DataDraw is an ultra-fast persistent database for high performance programs written in C. It s so fast that
many programs keep all their data in a DataDraw database, even whi le being manipulated in inner loop s
of compute intensive appl ications.
// This program measures the voltage on an external ADC input and prints the
// result to a terminal window via the UART.
//
// The system is clocked using the internal 24.5MHz oscillator.
// Results are printed to the UART from a loop with the rate set by a delay
// based on Timer 2. This loop periodically reads the ADC value from a global
// variable, Result.

HISTORY:
Mar.25.2002:purnnamu: S3C2400X profile.c is ported for S3C2410X.
Mar.27.2002:purnnamu: DMA is enabled.
Apr.01.2002:purnnamu: isDownloadReady flag is added.
Apr.10.2002:purnnamu: - Selecting menu is available in the waiting loop.
So, isDownloadReady flag gets not needed
- UART ch.1 can be selected for the console.
Aug.20.2002:purnnamu: revision number change 0.2 -> R1.1
Sep.03.2002:purnnamu: To remove the power noise in the USB signal, the unused CLKOUT0,1 is disabled.
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).
