CEIS114 Module 4 Lesson 3 – programming concepts, lesson review, and revision
material
Typically, in an embedded system, the microcontroller's _____ is burned with a purpose for
specific functions needed for the system. - correct answer ✔✔ROM
The problem with interfacing a CPU board to an external device is that the input and output
ports are typically _____ and the external device is often analog. - correct answer ✔✔digital
Match the appropriate word to the letter in the sentence.
Small _____(A)_____ motors can also require hundreds of milliamps. _____(B)_____ motors
often require high _____(C)_____ pulses to operate. Furthermore, remember that motors and
_____(D)_____ are made with coils of wire, which therefore are inductors. They will generate
large _____(E)_____ pulses when the currents are shut off. - correct answer ✔✔DC
Stepper
current
relays
voltage
Most microcontrollers have a few _____ of bytes of EEPROM memory, which is enough to store
relatively complicated programs downloaded from a PC. - correct answer ✔✔thousands
Most microcontrollers can handle only a small amount of current directly through the I/O pins
(typically 20-25 mA), which is enough to light up an LED. However for circuits that need more
