I have found a bug in MQTT software. When I subscrive to a topic, the python code creates the subscription at the beggining of the setup code, before it connects to wifi and mqtt.

Here is the sample:
def setup():
global page0, label0, LTemp, label1, temperatura, slider0, button0, off, mqtt_client, wlan, rotary
mqtt_client.subscribe('termostato/temperatura', mqtt_termostato_temperatura_event, qos=0)

M5.begin()
m5ui.init()
page0 = m5ui.M5Page(bg_c=0xffffff)
label0 = m5ui.M5Label("Umbral", x=30, y=81, text_c=0x85231b, bg_c=0x302c2c, bg_opa=0, font=lv.font_montserrat_24, parent=page0)
LTemp = m5ui.M5Label("Temperatura:", x=41, y=39, text_c=0x000000, bg_c=0xffffff, bg_opa=0, font=lv.font_montserrat_14, parent=page0)
label1 = m5ui.M5Label("19,0", x=152, y=81, text_c=0x85231b, bg_c=0xffffff, bg_opa=0, font=lv.font_montserrat_24, parent=page0)
temperatura = m5ui.M5Label("00.00", x=141, y=39, text_c=0x000000, bg_c=0xffffff, bg_opa=0, font=lv.font_montserrat_14, parent=page0)
slider0 = m5ui.M5Slider(x=38, y=119, w=160, h=22, mode=lv.slider.MODE.NORMAL, min_value=190, max_value=290, value=210, bg_c=0x115e9f, color=0x2c90e4, parent=page0)
button0 = m5ui.M5Button(text="Set", x=54, y=172, bg_c=0x2196f3, text_c=0xffffff, font=lv.font_montserrat_14, parent=page0)
off = m5ui.M5Button(text="OFF", x=124, y=171, bg_c=0xf36021, text_c=0xffffff, font=lv.font_montserrat_14, parent=page0)

off.add_event_cb(off_event_handler, lv.EVENT.ALL, None)
BtnA.setCallback(type=BtnA.CB_TYPE.WAS_CLICKED, cb=btnA_wasClicked_event)
slider0.add_event_cb(slider0_event_handler, lv.EVENT.ALL, None)
button0.add_event_cb(button0_event_handler, lv.EVENT.ALL, None)

page0.screen_load()
wlan = network.WLAN(network.STA_IF)
rotary = Rotary()
wlan.connect('bencab', 'arrabal6')
rotary.set_rotary_value(19)
mqtt_client = MQTTClient('m5termostato', '192.168.1.34', port=1883, user='user', password='pass', keepalive=33149)
label1.set_text(str((slider0.get_value()) / 10))

A calculator that can be programmed in python, and with a symbolic math engine is not as usual. Nspite from Texas Instrument, HP Prime, and Casio CP-400 ... mine can do things these other can`t (wifi connect). But there is a reason, commercial companies are looking for a tool in class, mine is only for fun :-D

frequency modulator .... I will investigate and see what can I do
Thanks

I have developed a graphics calculator with a symbolic math engine, using esp32 and a custom PCB, but I have a few M5 stack devices and I have migrated the software ... it runs great. Quicker than my custom PCB :-D
A link to the project.

I have updated to this version my core2 with faces keyboard, and the led are bright at 100%. I have not been able to stop them.

@cepics said in ATOM LITE + OLED Unit 1.3" 128 × 64 Display:

static constexpr const char* text[] = { text0, text1, text2, text3, text4, text5, text6, text7 };

I don´t like it ... please remove it and give a try in the loop with a static string ...

And also, put any serial.println() debug code to see what code are you running

why is it not working? Any error code? it is difficult to help you if you give no information.

Hello, I have developed a small program, and I store some strings in Spanish ... so some strings have UTF8 char. For instance 'salmón' --> b'salm\xc3\xb3n' ...
When I put the variable in the label ... I write 'salmn' :-(
Any ideas??

it is .... thanks

Hello I have a new friend and it looks good, but I have a small problem.
I can use USB UIFlow without problems, but when I switch to wifi (web IDE) it shows a message error:
">>> Wait COM.X module connect and stable :) [TX:14 RX:13]"
">>> Wait module stable timeout. Please check module connect :("
But I have no module connected, and I think I have configured wifi ok.
I have checked from RLPT and I can connect to wifi.

I send an image ...
