I got it!!

Sorry, the trouble was very simple!... If you want, the solution is below:

Prova_basica_1:

Prova_basica_2

Hello there,

I've almost arrived at my goal!

I've almost arrived at my goal! But; I don't know how I should continue. I will send you two files. They're created with Uiflow 2.0. The first version, named Prova_basica_1 is absolutely functional, and the second one, named Prova_basica_2, is my nightmare!

The trouble finds in the conversion from ASCII code to character, I can't do it

Please, may you aid me?

Thank you, and excuse me for the inconveniences.

Best regards!

P.S. In this message I send you two images from UiFlow 2.0 program and I've just attached below the code from two programs

Code Prova_basica_1:

import os, sys, io
import M5
from M5 import *
from unit import CardKBUnit
from hardware import I2C
from hardware import Pin

label0 = None
i2c0 = None
cardkb_0 = None

text = None

def cardkb_0_pressed_event(kb):
global label0, i2c0, cardkb_0, text
text = cardkb_0.get_string()
M5.Lcd.printf(text)

def setup():
global label0, i2c0, cardkb_0, text

M5.begin()
Widgets.fillScreen(0x222222)
label0 = Widgets.Label("label0", 105, 143, 1.0, 0xffffff, 0x222222, Widgets.FONTS.DejaVu18)

i2c0 = I2C(0, scl=Pin(33), sda=Pin(32), freq=100000)
cardkb_0 = CardKBUnit(i2c0)
cardkb_0.set_callback(cardkb_0_pressed_event)
Widgets.fillScreen(0xffffff)
M5.Lcd.startWrite()
M5.Lcd.setCursor(10, 40)
M5.Lcd.setTextSize(2)
M5.Lcd.print('>>', 0x000000)

def loop():
global label0, i2c0, cardkb_0, text
M5.update()
cardkb_0.tick()

if name == 'main':
try:
setup()
while True:
loop()
except (Exception, KeyboardInterrupt) as e:
try:
from utility import print_error_msg
print_error_msg(e)

Hello,

There is a few days ago, I wrote a similar trouble. My message was…

Hello,

I didn't think that I could feel so interested about this system! Sorry for my questions about, because I'm very unexpert.

I'm math teacher in secondary in Spain, and I want to prepare a trigonometric practice very simple.

I've used a potenciometer (angle unit), PaHUB, PbHUB, 8servos unit, and two servos: one 360º limited, and another one, 360º unlimited. Until this moment, all was right. But, I've done some little changes, I wasn't conscient that, when I erased the PaHUB unit, and I added another one, some address changed. I reviewed all the program, and I think that it should run. But, I don't know why now, when my program is running, at the end of compilation, it appears this message "E (112496) i2c: i2c driver install error".

Thank you for your attention

Please, does someone aid me?

Thank you for my poor English. Best regards!
