add option to disable decimal point and digit pin #3

Closed I-hate-2FA closed 4 months ago

I-hate-2FA commented 4 months ago

i am using single digit 7 segment display with just 8 connection without decimal point, and single digit does not need digit pin for multiplex, it can be connected directly to 3v3, since 7 segment display without shift register is already such a waste of pins, i want to save these 2 for other use, i hope you can add option to ommit it

btw using gpio38 will cause kernel panic

asergunov commented 4 months ago

Sounds awesome. It's easy to implement making pin optional or maybe esphome has some fake pin. Feel free to implement. I'll help in PR even if will not work right away.

asergunov commented 4 months ago

btw using gpio38 will cause kernel panic

That's strange. I have it in use: 

esphome:
  name: furnace
  platformio_options: 
    board_build.f_cpu: '240000000L'

esp32:
  board: esp32-s2-saola-1
  framework:
    type: arduino

external_components:
  - source: "github://asergunov/7segment_gpio"
    refresh: 0s

display:
- platform: 7segment_gpio
  id: lcd
  digit_pins: [1,2,6,4]
  iterate_digits: false
  segment_pins:
    - 21 # g
    - 40 # f
    - 14 # e
    - 10 # d
    - 36 # c
    - 17 # b
    - 34 # a
    - 8  # .
  colon_pin: 38
  degree_pin: 13
  update_interval: 1s

Maybe framework or board is different? Or ESPHome version. I'm using 2024.5.5. Which is yours?

Edit: looks like you are using ESP32

asergunov commented 4 months ago

Looks good? https://github.com/asergunov/7segment_gpio/pull/5

I-hate-2FA commented 4 months ago

yes i am using original esp32, gpio34-38 hardware does not allow output, i just thought it as good way to disable that output, but it didnt work

idk how to make external component, as you can see i am still relying on custom sensor which technically is depricated

I-hate-2FA commented 4 months ago

i am using version 2024.6.4

asergunov commented 4 months ago

Yup. You need another pins.

I-hate-2FA commented 4 months ago

so latest version allow to use these pin as placeholder now? because there is breaking bug in esphome now, everytime i want to compile i need uninstall and reinstall esphome addon https://github.com/esphome/issues/issues/5998 it is very hard to test things

asergunov commented 4 months ago

@I-hate-2FA I've made code changes but not tested. Could please let me know if it works? https://github.com/asergunov/7segment_gpio/pull/6

Just remove or comment out your digit_pins

asergunov commented 4 months ago

reinstall esphome addon

I'm using the local install. Hardest part is to create venv

python -m venv `.venv`

and activate it

What OS you are using? On Linux it will be

source ./.venv/bin/activate

Then just install esphome

pip install esphome

and you are ready to go

I-hate-2FA commented 4 months ago

i am using windows on my pc, and home assistant os on server if i can acess inside container, i can probably just delete the old build file manually, but because home assistant os is lock down i cannot, so install esphome on pc is a option

I-hate-2FA commented 4 months ago

Just remove or comment out your digit_pins

how can i update the external component to latest

asergunov commented 4 months ago

You can find how activate venv on windows here

asergunov commented 4 months ago 
external_components:
  - source: "github://asergunov/7segment_gpio@one-digit-support"
    refresh: 0s

Just add branch name and make sure refresh is 0s so it will pull repo every build

asergunov commented 4 months ago

For the dot I can't see any limitations in code. Looks like it should work if you specify just 7 segment pins.

i tried that the first time, but i didnt look closely at the error so i thought it wont work

I-hate-2FA commented 4 months ago

seems to work with current config:

display:
- platform: 7segment_gpio
  id: sevenseg
  segment_pins: 
    - number: 4
      inverted: True
    - number: 16
      inverted: True 
    - number: 17
      inverted: True
    - number: 5
      inverted: True
    - number: 18
      inverted: True
    - number: 23
      inverted: True
    - number: 19
      inverted: True
  update_interval: 100ms
  lambda: |-
    if(id(keepon).state){
      if((millis()%2000) < 500){
        it.printf(0,"O");
      }else if((millis()%2000) < 1000){
        it.printf(0,"P");
      }else if((millis()%2000) < 1500){
        it.printf(0,"E");
      }else{
        it.printf(0,"n");
      } 
    }else if(id(ledr).state){
      it.printf(0,"%d",id(timer));
    }else{  
      it.printf(0,"H");
    }

thanks allot! it is very helpful project

asergunov commented 4 months ago

Awesome. I've merged PR and removed branch. Please remove @one-digit-support to make it work

asergunov commented 4 months ago

For pin inversion I've opened #8 . Feel free to implement. Doesn't look hard

Thanks for sharing. Feels good! Thanks for contribution!

asergunov commented 4 months ago

Look at that. I've spotted a bug. That's why it was not stop on generation stage https://github.com/asergunov/7segment_gpio/pull/9

Could please check if it work so I could merge it?

asergunov commented 4 months ago

Thanks! Looks like everything is resolved here. Can we close it?
