@vlad2005 era un pdf de la phillips parca, despre Snubber networks. Discutia de acolo era despre snubber pentru triace, dar ceva ceva tot se potriveste si in acest caz. Acolo sunt date niste formule de calcul, deci nu e totul empiric. In alta ordine de idei, am si eu o problema asemanatoare,a sa am dat peste acest topic. Am un modul de comanda cu ESP32 care imi comanda niste relee si un motor DC printr-un driver TA6586 (e un modul selector de intrari audio si control volum - cu potentiometru cu motor; am o postare despre asta, in alta sectiune). Ambele module (cel cu ESP si driver) sunt alimentate din aceeasi sursa de 5V. Problema este ca ESP se reseteaza cand ii dau comanda de Vol up sau Vol down (adica este pornit motorul intr-un sens sau altul). Am pus un cond de 470uF pe alimentarea TA6586 dar se pare ca nu rezolva problema. Voi incerca cu 100nF pe pinul de reset, cum a spus @ratza. Si o alta chestie ciudata: am alimentat ambele module dintr-o sursa step-up chinezeasca, reglata la 5V pe iesire; cand am dat comanda vol up, motorul a functionat pt scurt timp, afisajul sursei s-a stins si a mirosit a ars. Modulul cu ESP prezenta scurt pe alimentare. Un coleg a descoperit ca se strapunsese cond-ul smd de pe intrarea regulatorului AMS1117 de pe placuta ESP. Deci cumva, am avut o supratensiune acolo (probabil caderea de tensiune cauzata de pornirea motorului a facut ca sursa sa mareasca tensiunea de iesire pentru a compensa scaderea tensiunii). In fine, problema principala cred ca e resetarea MCU si voi incerca varianta lui @ratza si revin. In orice caz, in montajul final probabil voi folosi un regulator liniar, dar tot va fi probalema cu resetul.

Mulțumesc frumos!

@cloudy îmi pare rău, dar nu știu unde ar trebui să inserez codul tau, imi da eroare la compilare. Poti pune, te rog, tot sketch-ul? ca sigur eu am inserat aiurea ce ai postat tu. Multumesc!

Mi-am dat seama ca trebuie sa testez montajul complet, cu tot cu encoder, desi nu cred ca a suferit modificari codul pe partea de encoder. O altă chestie este un flicker al LED-urilor,atunci cand tin apasat butonul pe telecomanda. Banuiesc ca flicker-ul se poate diminua modificand valoarea wait_loops, nu? Ar trebui micsorata sau marita?

Șiii...câștigător este primul cod din arhiva lui @cristi7521!! Încă nu am testat varianta propusă de @cloudy. Trebuie să înlocuiesc în sketch ce a postat el, îmi va lua ceva timp sa fac asta, ca tare imi e ca uit vreo paranteza ceva sau lipesc aiurea. Dar îl voi incerca si pe acela în curand si anunt aici daca merge sau nu. În orice caz, mulțumesc mult pentru ajutor. Atașez codul funcțional. Îl voi mai testa zilele astea si daca am timp testez și cu integratul de control al motorului potentiometrului de volum, ca a fie treaba treabă. /* Muffsy Relay Input Selector * * Control relays using IR and rotary encoder * Control external power to amp using IR and push button * LM3886 * * Last update with functionality changes: 2023-09-27 * * Introduction: * The software works on the concept of "powerState", which determines the behavior of the Input Selector: * * 0: Boot * Read last input channel from NVRAM, selecting the same input as when the input selector was turned off or lost power * The input selector is muted, and mute LED is turned off * Print startup message * powerState is changed to 2 (off) * 2: Power OFF * Turn off all relays * Set power amp to off (SSR = LOW) * The input selector is muted, and mute LED is turned off * Limited functionality, only IR powerbutton and rotary encoder pushbutton is active * All input events, even those not available, will be shown in the serial monitor * * 1: Power ON * Turn on power button LED * Set power amp to on, SSR = HIGH * Activates the input channel read from NVRAM * Will start muted with mute LED turned on * No actions are read until the input selector unmutes after 1500 ms (default) * All functions available, IR Remote and rotary encoder * All input events and actions will be shown in the serial monitor */ /* * Load libraries */ #include <EEPROM.h> // EEPROM Library #include <IRremote.h> // IR Remote Library #include <Versatile_RotaryEncoder.h> // Rotary Encoder Library /* * Startup delay * * When powering on, the input selector is muted to avoid any unwanted pops * Set the delay value in milliseconds (default 1500) * * Change to 0 for no delay */ #define startupDelay 1500 /* * Enable SSR * * If you want to use a Solid State Relay to control mains power to an * amplifier or similar, set this value to 1 * * Default 0 (disabled), as handling mains power is dangerous */ #define enableSSR 1 /* Mute and Power on / off: * * The rotary encoder is also a push button, which registers * either a short or a long press.

