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.

单片机开发 FT245U169 FIFO Loopback This program transmits data through the FT245BM FIFO data bus to the MSP430
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).
