Radio frequency infrared conversion (Xiao Ai speaker Play installation version)

Overview

This is a modified version of https://oshwhub.com/wnet/hong-wai-ye-pin-hu-zhuai-mu-kuai, designed for Xiao Ai Play.
The RF receiver module uses the smaller Far-R1L instead of the standard Hummingbird wireless Far-R1. The transmitter module uses the Far-T2L for slightly stronger signal.
Since I only have 433 devices on hand, I only soldered the 433 module; the 315 module was left unused
. I used the program from the referenced link and flashed it, but it doesn't work for some reason. I'm currently investigating the cause.

Problem solved on November 25, 2023: The infrared transmitter's current-limiting resistor R3 was changed to 0 ohms. If you don't have a 0-ohm resistor, just short it.
Also, due to the rcswitch library, many RF remote controls cannot be decoded, such as my Dooya remote. I read this post https://bbs.hassbian.com/thread-14331-1-2.html and understand the reason, but I don't know how to program it. How can I add my own remote control code? I would appreciate any help from experts passing by.

I have been confused for a long time by a two-stage triode amplifier circuit...
This circuit is a multi-channel infrared receiving circuit. The received signal is a pulse with a level of about 4us. Use A0 ~ A3 to select the channel. It seems to be due to the wiring. Some channels

DSP reads data from FPGA through EMIF interface
Does anyone have a program for DSP to read data from FPGA through EMIF interface? The DSP is c6713 model. I don't need to be the same, but something similar will do.
