Hi, I recently made a scrolling text using wemos nodemcu v1 and transmit characters to it via WIFI server. I want to interface a SD card with it so that whenever there's no new message coming in from the web server, it will automatically read the text content of the sd card then dump it on the display. The problem is, those HSPI pins was used by the matrix. Is there a possibility of using the SDIO pins for the card, and do u have any tutorials about that SDIO pins? Thank you in advance.
The same idea should work just fine on the ESP32, the pins will probably be different, though. Let me find some time to slap together some code for you and i'll come back and reply with a link!
