Desktop charging station

Overview

Having learned about JLCPCB hardware for so long, I'm finally contributing to JLCPCB's hardware community!
The input PD fast charging uses a 224kbps input as a decoy. The other two ports utilize a discarded computer charger, so they use the most common Lenovo square port and DC 2.5, meaning only one input port can be used at a time.
Fast charging output:
Supports PD 2.0/3.0 and PPS
, supports Quick Charge 3.0+/3.0/2.0 protocols - supports Xiaomi Charge Turbo 27W protocol, Huawei FCP/SCP/HVSCP protocols, Samsung AFC protocol, USB BC1.2 DCP, and Apple 2.4A charging specification
to adjust the maximum output current to 3A.
Each output port uses an INA226 to detect charging information.
The touchscreen is driven by an STM32 microcontroller and LVGL library.
Reserved: One PWM port, one ADC detection port, and one 7-pin 2.54 port for connecting to a DWIN serial touchscreen.
Reserved: One 4-pin 2.54J interface for 3.3V and 5V power output.
Reserved: One 4-pin 2.54 interface for microcontroller downloading and debugging.
A simple usage video is attached.

What is the reliability of dual-tone multi-frequency data transmission on the public telephone network?
There is a project that requires using DTMF to transmit a long string of characters on a public telephone network. I would like to ask if anyone who has done DTMF transmission can tell me what the tra
