As people in industrial and agricultural production have higher and higher requirements for speed regulation, AC motor variable frequency speed regulation technology is increasingly used in production...
Have you ever played with fax chips? During fax communication, the sender needs to send TCF. Is it a string of "0"s for 1.5s or 0x00 for 1.5s? In addition, how does the receiver determine whether the ...
I made a new board and I drew the circuit diagram according to the LMH6624 data sheet. The simulation shows that it can amplify 10dB, but the actual measurement shows that the gain is 0dB below 1MHz, ...
It was working fine when I burned the program a few days ago, but today when I burned the old LED, the delay was obviously much slower. Did you use ISP to download the program? Please help. . . ....
