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

此源码能驱动型号为8989的液晶屏幕，能够与stm32兼容， 在工业控制现场，经常需要将检测仪器在现场检测到的信号传输到集散控制系统来统一管理和控制。但是，此传输距离往往是远距离传输，如果使用电压信号来传输的话，由于传输的导线都是有阻值的，所以势必会造成电压信号的衰减，在此过程中还会受到噪声干扰，从而导致集散控制系统接收到的信号不稳定。为了解决上述问题，这里改为4~20mA模拟电流信号，原因是采用电流信号不容易受到干扰，在传输过程中电流信号不会衰减。
