Request for SDIO Support in Adafruit_Sdfat Library for SAMD51

[akarimiz1]

Dear Adafruit Support Team,

We are writing to formally request the addition of SDIO support to the Adafruit_SDFAT library for the SAMD51 microcontroller.

The current implementation of the library relies on the SPI interface, which while functional, is limited in data transfer speeds compared to the SDIO interface. With the increasing volume of data being processed in modern applications, the ability to leverage the higher speeds offered by SDIO is becoming increasingly critical. The SAMD51 microcontroller is capable of supporting SDIO, making it an ideal platform for high-speed data transfer applications.

While we understand that SDIO support is available in CircuitPython, many of our projects are developed in C (Arduino) for performance and control reasons. Having to migrate entire projects to CircuitPython solely for SDIO access is time-consuming and inefficient. We believe that adding SDIO support to the Adafruit_SDFAT library with a simple mode change option in the C code would be a significant benefit to the developer community.

We believe that integrating SDIO support into the Adafruit_SDFAT library would greatly enhance its utility and expand its applicability to a wider range of projects. We look forward to your positive response to this request.

Thank you for your time and consideration.

Sincerely,
Ahmad Karimi
