Re: Has anyone made an RMT IR Receive library for ESP32/arduino?

Hi I am struggling with trying to receive 433 Mhz data myself. My data is not manchester encoded. I am not sure how to use your bitstream lib. I need to detect the start of a transmission. 15.6 MS LOW followed by 2.6 MS HIGH then capture 64 bits. A Logic 0 is 0.88 ms low and 0.44 HIGH and a Logic 1 ...

I have tried every thing I can think of but I cannot seem to read the port quickly enough. I fail to detect the Logic pulses. The transmitter uses a ...
