Hello @tbillion ,

Thank you for reporting this issue. For what processor are you compiling? What core are you using?
I ask this so I can try to reproduce your issue, in order to fix it.

Are you using the latest version on Github? In september 2022 I made a fix for the missing _BV on Raspberry Pi Pico (RP2040).
Please note that the last release listed under Releases is quite a bit older (October 2021) and doesn't incorporate this fix yet.

I am using the philhower pico core , on ide 1.8.19. your library is important because I have a customer board that uses the 3x8 keypad feature of the chip and your library is the only one I've found that supports this . If I can help anyway further please let me know .

Hi @tbillion, thank you for the further details. For the library to properly compile on the Pi Pico, you should make sure you are using the latest version, to include the fix I made in september. The added definition of _BV is in the TM16xx,h header file,
If I can find some time I'll do another test with my own Pi Pico and publish these latest changes into a new release, to make it easier for people using the Arduino environment.
