Raspberry Pi Test 1 UPDATED ACTUAL Exam Questions and
CORRECT Answers
interpreted language - python
Max amount of GPIO pins - 15 (250mA)
Wiring mode - Broadcom (BCM)
For loop in Python - "for i in range"; identifies things in a list and puts them together in a loop
Setup - (pin#, GPIO.OUT)
analog to digital converter - MCP3008 (10 bits)
Nyquists Sampling theorum - should at least sample 2x the highest frequency component
duty cycle - Ton/Period
Sampling Rate - 960 KHz (636)
Default clock division - 256
Quantization or Sample Resolution - The number of digital representations or bits that are used
to represent the voltage at the point of time when the analog signal is sampled.
one clock cycle - one bit sent, one bit recieved
