Is the principle of USB programming the same as that of ordinary serial communication? I used a serial modem to program a short message receiving and sending system. Now after changing to a USB modem,...
Recently I am using PIC microcontroller to simply control 1602.
1. The chip is 16f877a, and the configuration word is __CONFIG(0x1832); //Chip configuration word
2. External reset circuit, add a butto...
This program uses ADC0809 to collect the voltage output from RW2 and displays it on a seven-segment display. Now I want to write the displayed data to SBUF and send it to a PC. I have tried many times...
When an AC voltage is applied to a capacitor, the capacitor should have a charging and discharging process, and the voltage across the two ends should not change suddenly. This is also the principle o...
[color=rgb(34, 34, 34)][font="]To understand the amplification effect of transistors, we can use a very common object in life as an analogy. Let's take the NPN transistor as an example. The PNP transi...
