are classes for an IR transmitter and receiver for Sony. One timer is used for the 40khz-PWM IR transmission, driving an IR LED. A second timer captures the rise and fall of the IR receiver (e.g. TL1838 or GP1UX311QS). Since two timers are used, the receiver can see what the transmitter sends out if the IR LED is placed in front of the IR receiver. There is a snapshot (irsonypy.png) of logic analyzer as the test program on a pyboard sends Sony POWER command (0xA9A).
See README file for further explanation and references.
