Seven-way answer buzzer

Overview

Function Description:
This system uses seven digital tubes to display the scores of seven contestants, one digital tube to display the contestant who successfully answered, and two digital tubes for the countdown timer.
Seven buttons simulate seven contestants. A 74LS373 latch chip and a 74LS148 encoder chip are used to detect who answered first.

A revolution in benchtop power supply testing
Power has been integral to electrical engineering since the days of Edison and Tesla, so much so that there was a time when designers took it for granted that it was the last task in the design proces

Is it necessary to switch modes when nesting arm interrupts?
I see that in arm's irq interrupt handler, the scene is protected in the assembly code, and then the cpsr is modified to clear the I_bit, and then the IRQ mode is switched to the sys mode, and then th
I need help with the setting of external resistor voltage divider for 4152 LCD.
Moderator and all the masters:I am using 4152 chip. Now, in order to reduce power consumption, I use external resistor voltage divider to drive LCD. I have tried 750K, 680K, and 470K resistors respect
[Ask TI] The C280X series found that after the GPIO port configuration is initialized, it will automatically become a low level
I recently did PWM and accidentally found that the PWM output is high level by default when powered on, but after initializing the GPIO port configuration (setting the pull-up resistor and the GPIO po
Register Control of LMX2592
I use TI's LMX2592 chip to generate a 5G clock signal, and use FPGA to control its registers using the SPI method. The hardware is designed by myself, and the power supply of the chip is measured to b
