In the figure, 74LS373 is an 8d latch with thre

A) Yes, start to wait for release B) No, return 0 and exit (4) latency of 5 ms, jitter Elimination (5) confirm, return the press signal, and exit Of course, in the single-chip microcomputer, you can also cyclically count to confirm whether it is pressed. Bingo believes that this is a waste of MCU resources, so it will not be said again. 3. De-jitter of buttons in FPGA Many textbooks have not discussed the dejitters in FPGA. But Bingo think

When the MCU clock speed is switched to 32 kHz, IAR can download the Code but cannot debug it. the following error occurs. It indicates that the IAR cannot establish a connection with the target MCU. The specific cause is that the communication speed of SWD is much higher than the MCU clock speed, which leads to communication failure. IAR can be debugged in t

It may be a coincidence that this is not explicitly stated in the official chip manual. With a rigorous scientific attitude, we do not use this unofficially confirmed feature to develop our programs. Program reliability is very important, which should be paid attention.Imagine if you use a single-chip micro
