Thanks Jan, it should be, but for completeness, here it is:
static GOOD_OR_BAD parse_rgbw_string(char *buf, RGBW_CHANNEL *channel) {
if (sscanf(buf, "%hhu,%hhu,%hhu,%hhu,%d", &channel->red,
&channel->green, &channel->blue, &channel->white, &channel->fade_time) != 5)
{
LEVEL_DEBUG("Parsing failed");
return gbBAD;
}
if (channel->fade_time >= (2^24)) {
return gbBAD;
}
return gbGOOD;
}
Note that I don't get the debug message out.
I did notice that this might be the first time that writes are used on a
ft_vascii field, so I may not be following a well-tested path.
