I think having the work fn return "-1" will cause the flowgraph to exit, so you could potentially have a "self.count = 1" in __init__ and then when you've output >= self.count,
have work return -1

I wrote a simple source block that reads a string (as a parameter) and outputs the corresponding array of bytes.class myblock(gr.sync_block): def __init__(self, helloMsg): gr.sync_block.__init__(self, name="myblock", in_sig=None, out_sig=[numpy.byte]) self.helloMsg = helloMsg def work(self, input_items, output_items): out = output_items[0] test = array.array('B',self.helloMsg) for j in range(len(test)): out[j] = test[j] return len(output_items[0][:len(test)]) |
