8051模拟I2C，I2C单字节读写和多字节读写

应用背景ADXL345 是AD 公司的一款 3轴、数字输出的加速度传感器。stm32驱动该传感器进行通信和获得数据。关键技术功能简介：主函数不停的查询ADXL345的转换结果，得到x、y和z三个方向的加速度值（读数值），然后将其转换为与自然系坐标的角度，并将结果在LCD模块上显示出来。DS0来指示程序正在运行，通过按下WK_UP按键，可以进行ADXL345的自动校准（DS1用于提示正在校准）。

应用背景The CMX990 provides, on-chip: a flexible, formattable GMSK packet and freeformat modem, a dual synthesiser fed from an external source, IF and RF transceiver stages for both Rx and Tx modes, and auxiliary ADCs and DACs for system control and monitoring.关键技术Operating in the range of 400MHz to 1GHz at data rates of 4 to 16 kbps. This single-chip, half-duplex device requires a minimum of external components, keeping end-product board size, power consumption and cost to an absolute minimum. The versatile GMSK modem is configured for either packet and freeformat data operation via an efficient task-oriented Rx and Tx format and command structure combined with data scrambling, interleaving and FEC and CRC capabilities. Rx data acquisition, extraction and tracking functions use Rx data-quality feedback to support varying signal environments. IF and RF functions in the Tx path handle all the signal processing requi
