<callback>...</callback> 关键字,调用C++的成员函数,修改成员变量的值。如本程序中xml中的语句: <callback>set_angle_offset($angle)</callback> 对应C++中函数如下: 1 void set_angle_offset(double angle) 2 { 3 d_offset_angle = angle; 4 } 1. 2. 3. 4. 除此之外,还要注意参数类型匹配。WX...
首先,要在模块对应的xml文件中,在<make>块的下面,加入<callback>模块。(如果写在<make>上面,编译流图里就没这个模块,所以要注意一下顺序) 之后,在对应模块中要写这个两个回调函数,这两个回调函数有俩个参数(对于python模块),第一个是self,第二个是变量。 这样就完成了模块对动态参数的支持。对于C语言模块,...

安装成功之后，GRC界面可以运行，但是uhd_fft.py亲测不可用，报错如下：AttributeError: 'gr_hier_block2_sptr' object has no attribute 'set_callback'当时在这个地方纠结了很久，用apt和packages都尝试过，均不行，也许是哪设置有问题，不知道该如何调试。最后尝试了用脚本安装，此方法简单可行，并且...
