    Some set of parameters, and already work the two loops without interference. #include"M5Stack.h" int mensaje=0; int mensaje1; QueueHandle_t queue_1; void loop_tarea1(void * pvParameters); void setup(){ M5.begin(); // inicio del M5s queue_1 = xQueueCreate(1, sizeof(int)); if( queue_1 == 0 ) { m5.Lcd.setTextSize(2); m5.Lcd.print("no creada la lista");} xTaskCreatePinnedToCore(loop_tarea1, "Tarea1",1500, NULL, 1, NULL,0); } void loop_tarea1(void * pvParameters) { for( ;; ) { if (xQueueReceive(queue_1, &mensaje1, ( TickType_t ) 10) ) { m5.Lcd.setTextSize(5); m5.Lcd.setCursor(150,0); m5.Lcd.print(mensaje1);} } } void loop() { mensaje=0; if (Serial.available()){ mensaje=Serial.read(); xQueueSendToFront(queue_1, &mensaje, ( TickType_t ) 10); } delay(10); }

    @crami25 Thank you very much for this information. I have improved with the capacitor, without changing the potentiometer (I only have that at hand). I'm using the range adjustment at 1.5 v ( ADC_2_5db) and making analogSetSamples(16) , I get this dispersión that would be by 0.2%. It's all right. I'll keep testing, Greetings.

    Thank you very much for your answers help me understand this hardware. Yes, that's my question. Use M5stack regulator to power the M5Stack and not from charger . In this case and, it is a last question about this, there will be no problems with the USB input if it is powered by an external battery. In some other case I have had problems connecting the USB, because both 5v sometimes are not exactly and that small difference produced power noises by connecting the USB, and sometimes reestorting the unit. Best regards

    @brus Use the M5Stack with the makey 16-channel capacitive touch unit ! I've made a banana touch keyboard using the M5Stack and the makey hub as shown with the original Arduino-MakeyMakey in https://www.youtube.com/watch?v=pfjWdoW7pt4 . You can program the makey banana keyboard using blockly. good luck crami25

    @lukasmaximus Sure, I can try, was never good in making guides but could be an intetesting expierence for me aswell Will try to move my project on micropython with help of your guide, as said time is our enemy :] I also want to add new feature, right now my html form looks like Name:input field I want to add current values label to html form, so when I open html I can see current value sent to it by esp32 (M5Stack in our case) It actually a good project which gives a lot of knowledge with tcp/ip, html, css (and even javascript), C, micropython, basic electronics. I would recommend to make something similar for everyone who is starting to explore IoT and embedded things

    Hi, did you solve this? Sounds like a scope, or casting issue. I'm having a different problem with the IMU and I can see you have a IMU class with Gyro, Accel and Mag data incorporated. Is it for the MPU6886 + BMM150 sensors. Would you be happy to let me have a look at : IMU class .h & .cpp files. MahonyAHRS.h & .cpp files. I'm fighting with the MahonyAHRSUpdate I'm using. The calculations are diverging to NaN after just 2-3 calls and I'd like to compare your code to mine. Thanks!
