关于CC1101遥控距离程序调试问题附单片机程序

ID:421668 · 发表于 2022-3-23 09:17

如题，我用了两个CC1101模块做收发遥控，然后发射功率我设置到了最大，可是空旷距离很不理想。我看手册上说怎么也得200米，可是我的只有二三十米的样子，论坛的友友们，帮忙指点一下我的程序看看是不是哪里还是设置的不对啊。CC1101我买的现成模块，硬件电路应该没有问题。我也怀疑问题出在我的程序里面。
单片机程序如下：

你应该把手册也发上来，你这样还得让人自己下载浪费时间啊。

ID:584814 · 发表于 2022-3-23 12:00

接发不正常，多是软件问题；
接发功率不够，多是硬件问题。

ID:45879 · 发表于 2022-3-23 14:42

C1101模块卖家应该有调试好的程序，试试他的程序；
要是测距离，程序把功率开到最大，做个一直发的主机，从机一直接收，收到对应的数据后灯闪烁。（发送的数据包不要太大）
你天线如何处理的？上个图

用了他们给的程序测试了也是距离不够。我也怀疑过是不是电线设置不对。我的电线就是买的模块带的弹簧电线。
