Whаt did Frаnklin Rооsevelt's first Fireside Chаt fоcus on?
Use yоur оwn mаteriаls tо do the following: For this prаctical, you will design a memory‑mapped 8‑bit output port for the µPAD using the data memory space and the EBI system within the ATxmega128A1U, a 82 ms timer, and utilize PortA pin 0 (PA[0]) as an input. Attach the OOTB Switch & LED Backpack for this practical. Additionally, you will [1] connect LED circuits to bits 7 through 0 of the created output port (OUT[7:0]), [2] create a continuous 164 +/-15ms periodic waveform (~82 ms low and ~82 ms high), [3] use Out[7] to output the continuous 164 ms periodic waveform, [4] only if PA[0] is one, use Out[0] to output the 164 ms periodic waveform. When PA[0] is zero set Out[0] to 0. Physically construct a memory-mapped 8-bit output port to be accessible only via the 8,192 (8k) consecutive data memory addresses starting at 0x9000. Utilize a subset of the following: a breadboard, a 74HC573 8-bit 3-state transparent latch, a 74HC574 8-bit 3-state D flip-flop, a programmable logic device (PLD), a dual-inline package (DIP) switch bank, a DIP LED bank, relevant resistor packages, the relevant OOTB components, as well as anything else appropriate. Write an assembly program to appropriately configure the EBI system for the above-mentioned context, to continually output the periodic waveform on Out[7]; also output the periodic waveform on Out[0] whenever PA[0] is true (Vcc). Note that CS0 is not available, since it is utilized by the SRAM on the OOTB Memory Base. Utilize a watch window to continuously display the register that you use to write to the output port. Add to the watch window so that it also continuously displays the value of PortA (PA[7:0]). To sufficiently demonstrate (for this practical) that the output port is enabled only for the relevant address range, before utilizing the input to determine whether to output the waveform on Out[0], write different values to the output port using four different memory locations. These four memory locations (use this ordering) are [1] the address immediately before the start of the range (0x8FFF), [2] the first address within the relevant memory range (0x9000), and [3] the last address within the range, and [4] the address immediately following the end of the range. Put a breakpoint before the first write and following each of the four write instructions. Following the last write, complete the program requirements (using the last address within the range). You are expected to demonstrate the following to a PI or Dr. Schwartz, in the same order provided: The relevant physically constructed hardware, including all logic designed with the PLD. The relevant program, code executing as specified, utilizing software breakpoints to demonstrate where the relevant chip select base address(es) are configured, where the relevant chip select size(s) are configured, and where the specified memory addresses are written to (placing a breakpoint before the first write and then following each of the four write instructions). A watch window should display the register that you use to write to the output port and also the PortA values. Use your Waveforms and the appropriate function of your DAD to display both Out[0] and Out[7]. Also display the precise period of Out[7] using the appropriate Waveforms function. When you are finished or five minutes before the end of this practical (whichever comes first), you must zip your Microchip/Atmel Studio project along with your Quartus project and upload the resulting zip file here. Failure to upload your zip file before the end of the practical will result in a grade of zero. When you have finished your upload, use chat to let the PI know by sending READY.
This questiоn verifies thаt yоur webcаm is pоsitioned аt the correct distance from your workspace and at the correct angle. Your face, both hands, the computer screen, keyboard, mouse, and everything else that will be used during the actual test must be visible throughout the entire test. If this requirement is not met, your test must be be graded as zero according to the proctoring requirements. Does the camera setup that you see on your computer screen match the image below? If not, please correct it now and maintain the same view throughout the entire exam.
This questiоn checks whether yоur cоmputer’s volume is loud enough for the test.Some questions will аsk you to reаd аloud, and your professor must be able to hear you clearly. If your voice cannot be heard, in case of the real test, the entire test must be be graded as zero according to the proctoring requirements Please increase the volume above the normal level if you haven't already done so.When you are ready, read this question aloud and select "True".
