Question
Chapter 13, Problem 5P
Program Plan Intro
Voltage test:
- When the controller operates in RUN mode and the LED status indicator does not illuminate even when the input device is activated, then the voltage test must be performed to predict the error.
- For this purpose, voltage level must be measured across the input terminals.
- If the current voltage level is obtained, then the input module must be changed.
- If the voltage level is not correct, then there might be a possibility of fault in power supply, wiring, or input device.

- Is there a way to determine whether a program is interfering with a device's output? Having more people utilize the system at once might degrade its stability and performance.arrow_forwardA circuit has two pushbutton switches connected to pin PA2 and PA3 and two LEDs connected to pin PC0 and PC1 of the AVR ATmega16 microcontroller. Write a program to control the LEDs as follows; blink PC0 LED if the PA2 pushbutton is pressed with 2 seconds total delay time for every blink and blink PC1 LED if the PA3 pushbutton is pressed with 300ms total delay time for every blink.arrow_forwardHow exactly does the basic input–output system (BIOS) function?

Use Timer0 to create the 1.0 second delay and Timer1 to create the 0.5 second delay. Be sure to use the MPLAB simulator to verify the proper operation of the program. Once you have fully debugged the program, write the code to the PIC-P40 and demonstrate its operation to the instructor by uploading a video to YouTube (see note below).arrow_forward
- How many of the computer's parts, including internal and external, get power straight from the wall outlet? .arrow_forwardSuppose that you are designing a game system that responds to players’ pressing buttons and toggling joysticks. The prototype system is failing to react in time to these input events, causing noticeable annoyance to the gamers. You have calculated that you need to improve overall system performance by 50%. This is to say that the entire system needs to be 50% faster than it is now. You know that these I/O events account for 75% of the system workload. You figure that a new I/O interface card should do the trick. If the system’s existing I/O card runs at 10kHz (pulses per second), what is the speed of the I/O card that you need to order from the supplier?arrow_forwardWhat precisely do you mean when you talk about the "quick Launch Tray" in relation to the "system tray"?arrow_forward

Counting between 255-0 with 50 ms intervals in reverse, the number is displayed on the top line during the counting process. and the bottom line shows "Stop->Press RA2" and the system is restarted when the button is pressed. Write the program that returns it to state (solve with ccs)arrow_forwardYou are met by the whirling sound of the fans located within the system when you turn on your computer.unit. However, you noticed that the noise wasn't as loud as it had been when you turned on the computer.In addition, the fan at the back of the system unit was not functioning.
