CRC16.h or crc16.h?

[Paul-Reed]

Hi Rob. I'm re-using an Arduino IDE sketch that I last successfully used probably 7 years ago, and it's now no longer compiling. I'm getting the error Compilation error: util/crc16.h: No such file or directory I've searched, found & added your library, but your library is spelled in capitol letters CRC16.h, whereas in my sketch it's crc16.h and of course therefore does not resolve things.

Has something changed in it's naming protocol, or may I have possibly used a different library. Any help or guidance would be appreciated.

Hi Paul, my library did not change (there is a big change underway bit that should be no problem).

I expect the util/crc16.h is from another library, and maybe even it is a specific crc16 (in terms of parameters)

It might be part of

• https://www.nongnu.org/avr-libc/user-manual/
• https://www.nongnu.org/avr-libc/user-manual/crc16_8h_source.html as it uses the util/crc16 path

Have you upgraded the IDE to the latest version - I'm using 1.8.19

Yes, it's a fresh install - v2.1.0 I've tried your link, which also results in errors, but thanks for the suggestion.
