I need to connect esp32 and USB_Host_Shield now, but I can't connect, can I know why?
I'm using ESP32S and I'm using something called USB_Host_Shield.
The library is using USB_Host_Shield_2.0.
Circuits At Home 2011
USB Host Shield Quality Control Routine
Reading REVISION register... Die revision invalid. Value returned: 00
Unrecoverable error - test halted!!
0x55 pattern is transmitted via SPI
Press RESET to restart test
I think ESP32 is all added to the library, but I don't know why not.
If you look at the writing, Shield needs to revise something. What should I do?
Is it possible that it won't connect?
No, it's a problem that can't be connected to shield and ESP32. I think it's an ISP communication problem. I looked up the link and ran it because it's a test program, and the bottom is the result.
