 7 I get 0v and I was expecting 3.3v, what am I doing wrong?

I am trying to read from a DHT22 using Python and the easiest example that I can find. I would think reading from a gpio pin should only be 4 lines of code, but I cannot find that.

What I have done is get Python 2.7
I downloaded Adafruit_Python_DHT from
[https://github.com/adafruit/Adafruit_Python_DHT]

However, I get stuck at their command

• sudo apt-get install build-essential python-dev

root@Omega-EFEB:/# sudo opkg install build-essential python-dev
Unknown package 'build-essential'.
Unknown package 'python-dev'.
Collected errors:

• opkg_install_cmd: Cannot install package build-essential.
• opkg_install_cmd: Cannot install package python-dev.

What do I need to do to get this to work?
Thanks.
