ST7529液晶驅動 The ST7529 is a driver & controller LSI for 32 gray scale graphic dot-matrix liquid crystal display systems. It generates 255
Segment and 160 Common driver circuits. This chip is connected directly to a microprocessor, accepts Serial Peripheral
Interface (SPI), 8-bit/16-bit parallel or IIC display data and stores in an on-chip display data RAM. It performs display data
RAM read/write operation with no external operating clock to minimize power consumption. In addition, because it contains
power supply circuits necessary to drive liquid crystal, it is possible to make a display system with the fewest components.
Ideal for large low power (nanoWatt) and connectivity applications that benefit from the availability of four serial ports: double synchronous serial ports (I² C™ and SPI™ ) and double asynchronous (LIN capable) serial ports. Large amounts of RAM memory for buffering and FLASH program memory make it ideal for instrumentation panels, TCP/IP enabled embedded applications as well as metering and industrial control and monitoring applications. While operating up to 40 MHz, it is also backward software and hardware compatible with the PIC18F8720.
Application Note Abstract
This Application Note introduces a complete and detailed PSoC® project. Telephone Call Logger keeps the detailed record of
approximately 945 phone calls (7-digit number is assumed to be one phone call) including date, start time and the duration of
the phone call in the PSoC device. Users can get this detailed report into the PC environment by using free software, which is
included in the project file. When records reach near full capacity of the Flash memory, an LED will turn on to show that it is
necessary to backup the data. Software gets the data from PSoC, organizes it and prepares a printable version. Additionally, it
sends the date and time information to the PSoC. The external parts in this project can be obtained easily in the market.
NAME Control_AT24Cxx
This collection of routines allows an AT89C2051 microcontroller to read
and write the AT24Cxx family of serial CMOS EEPROMS. This version of the
code is compatible only with the AT89C2051 due to the location of the
data buffer and stack in RAM. The code may be modified to work with the
AT89C1051 by relocating or resizing the buffer and stack to fit into the
smaller amount of RAM available in the AT89C1051. Note that the minimum
size of the buffer is determined by the page size of the AT24Cxx.
