Mouser Electronics now offers a new class of products for intelligent motor control and machine learning applications NXP Semiconductors MCX Microcontrollers April 10, 2024 – Mouser Electronics, the industry’s leading New Product Introduction (NPI) distributor of the broadest selection of sem

1. General framework: realize the communication between MCU and PC.  The PC (USB interface) sends characters, which are converted to RS232 via USB, and then to RS485 via RS232, and then received by the microcontroller (RS485 interface). 2. The program design is as follows: During the step-by-step debugging process, no

1. UART Introduction          UART (Universal Asynchronous Receiver/Transmitter) is a universal asynchronous receiver/transmitter that works at the data link layer. It includes RS-232, RS-422, RS-485 serial communication and infrared (IrDA), etc. As a low-speed communication protocol, UART protocol is widely used in v

1. Description 1. Serial port UART, baud rate: 9600 When connecting a device, generally only GND RX TX is connected, and Vcc is not connected to avoid power supply conflicts with the target device. 1.1 RS485 standard (+2V ~ +6V: 1 / -6V ~ -2V: 0) 1.2 RS232 standard (-15V ~ -3V: 1 / +3V ~ +15V: 0), MAX232 needs

Light-emitting diode ( LED ) technology has been around for about half a century. A light-emitting diode is a semiconductor device that emits light when there is a voltage deviation . Due to its low power and low voltage operation, the technology was quickly adopted for status indication

ON Semiconductor, driving energy-efficient innovation, introduces a new ultra-low power Bluetooth mesh networking solution based on its ultra-low power RSL10 System-in-Package (RSL10 SIP). Using the RSL10 Mesh platform, engineers can easily implement ultra-low power mesh networks using low-power Bluetooth technology a
