EV1527

Hi, someone has a example for decode 1527 from module 433MHz ?
I need to connect sensors with this protocol to my project.


Thanks in advance

You are going to have to decode pulse widths with probably the CCP.
The protocol uses a pulse with of 1/4 the cycle time as a '0', and 3/4
as a '1'. It starts with a '0'. then 20 bits that give the serial number of
the device, then 4 bits that represent the four possible buttons.
There have been code examples posted for such pulse width
protocols posted here, so with some adjustments to the timings
involved, one of these could be modified to extract the sequence.

Apparently the devices use ASK modulation.
