Description: This program demonstrates a half-duplex 9600-baud UART using
// Timer_A3 using no XTAL and an external resistor for DCO ROSC. DCO used for
// TACLK UART baud generation. The program will wait in LPM4, echoing back
// a received character using 8N1 protocol. On valid RX character, the
// character is echoed back.
// Using a 100k resistor on ROSC, with default DCO setting, set DCOCLK ~ 2MHz.
// ACLK = n/a, MCLK = SMCLK ~2MHz DCOCLK

MSP-FET430P140 Demo - USART0, SPI Interface to HC165/164 Shift Registers
Description: Demonstrate USART0 in two-way SPI mode. Data are read from
an HC165, and same data written back to the HC164.
ACLK = n/a MCLK = SMCLK = default DCO = UCLK0 = DCO/2
* USART0 control bits are in different SFR s from other MSP430 s *
FT245U169 FIFO Loopback
This program transmits data through the FT245BM FIFO data bus to the MSP430F169 on Port 4.
The data is decremented and sent back out of Port 4 to to FIFO on the FT245BM.
Use Hyperterminalto send and receive data.
FIFO control lines are on Port2 (P2.0-P2.3).
xl2tpd is an implementation of the Layer 2 Tunnelling Protocol (RFC 2661).
L2TP allows you to tunnel PPP over UDP. Some ISPs use L2TP to tunnel user
sessions from dial-in servers (modem banks, ADSL DSLAMs) to back-end PPP
servers. Another important application is Virtual Private Networks where
the IPsec protocol is used to secure the L2TP connection (L2TP/IPsec,
RFC 3193). The L2TP/IPsec protocol is mainly used by Windows and
Mac OS X clients. On Linux, xl2tpd can be used in combination with IPsec
implementations such as Openswan.
ADM6993F/FXFiber to Fast Ethernet Converter (TS1000 CPE Complied)
The ADM6993F/FX is a single chip integrating two 10/100 Mbps MDIX TX/FX transceivers, a three-port 10/100M Ethernet L2 switch controller, and one OAM engine to meet demanding applications, including Fiber-to-Ethernet media converters, especially the fiber to the home (FTTH) media converters. The ADM6993F/FX feature set includes link pass through (LPT), TS1000 OAM frame receiving/processing/transmitting, programmable link status LED display, various loop-back modes, and one configurable MII ports for snooping/inserting OAM frame from/to 100Fx. The ADM6993FX is the environmentally friendly “green” package version.
an approach for capturing similarity between words that was concerned with the syntactic similarity of two strings. Today we are back to discuss another approach that is more concerned with the meaning of words. Semantic similarity is a confidence score that reflects the semantic relation between the meanings of two sentences. It is difficult to gain a high accuracy score because the exact semantic meanings are completely understood only in a particular context.
In the previous article, we presented an approach for capturing similarity between words that was concerned with the syntactic similarity of two strings.
