Teensy 4.1 Compilation error: 'SdFatSdioEX' does not name a type

[Francesco-75]

Teensy 3.6 is basically out of stock. Would be nice if you can port the project to be used with Teensy 4.1 (SmartMatrix lib already support it nowadays). i have tried to do that but unfortunately seems actually something going wrong with the SdFat lib (using the beta one that has the teensy 4.1 support):

you always have:
Compilation error: 'SdFatSdioEX' does not name a type

Naturally i have changed these lines on the source accordling to the new SmartMatrix lib:
#include <MatrixHardware_Teensy4_ShieldV5.h>
#include <SmartMatrix.h>

Any help will be appreciated

"Sorry, I'm late to the party. I found this repository and wanted to try it, but the Teensy 3.6 is not available anymore. So I ported the code to the Teensy 4.1 with a V5 shield. It took me a couple of days and a headache, but here is the result: https://github.com/heidepiek/Teensy2DMD-T4.1-Edition. Hope it helps others who want to use the newer hardware!

I have also done a port for the new Teensy: https://github.com/Francesco-75/teensy4toDMD

I will try yours now! I've been trying to alter the code for a couple of days as well, and yesterday I finally succeeded. Then I found your repository, but I hadn't tried it yet. When I saw your Issue about the errors, I thought your code wasn't fully functional yet. Sorry! :-( My version has the ZMODEM and SdFat fixes working if you want to compare.

[Francesco-75]

Awesome, my code has not yet the zmodem protocol fully functional so i'm rrally happy you have it ported succesfully. Can't wait to test it! Thanks for sharing.

That’s great to hear, Francesco! I’m glad I could help out. I spent quite some time wrestling with the SdFat libraries and the ZMODEM timing on the Teensy 4.1, so I’m happy to save you the trouble.

Feel free to test it out and let me know if it works for you. If you want to integrate parts of my code into your project, go ahead! That’s what the community is for. Enjoy the RetroPie boot screen too—it's a nice little extra I added.

For those interested in a working version for the Teensy 4.1 and SmartLED Shield V5, I've created a port that also includes a Real-Time Clock (RTC) and EEPROM memory settings.
