Raspberry Pi Pico 1.54inch LCD Pinouts for screen and buttons

2024-07-29 06:27:32 Ask

I'm trying to run some code designed for the Picosytem which uses the same screen.  I've edited it in Thonny and attempted to run it but get no output, leading me to believe I have the wrong pinout and specifically this line:

class ST7789(framebuf.FrameBuffer):

   def __init__(self, width=240, height=240, id_=0, sck=10, mosi=11,

                dc=8, rst=12, cs=9, bl=7, baudrate=62500000):

is horribly wrong, but that's what I get after reading the example code.

Could we get a pin = screen pin/button diagram for this kit?

If anyone else is looking for this info here's a timesaver:


self.__up = Pin(16, Pin.IN, Pin.PULL_UP)

       self.__down = Pin(14, Pin.IN, Pin.PULL_UP)

       self.__left = Pin(13, Pin.IN, Pin.PULL_UP)

       self.__right = Pin(17, Pin.IN, Pin.PULL_UP)

       self.__button_A = Pin(3, Pin.IN, Pin.PULL_UP)

       self.__button_B = Pin(6, Pin.IN, Pin.PULL_UP)

       ### self.__buzzer = PWM(Pin(15))  ###no buzzer

       super().__init__(width=240, height=240, id_=1, sck=10, mosi=11,

                        dc=8, rst=12, cs=9, bl=13, baudrate=62500000)

It sounds like you're having pinout issues with your Pico and ST7789 display. A diagram would definitely help! By the way, have you tried the dummies world cup game? It's a fun way to practice coding while enjoying the tournament! Good luck!
