У меня есть raspbery pi pico (китайский клон с 3 кнопками и цветным светодиодом). Я использую Thony и microphyton. Дисплей st7735 80x160. Как вывести на него текст или хоть что нибудь? Chatgpt помог мне помигать цветным светодиодом, вывести температуру в консоль, но с дисплеем ничего не получается. Прошу помогите.
Забиваете в гугль название контроллера и тип дисплея и ищите.
Скорее всего точно такого как надо скетче не будет - значит придется комбинировать з двух-трех, а может и пяти.
Понятно, что для этого надо что-то понимать в программировании. Причем самому, а не через ЧатГПТ

Я бы не обращался на форум без предварительного поиска в гугле. Я так понимаю основная проблема в том что не установлена нужная библиотека. Я пробовал через Manage packages установить, ошибка. Я пробовал закидывать в папку lib файлы с githab, не работает. Сейчас я смотрю видос на индийском и пытаюсь разобраться в элементарной задачи. С chatgpt я делал гораздо сложнее вещи с обычным пайтоном.
По крайней мере ошибку не выдает, что радует. Но на дисплее ничего нету
ну дак ему и пиши.

Так я ему и писал не однократно, дисплей так и не заработал в Thony выдает ошибку.
По ссылке было про ChatGPT и лингвистические модели. Вкратце он НЕ решает технические задачи. Он строит ответ так, чтобы это было максимально похоже на техническое решение задачи. Иногда это может работать, но далеко не всегда. При должном понимании, иногда достаточно небольшого редактирования чтобы заработало, а иногда это просто бред на заданную тему.

Я понимаю, я его упомянул только по тому что он нормально работал с обычным пайтоном, в этой ситуации он не смог помочь
Для пайтона больше примеров в сети, больше откуда можно надергать работающего кода.
Спасибо конечно за пояснение, но проблему это не решает. Я не требую ничего, я обращаюсь к тем у кого есть желание помочь. Конечно я не думал что мне придётся обратиться за помощью форума в такой базовой вещи.
номера пинов поправил?
Честно пытался понять где в коде номера пинов, так и не разобрался
6 и 7 строка
Тогда, может, следует начинать с чтения учебников?
Похоже, Вы обратились не по адресу.
Здесь помогают только тем, кто сам что-то делает.
У Вас есть еще вариант обратится в платный раздел форума “Ищу исполнителя”.
Чат ГоПоТа и программирование, это как гопота на улице !!!
Что бы что то заработало надо правильно подключить и в скетче правильно указать что и куда вы подключили.
Из спича ТС я понял только что он заливает что то в плату pico, а дисплей, лежащий в коробочке в соседней комнате, ничего не отображает …
Вывод на дисплей начинается после первой секунды и в Wokwi не нашел чистого st7735 - по этому использовал ili9341 (протокол у них идентичный, а вот размер другой = вывод не на весь экран и с ориентацией беда - разбираться не стал) …

Перекинул на raspberry pi pico st7735 и в корень и в папку lib.
Пытаюсь вывести на дисплей текст кодом:
import machine
from machine import Pin, SPI
import st7735
# Установите соответствующие пины для подключения дисплея
scl = Pin(2)
sda = Pin(3)
res = Pin(12)
dc = Pin(13)
cs = Pin(14)
blk = Pin(15)
# Инициализация SPI
spi = SPI(0, baudrate=20000000, polarity=0, phase=0, sck=scl, mosi=sda, miso=None)
# Инициализация дисплея
display = st7735.ST7735(spi, res=res, dc=dc, cs=cs, backlight=blk)
# Инициализация дисплея
display.init()
# Установка цвета фона и переднего плана
display.fill(st7735.BLACK)
display.text('Hello', 10, 10, st7735.WHITE, sysfont)
# Отображение текста на дисплее
display.show()
Выдает ошибку:
MPY: soft reboot
Traceback (most recent call last):
File "<stdin>", line 17, in
AttributeError: ‘module’ object has no attribute ‘ST7735’
В 17 строке разберитесь что не так может ST7735 надо изменить на st7735…или как там в модуле прописано …
