Hi folks,
I'm trying to get a new driver working, and I can't seem to get my write
functions called.
Here's the pertinent bits (from ow_iergbw.c):
READ_FUNCTION(FS_r_get_channel_0);
WRITE_FUNCTION(FS_w_set_channel_0);
static struct filetype IERGBW[] = {
F_STANDARD,
{"all_off", PROPERTY_LENGTH_YESNO, NON_AGGREGATE, ft_yesno,
fc_static, NO_READ_FUNCTION, FS_w_all_off, VISIBLE, NO_FILETYPE_DATA, },
{"channels", PROPERTY_LENGTH_INTEGER, NON_AGGREGATE, ft_unsigned,
fc_static, FS_r_count_channels, NO_WRITE_FUNCTION, VISIBLE,
NO_FILETYPE_DATA, },
{"channel0", 3+1+3+1+3+1+3+1+8+1 /* "r,g,b,w,time" */,
NON_AGGREGATE, ft_vascii, fc_volatile, FS_r_get_channel_0,
FS_w_set_channel_0, VISIBLE, NO_FILETYPE_DATA, },
};
static ZERO_OR_ERROR FS_w_set_channel(BYTE channel, struct one_wire_query
*owq)
{
RGBW_CHANNEL channelData;
channelData.channel = channel;
LEVEL_DEBUG("Channel=%d string='%s'", channel, OWQ_buffer(owq));
RETURN_ERROR_IF_BAD(parse_rgbw_string(OWQ_buffer(owq),
));
RETURN_ERROR_IF_BAD(OW_w_set_channel(, (PN(owq;
return 0;
}
static ZERO_OR_ERROR FS_w_set_channel_0(struct one_wire_query *owq)
{
LEVEL_DEBUG("here");
return FS_w_set_channel(0, owq);
}
And here is the debug output:
Successful read:
