Actually, I have never thought about writing such an article. Maybe I am not a person who likes to meddle in other people's business. As long as I handle my own affairs well, it will be OK. However, s...
This problem has been bothering me for a while. Please give me some advice. To describe it in words: initialize the program in the main function, first initialize the timer Timer0, set it to a 2ms tim...
How is the OTP chip programmed after SMD? How is it programmed during testing? How is it programmed during mass production? It is different from MCU. MCU has a dedicated interface, but this chip does ...
I saw the introduction of JDT-698H simulator on the Internet, and it seems to be very powerful. Their online sales also said that the storage capacity of the simulator's logic analyzer is unlimited! I...
What shall I talk about next?
Last time I wrote about the generation of two frequency waves in FSK. Now let’s talk about how to transmit the signal through the antenna.
The voltage amplitude Vpp of th...
TIOBE released the programming language rankings for April 2012. The biggest highlight of this ranking is that C has pushed Java off the throne and returned to the top. Based on the growth rates of th...
