Temporary, one could add ignore the format-truncation error from GCC:

snprintf(buffer, sizeof(buffer), "%s", chip);

into

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wformat-truncation"
    snprintf(buffer, sizeof(buffer), "%s", chip);
#pragma GCC diagnostic pop

In main.cpp:covertChipType(...)

Looks like this might be an actual fix:

#70

Hi,
as buffer is 5 characters you can just change the line 1493 to:
snprintf(buffer, sizeof(buffer), ".4%s", chip);
(according to https://cplusplus.com/reference/cstdio/printf/)
