Circuit playground firmware

In the folder ./playground_firmware are two scripts:

• decode.py

• transmitter_routine.py

just rename the one you want to load as code.py and copy it in the circuit playground, the routine will start automatically. For details refer to the official help page . The library adafruit_irremote.py is required. A copy is available in the playground_firmware/lib directory.

decode.py

This script is used to decode the signals from the remote. An example of the output printed when pressing a button on the original remote is:

Received:  [3998, 493, 1515, 507, 490, 502, 496, 497, 491, 501, 498, 505, 493, 500, 498, 495, 493, 501, 1488, 533, 1514, 499, 1508, 512, 1516, 495, 1512, 511, 1518]
Decoded: 0x 0x203f
Decoded: b 10000000111111

transmitter_routine.py

This script convert the received bits over serial link into pulses for the IR transmitter. The red led of the express playground blinks when transmitting.
