I'm playing with ESP12F module and I wanted to read IR codes from my remote. I looked at documentation, and it
appears that your input pins have possibility to be connected to internal sigma-delta module, but I never saw actual code
that could read or filter IR codes using this method. Is there a way you could share some info about the internal implementation
of your sigma-delta circuitry and associated C code that allows user to read IR codes (using interrupt handler ?).
In a few forums ( http://internetofhomethings.com/homethings/?p=899 ) I saw that there is a schematic of IR diode being
connected to 4.7K pull-up resistor to pin GPIO13, which suggests that this simplified schematic depends on some analog
part that I didn't find in any hardware sheet. Your "Technical Reference 1.1 PDF" just shortly mentioned GPIO5 port for "IR Rx".
Others are using IR module with well defined binary output, but since I'll be using IR diode, I'm more interested in the
simplified schema (if this is even possible).
Thanks for any help.
Best regards, Bosko
