| 11 | |
| 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 | |
| 29 data = {} | |
| 30 data['pyvar'] = 123 | |
| 31 for data['pycounter'] in range(60): | |
| 32 s.sensorupdate(data) | |
