easy🧠 Conceptual Q2 of 15
Raspberry Pi - SPI Communication
Which Raspberry Pi pins are typically used for SPI communication with a display module?
AGPIO 17 (Input), GPIO 27 (Output), GPIO 22 (PWM), GPIO 10 (MISO)
BGPIO 2 (SDA), GPIO 3 (SCL), GPIO 4 (CE1), GPIO 5 (MOSI)
CGPIO 14 (TX), GPIO 15 (RX), GPIO 18 (PWM), GPIO 23 (CE0)
DGPIO 10 (MOSI), GPIO 9 (MISO), GPIO 11 (SCLK), GPIO 8 (CE0)
Step-by-Step Solution
Solution:

  1. Step 1: Recall SPI pin functions on Raspberry Pi

    SPI uses MOSI (Master Out Slave In), MISO (Master In Slave Out), SCLK (Clock), and CE (Chip Enable) pins.

  2. Step 2: Match pins to functions

    GPIO 10 is MOSI, GPIO 9 is MISO, GPIO 11 is SCLK, and GPIO 8 is CE0, which are standard SPI pins.

  3. Final Answer:

    GPIO 10 (MOSI), GPIO 9 (MISO), GPIO 11 (SCLK), GPIO 8 (CE0) -> Option D

  4. Quick Check:

    SPI pins = GPIO 10, 9, 11, 8 [OK]
Quick Trick: SPI uses MOSI, MISO, SCLK, and CE pins on Raspberry Pi [OK]
Common Mistakes:
MISTAKES
  • Confusing I2C pins with SPI pins
  • Using wrong GPIO numbers
  • Mixing UART pins with SPI
