easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Recall Python serial library usage
The correct method to open a serial port is using serial.Serial() with device and baud rate as arguments.Step 2: Check each option's method name
Only serial.Serial() is valid; others like open(), connect(), start() do not exist in pyserial.Final Answer:
serial.Serial('/dev/ttyS0', 9600) -> Option CQuick Check:
Use serial.Serial() to open UART [OK]
Quick Trick: Use serial.Serial() to open UART port [OK]
Common Mistakes:
MISTAKES- Using non-existent methods like open() or connect()
- Forgetting to specify baud rate
- Using wrong device path
