This program prints the C8051F124 die temperature out the hardware UART at 115200bps. This example uses the internal 24.5MHz oscillator multiplied by 2 using the On-Chip PLL (SYSCLK = 49MHz).
This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, controlling On-Chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.
This program demonstrates operation of ADC0 in polled mode. The ADC0 is
// configured to use writes to AD0BUSY as its start of conversion source and
// to measure the output of the On-Chip temperature sensor. The temperature
// sensor output is converted to degrees Celsius and is transmitted out UART0

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.

ST7787 芯片的SPEC，比亞迪2.4inchLCM的SPEC。The ST7787 is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 720 source line and
320 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial
Peripheral Interface (SPI), 8-bits/9-bits/16-bits/18-bits parallel interface. Display data can be stored in the On-Chip display
data RAM of 240x320x18 bits. It can perform display data RAM read/write operation with no external operation clock to
minimize power consumption. In addition, because of the integrated power supply circuits necessary to drive liquid crystal,
it is possible to make a display system with the fewest components.
