The previous article introduced how the clocks of the Central and Peripheral in a piconet are synchronized, as well as the time slots (hereafter referred to as slots). Now, we will discuss how to transmit and receive.1. Transmit/Receive TimingIn a piconet, the Central always starts transmitting on even slots (i.e., when CLK1=0), while the Peripheral … Read more
Hello everyone, I am Goat.I2C signals are a very common type of signal. It is a two-wire serial bidirectional bus used to connect microcontrollers and external devices. Because it only requires two pins (CLK and DATA), the hardware implementation is simple and highly scalable, making it widely used for communication between multiple integrated circuits ICs … Read more
The camera is so small, yet the data is so abundant, it must be using the MIPI interface. In the previous article, we learned about VGA timing, and now understanding MIPI is much easier. MIPI is a digital protocol, so the focus is on how the DATA is encapsulated! It can be seen that it … Read more
You must have encountered this situation: you wrote a piece of code but don’t know how fast it runs? Or you optimized for a long time but can’t provide exact data to prove your optimization is effective. Don’t worry, Python has a super handy tool – <span>time.perf_counter()</span>, which can help you measure code execution time … Read more
