Si un nou ceas, doar cu Wemos D1... Inspiratie si sursa aici :   Doar am facut mici modificari (mesaje in engleza, fonturi partial modificate). Astept activarea API pentru da

Te-am întrebat pentru că mă interesează o librărie pentru folosirea versiunii i2c a acelui afișaj, pentru a o putea folosi în alte medii de programare. Pentru cel cu SPI mi-am făcut o mică librărie prin extragerea din librăria Arduino. Pentru cel cu i2c nu am reușit încă.

Știu despre existența acelor librării, sunt foarte stufoase și eu nu sunt familiarizat cu arduino ide.

Pentru SPI eu mi-am extras într-un fișier pe post de librărie doar câteva funcții ce am folosit la un proiect.

Important e să am funcțiile de init_lcd, cls, set_xy și un print_char. Eventuale alte funcții le pot dezvolta ulterior.

Postez ce mi-am făcut eu pentru versiunea SPI (digit5x7 și digit40 sunt tabele cu fonturi), ceva de genu ăsta mi-aș dori pentru afișajul cu i2c: 

/* Functii pentru folosirea displayului OLED de 0,96" cu controler SSD1306 de 128/64 pixeli,
   organizat ca 8 rînduri/pagini cu inaltimea de 8 pixeli si 128 coloane. Deci la pozitionarea cursorului
   pe verticala, axa y, nu avem 64 da valori posibile ci 8 (randul 0,1,2,3,4,5,6 si 7)
*/

Am incercat o varianta de ceas de pe blogul Nicu FLORICA (niq_ro) dupa schema de mai jos si am urmatoarea eroare de care nu pot trece. In arhiva sunt mai multe variante a acestui ceas si la toate este aceiasi eroare.

Intr-un final m-am prins cum sta treaba. Fisierle FontLEDClock1 si FontLEDClock nu trebuiesc declarate impreuna. Chiar daca in .ino apar declarete ambele trebuie sters unul dintre ele.

In varianta 1.3 de cand introduce senzorul de temperatura/umiditate nu functioneaza. Apare doar un Hello! , clock ver 1.3 (3 este afisat invers).

Functioneaza corect varianta 1 si 1.2. Deja la varianta 1.2 apar ceva probleme in sensul ca se initializeaza greu.
