Hello There,
I've been experimenting with this Arduino library and encountered an issue where it fails to enter configuration mode. The initialization appears successful, but when attempting to switch to configuration mode, it responds as the following:

I have double-checked the wiring, and everything is set up correctly, so this issue does not seem to be hardware-related. Because configuration mode is essential for proper functionality, this problem seems to effectively prevent further use of the library.

Software info:

• 'DigitalIO' dependency manually installed from latest master
• 'PsxNewLib' version: latest master
• Example used: DumpButtonsHwSpi, with the following modifications (none of them seems to be responsible for the issue, as I have tried without them and got the same result)
  • Attention pin changed to GPIO5
  • In the 'setup' function I added the line while(!Serial);
• At one point, I filled the sketch with Serial.printl-s, and found out that the board is not frozen, just refuses to dump even digital button presses

Hardware and wiring info:

• Arduino used: Arduino Nano RP2040 Connect
  • As this is a 3.3V Arduino, I didn't use any level shifters; only the 1K pull-up resistors between power (3.3 V pin) and COPI, CIPO, SCK - as it is required
• Controller: Joy-it SBC-WLGamepad (in the user manual, it was explicitly suggested to use this library, so must be compatible)
• Acknowledge pin: as nor the example sketch and the readme.md stated that it can be used, I didn't use it as well
