USB/TTL Serial Cable: Extension & Supplement -  Two years ago, I presented here the USB/TTL serial conversion cables from FTDI — wonderful communication and debugging tools. The increasingly frequent use of ARM. must register on this site. . .  [Published in Elecktor July/Aug, 2010]

USB: a Neat Package with a FeW Loose Ends -  10/24/96 EDN Design Feature  The USB for PCs can automatically configure and power peripherals. But, as I learned in this hands-on project, early USB adopters may face a substantial system-level design effort. They also need to carefully examine USB data-. . .  [by Richard A Quinnell, Technical EDFtor]

USB-AVR 323 Board -  schematic for an ATMega323 boards The main interface to this board is USB via the FTDI USB-Serial converter chip. . . 

USB-Based Thermocouple Temperature Measurement System Using ARM7  -  In the source code, an ADC sampling rate of 4 Hz is chosen. When the ADC input PGA is configured for a gain of 32, the noise free code resolution of the ADuC7060/ADuC7061 is greater than 18 bits. , Circuit Function and Benefits, The following features of the ADuC7060/ADuC7061 are used in this application:, Primary 24-bit Σ-Δ ADC with programmable gain Amplifier (PGA): The PGA is set for a gain of 32 in the software for this application. ARM7TDMI® core: The powerful 16-/32-bit ARM7 core with integrated 32 kB flash and SRAM memory runs the user code that configures and controls the ADC, processes the ADC conversions from the RTD, and controls the communications over the UART/USB interface. . .  [Analog Devices-Circuits from the Lab]

USB-LCD with PIC MicroController & FT232 -  USB LCD/VFD Controller is a HD44870 based LCD/VFD controller via USB interface. The control command is compatible with Matrix-Orbital's LCD module. So, you can use any MO friendly software to control this baby. Such as LCDC.  The firmware are based on David Potter's Serial LCD/VFD Display, but I almost rewrite the entire code. . . . 

USB-PC 8-CH Power Switch -  Powerswitch provides 8 bits of parallel output intended to switch e. g. the power supply to electronic devices. The Powerswitch firmware is accompanied by a command line tool for Unix to control the device. (The command line tool can also be compiled on Windows using minGW and libusb-win32. ). . . . 

USB-Powered Lithium-Ion Battery Charger -  With a maximum power rating 5. 25V/500 mA, the USB power bus is a great source for charging a single-cell Lithium-Ion battery. The circuit in Figure 1 shows how to build a USB-powered single-cell Li-Ion battery charger using National Semiconductor s LM3622 Li-Ion Battery Charger Controller. . . . 

USB-Powered PC Lamp -  This white LED lamp lets you use your PC or laptop at night without disturbing others’ sleep. It produces a soft white light just enough to see the keyboard in darkness as well as when the ambient light is poor during daytime. . . .  [© EFY Enterprises Pvt. Ltd. All rights reserved]
