Fix a linux segfault I was getting

hippyau commented 3 years ago

Ah, yeah that didn't go to plan...

I just added...

if (!Display::Get()) return 0; to... 

uint16_t json_get_display(char *pOutBuffer, const uint16_t nOutBufferSize) {
    if (!Display::Get()) return 0;
    const bool isOn = !(Display::Get()->isSleep());
    const uint16_t nLength = static_cast<uint16_t>(snprintf(pOutBuffer, nOutBufferSize, "{\"display\":%s}", isOn ? "true" : "false"));
    return nLength;
}
