Raspberry Pi - Display and Output

ARead sensor data, update image buffer, then call disp.image() and disp.display() in a timed loop.

BContinuously call disp.clear() without updating image buffer.

CUpdate OLED display only once at program start.

DChange I2C address each time sensor data updates.

Step-by-Step Solution

Solution:

Step 1: Efficient update strategy
Reading sensor data and updating the display buffer regularly keeps info current.
Step 2: Use timed loop for smooth updates
Looping with disp.image() and disp.display() updates OLED with new data efficiently.
Final Answer:
Read sensor data, update image buffer, then call disp.image() and disp.display() in a timed loop. -> Option A
Quick Check:
Timed loop with buffer update = efficient display refresh [OK]

Quick Trick: Update display inside sensor read loop [OK]
