raspberry pi pico not powering up spi tft display
April 2, 2024, 14:56
dosnt work or turn on when i connect my pico to power. also vs code dosnt detect my library
im completely new to raspberry technology
import machine
import st7789
spi = machine.SPI(0, baudrate=24000000, sck=machine.Pin(18), mosi=machine.Pin(19))
display = st7789.ST7789(spi, 240, 240, reset=machine.Pin(20), dc=machine.Pin(16))
display.fill(st7789.color565(255, 0, 0))
display.text("Hello, World!", 60, 120, st7789.WHITE)
display.show()
code.
dosnt import st7789
ImportError: no module named 'st7789'
pip installed it didnt do anything.
Are you sure you have connected the display correctly?
There are 2 cables leading from the display to the +
Is that really how it should be?
?
2 cables to the power yeah.
both the vcc and the led need 3.3 volts
i did ask the chat gpt person to make me an example code as i just wanna know that its working
because i want to sandpaper the sd card part
SD card? Do you have a link to the display?
link?
I want to trim this a bit
but still the screen dosnt work either way
Product description Link?
I don't know exactly what kind of display you're using...
tft spi
And now you want me to look for what you bought?
of course not sir.
i bought this.
no touch
Please read https://discord.com/channels/818384379197784084/1189386838788542464 as it is now the code is unreadable
idk how to bold
<@796000224690307072> did i do it right?
Kind of, there is a lot of blank lines, but the formatting is perfect. Thx
Mark the text and press "Ctrl + B" for bold
ah
thank u
anyways i need help with this.
if anyone can help
1. The link to what you bought look like a display with a driver chip ILI9341 or ILI9488, so why are you using st7789?
2. The picture of the wiring is just a rats nest for me... A drawing is better.
3. What IDE are you using for programming?
4. I would advice you to search for a tutorial how to get starting.
5. A second advice start with something simpler than the display as your first project.
And there is also some get started here https://discord.com/channels/818384379197784084/1194546099575341117
using a pico W
i already got everything set up on the pico
its using a different driver chip?
damn.
wiring:
vcc is connected to 3.3V
Well It could be as you haven't stated which display you have?
Check the specification
And I stand by my advice.
.
There you have the ddriver IC
Ill try to use that driver but.
My problem is that the screen dosnt even turn on
Im pretty sure when these types of screens get power they immediately power on
Showing a white screen
Talked to the seller..
Told me arduino only.
My biggest problem right now is that i bought this screen to connect a micro hdmi to it
Or mini hdmi
So i can use it on the zero.
Raspberry pi zero
That display has a SPI interface and that is a generic interface that can be used with any computer/micro controller.
Arduino, Pico, STM32, PC.
https://en.wikipedia.org/wiki/Serial_Peripheral_Interface
There are drivers/libraries for Arduino C, different flavours of Python and probably other languages as well. So the seller doesn't know what they are talking about.
And HDMI ? Then your in for a hard ride.
Ah thanks. I bought a screen specifically for the raspberry zero because of that..
Bc he told me that
But if we get this to work then ill probably refund it
But the thing is that it just dosnt work regardless
Seems tho im not getting any help but. Ill wait.