am testat continutul celui de-al doilea fisier de la @cristi7521. partea de schimbat canale functioneaza normal, partea de volum, nu: daca apas vup, led-ul (ca pt testare folosesc led-uri pe pinii pt ctrl volum) de vup ramane aprins chiar si dupa ce a incetat apasarea tastei. La fel se intampla si pt vdwn, totusi cand se stinge un led celalalt se stinge (exista insa un timp cand cele 2 leduri sunt simultan aprinse, ceea ce este rău pentru puntea H ce va fi comandată!). Ledurile pot fi stinse apoi doar cu power off, in rest, ramane unul aprins. Ma pun sa incerc si primul fisier.

da, butoanele de la 0-9 au acele valori. La fel si butoanele power, mute, chanel up si dwn, vol up si dwn. de celelalte nu am nevoie, asa ca nici nu le-am mai verificat. ESP trimite pe serial ce tasta s-a apasat la telecomanda, asa le-am dibuit. Folosesc o telecomanda universala pe care am programat-o sa dea coduri pt daewoo cred, ca nu am nimic daewoo prin casa. Am incercat si alte coduri IR, dar unele erau din 2 secvente, de exemplu pentru tasta 1 imi trimite 22 si 15. Am incercat pana am gasit un cod IR care sa fie din cel mult 2 cifre si sa nu interfereze cu ce am prin casa.

L-am intrebat pe Bing dar nu ma inteleg cu el. Cred ca nu stiu eu sa-l intreb.

Salutare! Sunt si eu interesat de acest subiect, ba chiar de proiectul colegului @Untold pe care-l rog sa incarce sketch-ul final, functional, daca se poate. Multumesc!

E posibil ca Nano sa nu poate gestiona treaba cu ecranul (poate procesor prsa slab, prea puțin RAM, mai ales la o clona). Citisem pe undeva ca sunt probleme la combinatia asta de nano cu ecran (grafic) oled. Incearca cu un ESP32, poate e mai potent. E doar o parere...

de testat, testez eu cand am timp. Numai sa nu patesc cum am patit si in cealalta postare: programatorul s-a lasat pagubas.

multumesc pentru raspuns, dar oare ar fi bine sa modificam codul si sa o luam de la capat cu incercarile? Am mai incercat acum ceva ani sa fac un astfel de selector si cu control volum si am ajuns la concluzia ca mai bine il fac pe acesta. Codul e deja scris, mai e de bibilit puțin la el. Cred ca acel bRecRepeat nu e pus unde trebuie....dar nu ma pricep L.E.: codul nu-mi apartine, e facut de nordicul ala. Eu doar am incercat sa-l adaptez

Am revenit. am compilat sketch-ul, nicio problemă. L-am încărcat și testat: power on si apoi power off, la vreo 2 secunde, în buclă. Nu mai primeste nicio comanda, probabil pentru ca nu mai are timp sa primeasca si comenzi. Nu stiu unde sa modific, probabil e prins in bucla ceva ce nu ar trebui sa fie acolo.
