Starting from the BLE background and market analysis, we will introduce the ON Semiconductor BLE family and focus on analyzing the new functions of ON Semiconductor's latest BLE5.2 Bluetooth chip RSL15, such as CryptoCell-312 and TrustZone security support, Angle of Arrival (AoA) and Angle of Departure (AoD) positioning support and Smart Sense ultra-low power mode.
The LMS ( least mean square ) algorithm has been widely used in the fields of adaptive filters, adaptive antenna arrays, etc. due to its fast convergence speed and simple algorithm implementation. In
The question is this: I just checked the information. I found that I need to add a pull-up resistor to the microcontroller pin. Connect to the base of the transistor, and then control the relay. But s
The serial port sends data one bit at a time and receives data one bit at a time. Excluding the start bit and the stop bit, there are only 8 bits of data left. When 8 bits of data are received, an int
