OLED ostentationem interface et imperium experimentum report

background

OLED (organicum diode-levis emittens) ostentationes late in variis electronicis machinis adhibitae sunt ob earum altam rationi discrepantiam, vim humilem consummationem et tempus velox responsionis. Hoc experimentum destinatur ad ostentationem OLED interfaciendam et moderandum microcontroller utens. Usus exactoris ostentationis SSD1306 est, quae communis usus est pro tegumentis parvis OLED.

Hardware components

  1. OLED ostentationem: moduli ostentus usus ab SSD1306 moderatoris acti.
  2. Microcontroller: Utere an 8051 microcontroller-substructio ad ostentationem OLED regendam.
  3. potentia copia: A 3.3V vel 5V copia virtutis OLED moduli requiritur.
  4. Connectens linea: coniungere OLED cum microcontroller.

Circuitus nexum

  • GND: coniungo ad virtutem humum.
  • VCC: coniungere ad 3.3V vel 5V copiam virtutis.
  • D0 (SCL): coniunge P1^4 (SCL).
  • D1 (SDA): coniunge P1^3 (SDA).
  • RES: coniungere ad P12.
  • DC: coniungere P11.
  • CS: coniungere P10.
