USB to Serial Interface - USB to serial interface is based on the powerful FT232 chip from FTDI. It enables very easy
connection of the user's application to the PC via the USB port, without necessity of any deep knowledge about
the complicated USB problems. FT232 chip is capable to transfer data at speeds up to 1M Baud in RS232 mode and up
to 3M Baud in the RS485 mode. Schematic contains the on-board serial EEPROM (93LC46) for storing the ID data (VID,
PID, serial number and description strings). . . .
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. . .

USB: a Neat Package with a FeW Loose Ends - 10/24/96 EDN Design FeatureThe 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-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 LCDCThe 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
LM3622 Li-Ion
Battery Charger Controller. . . .

XSPIII Cable Interface - that configures the CPLD so it emulates a Xilinx Parallel Cable III interface. This allows
you to use the WebPACK programming tools through the simple XESS downloading cable. . . . [Application Note by

XY Keypad uses
µC's Serial Port - 10/10/96 EDN Design Idea Interfacing
an X-Y keypad to a microcontroller usually uses a parallel port of 8 bits or more. But with the circuit shown in
Figure 1, a more efficient interface using a microcontroller's serial port reduces the number of connect. . .
