Monbit Weekend progress

It's quite interesting that I managed to fully work on Monbit after exactly 1 month (still shame on me -_-)
I've managed to fully switch to the new board ESP32-S3
The biggest struggle was to actualy upload it (I could not connect to it, I had to hold the boot button, then connect the USB and then upload FW) and of course cable management
I've connected all the peripherals and it works (so far).
Lastly, I have connected the battery but I would like to implement a small circuit that would allow me to read the battery level.

Tag filtering

I think it's time for a new version release - v1.0.5
After playing with the image resizing, I have decided to add tag filtering for FieldNotes
You just click on a tag that you want to see and you should see all FieldNotes that have that tag.
It's not major feature and I would like to add View All option so you don't have to reload the field notes.

Somtehing like icon

During the weekend I have decided to try and 'draw' an icon.
I was hoping to make something nice and simple.
The result is not the best, I am not good and pixelart lol. It'S just a purple planet-like object, or blob.
I might change it in a future but it will do for now.
Also, now you can click on an image to expand it. Click again and it will go back to the default position.

Final touches for less glitches

I have finished the last bit that was causing the glitching - project details.
Now everything is build at the beginning and Nginx points to the 'dist' folder where is a new html generated with all it's necessary stuff.
I am still unsure if that is the best approach. I might eventually need to use some kind of framework. However for now, it works well.
The styling of the header and footer has been improved (I hope).
I have also added a dropdown menu for projects and icons to projects (curently same for all of them. I would like to create my own in the future.
I made a small space between the different logs/projects/cards and editet style to Field Notes so it's almost the same but different, also the date has been moved to the right.

Introducing NodeJS cuz the glitching was devastating.

I re-did, re-wrote and re-designed a few things.
I spent an hour deciding which font to use, I am still unsure about the current one.
There should not be any glitches anymore. (noticed only few within selected projects)
The NodeJS had to step in and it builds the web before it's being accesible.
Majority of the parts are now loaded upon building the website so it should not affect the visual aspects. ^.^
Still need to fix few things, but it's a progress!
Oh and as my dear friend suggested, the '#' should be clickable so user can filter based on them.
Actually I am thinking of adding a filtering system based on date, project type, hasthags etc.

Field notes have arrived

New version with field notes arrived.
The Field Notes are basically random notes that does not have any place but I just want to have theme here.

Heading nightmare

I finally got some time to do more things with this project.
Then I realised I don't so I managed the h1 sizes at least.
Still thinking about the style that I want to go with.
I need to draw icons as well!
But thats it for now, I have finals in few days so I need to focus on that first.

It still works, yay!

New ESP board struggle

It has been some time since I last worked on this project, but the new ESP finally arrived!
I tried switching to the new ESP32-S3 Super Mini board, but what a pain that was!
After about 3 hours of debugging, arguing with ChatGPT, and almost losing my mind, I ended up creating a custom configuration for this board since none of the available ESP32-S3 configs in PlatformIO were working.
The best part is that it works! Or at least I can see the === MONBIT === log.
The question is whether it's going to work with all the peripherals connected, but that's a TODO for now.

New menu entry

Added a new menu entry, Info, which displays more information about the monster itself: Name, Species and Status.
The status is currently None because the monster is alive and healthy. I don't want to show short-term status there, only long-term ones.
In the future I want to add an option to reset the monster.
I also increased the sleep and entertainment gain because it was too low.

monbit

v0.0.6

Added basic monster logic; the monster has different states and moods.
States: None, Playing, Eating, Sleeping, Dizzy, Sick, Injured, Dead.
Moods: Happy, Normal, Hungry, Tired, Bored, Sad, Critical.
It still needs testing. Not all states are implemented yet; for example, Dizzy logic will be added when the accelerometer is added.

Menu system update

Added a more polished menu system and made the code more readable and organized.
Settings are still mock, but I will implement them later. The user should be able to turn off the sound and change the monster name.
Next focus is monster logic.

v0.0.5

I decided to switch to a new ESP32 module, the ESP32-S3, mostly because of the extra GPIO pins I will need for the accelerometer.
Currently waiting for the module to arrive (approx. 2 weeks).

Audio update

Finally managed to implement clear sound with a specific configuration.
The problem was not the hardware but the audio config; wiring can stay as it is.
You can hear one beep sound when you power the device.

v0.0.4 - Audio System

Soldered speaker to MAX98357A amplifier.
Wired amplifier to ESP32-C3.
Created audio module (audio.hpp and audio.cpp).
The speaker produces buzz instead of a clear tone and I have no idea why; maybe the I2S config is wrong.

v0.0.3

Added flash storage system
It was quite easy actually, so I am happy about that.
Saving is performed after a button is pressed.
I would also like to add an autosave every 5 minutes.

Button functions

The button now feeds the monster by 10 until hunger is back to 0.

v0.0.2

First button connected to pin 0
GUI refreshment
Renamed happiness to fun so in GUI it is displayed as F instead of a second H

First button

First button input succeeded!
And don't forget: BUTTONS HAVE ORIENTATION!
Then I connected the display as well and added a function which refreshes the display.
When I click the button, the screen refreshes.

New GUI

I updated the GUI to look a bit cleaner and polished. Obviously, it is not final yet.
I also had to rename happiness to fun so there are not two H values displayed; it was quite confusing.
I am considering changing it later to something like HUN, ENG, FUN, AGE or just using icons.

Three buttons connected

Connected two more buttons and added them on pins 8, 9 and 10.
The old Feed button was removed, and currently the code only prints which button was pressed: LEFT, MIDDLE or RIGHT.
The breadboard is a mess, I know, but it will eventually be better.
Left button feeds the monster: hunger decreases by 10.
Middle button plays with the monster: fun increases by 10, hunger increases by 10, and energy decreases by 5.
Right button makes the monster sleep: fun decreases by 5, hunger increases by 5, and energy increases by 10.
