USB to RS232 Adapter with FT232 - We employ two UART boards in the
course, one which can be connected to the serial connector of the PC
(UART-RS232), and a second that can be connected to a USB port (UART-USB).
The former is used in the lab and is part of the standard take-home
equipment. The latter is part of the (limited!) number of take-home targets
for students who are working on a Laptop without serial connector. In both
cases, communication is done with the UART module of the microcontroller

USB to RS232 Converter - Why build my own USB to RS232 converter
when there are adapters already available from many suppler? The Answer is
simple: Neither the strand "USB to RS232 converter" actually worked
*properly* with all the devices I tried. But, They did not seem to support
ALL the RS232 lines. The USB to RS232 converter using the FT8U232AM and a
Maxim-IC MAX235

USB to RS232 Dongle - With serial and parallel ports being phased out on new
computers, hardware designers and hobbyists have no choice but to convert the USB port
back to RS232 serial. FTDI have a very nice chip that does just that, the FT232AM.
This chip converts USB to a standard high-speed serial port. The bonus with FTDI is
the drivers are already written for you. All you have to do is design the hardware and
download the serial USB drivers from FTDI's web site.

USB to Serial Adapter RS-232 - USB to Serial Adapter RS-232 Serial Port to
USB The USB to Serial adapter (converter) lets you use a serial PDA, GPS, cell, etc.
with a standard USB port. This adapter is the easiest way to add a serial port
to your computer. Many PDAs, digital cameras, GPS units, barcode scanners, and other
equipment require a serial connection, and many newer computers don't have serial
ports.

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: 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-bandwidth
characteristics.... [Design Feature 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 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.

change is the replacement of the analog sensors with a Sensirion SHT11 digital
temperature and humidity sensor
