Orange PI

[betolley]

I managed to get Raspberry Noaa to run on a orange pi One running the latest Armbian.

Several of the dependencies don't exist and I had to compile then or install them by hand because they had a different name. But it is now working.

I edited the requirements and depenancy files to remove what i had to install by hand.

Meteor works. what would case this with noaa?

Could you share what you had to install / change by hand for other people who might want to do this? Merging #108 is the first step on the path to supporting more platforms for this.

Nice to see a new HW!

The noaa issues look a bit like an audio sample rate issue…. As @Cadair suggests lets understand if you had to do anything custom on install, and also as always with all support issues, sharing logs helps avoid the guess work!

[betolley]

How do I fix the audio sample rate? I downloaded the file and ran through noaaapt and it was viewable. I need to to work on wxtoimg. I read the slat correction and it didn't really do anything unless I did it wrong.

Click on Options, Disable PLL
Next, Click on Image, then Slant correction
Draw a line alone one of those groups of similarly-colored pixels left to right.
Accept the sample rate it shows, making sure to set only NOAA sampling frequency
Click Options, (un check) Disable PLL

Here is how I installed it:
I created a user called pi then
I used the directions and up to here it was the same:

Then I updated ~/raspberry-noaa-v2/ansible/roles/common/tasks/dependencies.yml

- name: install dependencies
  become: yes
  apt:
    update_cache: yes

    deb: https://github.com/wkhtmltopdf/packaging/releases/download/0.12.6-1/wkhtmltox_0.12.6-1.raspberrypi.buster_armhf.deb
    state: present

Then i installed predict by hand from the predict website. I had to alter it so that there was a link in /usr/bin for predict

Then I

sudo apt-get install libjpeg9-dev
sudo apt-get install libjpeg62-turbo-dev libjpeg62-turbo

But wasn't sure if that was enough so I also downloaded jpegsr6.zip

wget https://versaweb.dl.sourceforge.net/project/libjpeg/libjpeg/6b/jpegsr6.zi

and compiled and installed it.

Then I manually installed these

sudo pip3 install setuptools
sudo pip3 install pyyaml
sudo pip3 install jsonschema
sudo apt-get install python3-ephem
sudo apt-get install python-numpy
sudo apt-get install python-matplotlib
sudo apt-get install python-pillow
sudo apt-get install python-pyyaml
sudo apt-get install python3-pyyaml
sudo apt-get install python3-pillow
sudo apt-get install python-yaml
sudo apt-get install python-yaml
sudo apt-get install python-ephem
sudo apt-get install python-idna
sudo apt-get install python-jsonschema
sudo apt-get install python-yaml
sudo apt-get install python-requests

And edited the requirements file to this:

#ephem==3.7.7.1
#idna==2.10
#jsonschema==3.2.0
#matplotlib==3.3.4
#numpy==1.19.5
#Pillow==8.1.2
#pyyaml==5.3.1
#requests==2.25.1

Then I ran
./install_and_upgrade.sh

I had to give up on the orange pi one with it. The orange pi one usb 2 was working at USB1 speed. I ended up buying a HP G1 Chromebox and changed the os to armbian and followed the same steps as above and it is working great now

Sample rates are set in (for example)

raspberry-noaa-v2/scripts/audio_processors/noaa_record_rtl_fm.sh

Line 46 in 2cd1fd0

timeout "${CAPTURE_TIME}" $RTL_FM -d ${SDR_DEVICE_ID} ${BIAS_TEE} -f "${freq}"M -p "${FREQ_OFFSET}" -s 60k -E wav -E deemp -F 9 - | $SOX -t raw -e signed -c 1 -b 16 -r 60000 - "${OUT_FILE}" rate 11025

The capture of the source is 60k and the sox transcode to wav is 11025 etc.
