|
|
|
12 ::
|

13
|
|
|
14 import scratch
|
|
|
15 s = scratch.Scratch()
|
|
|
16
|
|
|
17 # to make a broadcast to scratch
|
|
|
18 s.broadcast("from python")
|
|
|
19
|
|
|
20 # to receive an update from scratch
|
|
|
21 message = s.receive()
|
|
|
22 # blocks until an update is received
|
|
|
23 # message returned as {'broadcast': [], 'sensor-update': {'scratchvar': '64'}}
|
|
|
24 # or {'broadcast': ['from scratch'], 'sensor-update': {}}
|
|
|
25 # where scratchvar is the name of a variable in scratch
|
|
|
26 # and 'from scratch' is the name of a scratch broadcast
|
|
|
27
|
|
|
28 # send sensor updates to scratch

|
|
|
31 for data['pycounter'] in range(60):
|
|
