tides's Issues

Work on graphics

Custom dithering

See here /pimoroni/pimoroni-pico/issues/681 and /pimoroni/pimoroni-pico/issues/745

Not quite possibl yet to just load into the framebuffer.

Might be worth trying to evaluate if there's another way, like downloading the images as pngs then reading pixel by pixel and using picographics. Not sure if there's enough memory for that though

Add firmware to the repo

make copy of inky frame launcher, with tides in it

make it auto refresh once an hour

Skip the node stuff and rewite all using picographics

Output multiple images in advance

output images for the next 24 hours with filenames

Make data refetching smarter

Since tides,sea level and astronomical data don't change, they can be fetched in advance only once a week or so, and we can use more of the 10 request quota to get more frequent weather updates

Add more weather visualisations

• air temp recommended clothing
• cloud cover
• rain drops
• wave height
• wind direction
• wind sock

Rewrite firmware in C++ for faster display updates

Use available colours

In the ts node script:

• generate the image with canvas

• use rgbquant to dither it

  • render to png for debugging

• save to a custom file format

  • raw binary buffer
  • use similar/same structure to what goes into the buffer
    • maybe same but a single 3b plane instead of 3 1b planes
      • so it can be read bit by bit if needed

In the micropython firmware:

• load buffer into memory
  • or read bit by bit?
• set the pixels one by one

Optimize if needed by:

• defining a background colour
  • set that first to the whole screen
  • then only setting pixels that aren't the background colour
• setting pixel spans instead of individual pixels

Get data from stormglass API

• store api key in github secret
• cache the data in github cache
• add workflow input to force refresh twice a day, at 7am and 2pm

3D model the frame
