RDA1846的驱动程序和频率设定

关于RDA1846，RDA1846是一种用于V/U段的调频收发机芯片，与AT1846S兼容，可互换使用。支持DTMF和亚音等功能。可用于2米，1.25米或0.7米的业余频段。

The RDA1846 is a highly integrated single-chip

transceiver for Walkie Talkie applications. It totally

realizes the translation from RF carrier to voice in

the RX path and from voice to RF carrier in the TX

path, requiring only one micro controller.
