Witam!
Zmęczony częstym zaglądaniem do clouda w kompie albo na telefonie w celu kontroli temperatur i napięcia na akumulatorach skleciłem program, który wyświetla na wyświetlaczu TFT - ST7735 jednocześnie 8 wartości z różnych DS-ów zamontowanych w domu.

Kolejność jest następująca:

- odpalamy swojego clouda i robimy linki bezpośrednie (read) z DS-ów, które nas interesują i zapisujemy je,
- czyścimy wemosa,
- wgrywamy przy ustawieniach DOUT i 32Mbit lub kompilujemy źródło i wgrywamy przez arduino,
- resetujemy wemosa i podłączamy się do wifi " Dir_8_TFT",
- wypełniamy tabelkę configu (na opisy DS-ów mamy po 15 znaków)
- zapisujemy i czekamy aż komp wróci sam do swojego wifi,
- w cloudzie nic się nie pojawia, a dane wyświetlają się na wyświetlaczu
- pierwsza wartość wyświetli się po upływie około 15 - 20 sek (czyli odświeżanie trwa około 2,5 minuty),
- chcesz dokonać zmiany to zwierając na 15 sek D1 do masy wchodzimy ponownie do configu i dopisujemy jeszcze raz swoje wifi, hasło do niego i zmieniamy co tam chcemy.

I to FINAŁ. Możemy cieszyć się nowym gadżetem.

Bardzo fajny pomysł tyle opcji w jednym wyświetlaczu mamy podgląd co się dzieje w naszym domu. Gratuluję pomysłu i wykonania. Mam prawie, że identyczny wyświetlacz muszę spróbować u siebie czy pójdzie. Brawo!

Temperatury wyświetlają się w cloudzie tam, gdzie są podłączone DS-y a urządzenie "scalające" wyświetlanie na TFT to dodatkowe urządzenie nie pojawiające się w cloudzie.

Tak. Będzie pasował. Jest na 3v3 i model ten sam co u mnie ST7735. Pozdrawiam

Złożyłem sobie narazie na stole układzik. I mam pytanie czy jest możliwość rozjaśnienie wyświetlacza bo słabo widać. Trzeba się przybliżyć aby coś zobaczyć.

A podłączyłeś BL do +3V3? Możesz dać fotkę?
