easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall spidev usage
spidev requires creating an SpiDev object first, then calling open(bus, device).Step 2: Check syntax correctness
spi = spidev.SpiDev(); spi.open(0, 0) correctly creates spi = spidev.SpiDev() then calls spi.open(0, 0).Final Answer:
spi = spidev.SpiDev(); spi.open(0, 0) -> Option AQuick Check:
spidev object then open() method [OK]
Quick Trick: Create SpiDev object before calling open() [OK]
Common Mistakes:
MISTAKES- Calling spidev.open() directly without object
- Using wrong bus or device numbers
- Using incorrect method syntax
