trying to let my 1x8 and 4x8 segement turn fully on
December 20, 2023, 18:42
the segements both have some parts on but not all
Here, by the way, because of the display, apparently you can't control it properly without the circuit board.
https://raspberrypi.stackexchange.com/questions/28934/how-to-connect-7-segment-4-digits-display-with-pi
but shouldn t all lights turn on atleast
cuz now 2 do on the 4x8 but not very bright
I don't know about this but this was mentioned and also marked solution:
" There is no simple solution to a raw display like you linked.
That requires multiplexing, which requires constant processing to
to maintain the display. Maybe with a threaded library you could
something acceptable, but I don't know if such a thing exists.
As an alternative, you could use the Adafruit LCD display with I2C interface. Adafruit has a tutorial for using it with the Raspberry Pi and has a Python library on github that seems to be what you want.
There is even sample code."
but shouldn t the hardware just work without it?
Just want this on the 1x8 and 4x8
I have no idea but the text from the link, if you would read it, tells me that things are going very badly. And as I already mentioned, I don't really have a clue, but I am of the opinion that it doesn't work or only works very badly without the circuit board.
yeah but you need code to show a diff number i get that on 4x8 but it needs to shine in the first place and it doesn t
Can you get the display working without Raspberry Pi. Connect a-g to + via resistors (value?) and d1 to GND or vice versa depending on what display you have (common andode or cathode).
And start by adding info about your circuit, schema, URL your following, components your using.
Got this now
im using a rotary a 1x8 and a4x8 and wanna add buzzer led and button latrer
Got this now the rest of the pins are directed to the 1x8 on the same line as the other a etc
Can also try kicad but doesn t seem user friendly 😅
If you first read and then answer perhaps something meaningfull appears!
idc anymore hopeless anyway
No, you just have to read properly and answer the questions completely and not just halfway. In the Python Discord too, someone asks you about the products you use so that they can help better, but you don't answer.
And remember all people that try to help you do it voluntarily, no one is forces, paid or coerced in other ways to help you.
it is been here for 4 days now
Please post info that can be used to help you!
All other stuff you post isn't helping you!
no peogression anyways
So you are telling me you don't need any help?
just saying i have asked a lot of help but little to no progress in 4 days
And now I try to help you and ....?
py
from RPi import GPIO
from time import sleep
clk = 16
dt = 20
GPIO.setmode(GPIO.BCM)
GPIO.setup(clk, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
GPIO.setup(dt, GPIO.IN, pull_up_down=GPIO.PUD_DOWN)
counter = 0
clkLastState = GPIO.input(clk)
try:
while True:
clkState = GPIO.input(clk)
dtState = GPIO.input(dt)
if clkState != clkLastState:
if dtState != clkState:
counter += 1
else:
counter -= 1
print (counter)
clkLastState = clkState
sleep(0.01)
finally:
GPIO.cleanup()
this is the code rotary
py #importeer GPIO en time package import RPi.GPIO as GPIO import time #gebruik BCM mode voor de pin nummering (conform breakout) GPIO.setmode(GPIO.BCM) #zet de pin als input GPIO.setup(4, GPIO.IN) # loop through 20 times for i in range(20): print(GPIO.input(4)) time.sleep(1) GPIO.cleanup()
and this of the button
And the you have figured out issue with the LEDs?
no started off from scratch
Sp have this now
Wanna make a game where you scroll the number with scrollthing it will beep when you get close and harder when ur on it you press the scrollthing and it will add to the number when you get 1 it will add to the 4 numbers so you guessed 18 18.. 1815 and if all are guessed led will glow and will show a code on it after x amount of time.sleep()
How should i place it on my gpio for a logicol structure also needs to start without screen so with a button
A recommendation, ask one question and when that is completed take the next question.
And when you get into trouble use the KISS principle https://en.wikipedia.org/wiki/KISS_principle
As you have done now, get the rotary coder to work first
so it needs to switchg lef and right need to set cap wich should be pretty easy and something with a press like in my other code
Yes, but add print statement so you can verify the code
As you have done in the button code
i print the counter
?
And when you post pictures, crop away unnecessary stuff!
Post like this
Ooops I cropped away the button
alr
The rotary code is exactly as a example I have used before from PiHut
And to verify it there is a print counter as you said.
Have you check that code?
yeah
And ?
the result?
-1 0 to infinite but alr knew that
But I didn't
And what is "arl" ?
And now I start to wonder, why do I use a lot of time to help you? Please have a rethink! And Im off to bed.
