2017 Hw3181芯片介绍
上海东软载波微电子Sub1G 新品HW3181芯片介绍
基于 HW3181 应用——之通讯处理要点
HW3181 是一款集成了 MCU 和射频收发模块的 SOC 芯片,可以非常方便的实现 SUB-1G 的无线通讯功能。
由于内部集成了 CORTEX M0 内核的 MCU,所以具备了良好的通讯数据处理能力。
在无线通讯应用中,单纯实现通讯功能是非常容易的,但要实现高可靠性的通讯,就需要在控制软件上下一番功夫了。
下面针对常规的无线通讯应用,给出了一些提高通讯可靠性的处理方式,供大家交流讨论。
S2-LP用户手册
<p>STMicroelectronics S2-LP超低功耗、高性能、Sub-1GHz收发器设计用于射频无线应用。 S2-LP在免执照ISM和SRD频段433MHz、868MHz和920MHz下工作。 编程后,该收发器可在430 - 470MHz、860 - 940MHz频段的其他频率下工作。S2-LP支持的不同调制方式包括2(G)FSK、4(G)FSK、OOK和ASK。 信道间隔为12.5/2
