Um, it was giving exactly *two* OWFS specific calls, which are pretty
understandable. What's the problem?

If you'd show me the log, I could tell you why.

If you don't like python and have problems setting up you C compiling
environment, why don't use one of the numerous *other* language
bindings? Ow the owshell tools?

Kind regards

Please understand this very simple test program first:

=== Makefile 

.PHONY: all clean
CFLAGS=-I /opt/owfs/include/
LDFLAGS=-L /opt/owfs/lib64/ -lowcapi

all: owcapitest

clean:
-rm *.o owcapitest

owcapitest: owcapitest.o
$(CC) $(LDFLAGS) -o $@ $^

=== owcapitest.c 

#include 
#include 
#include 

int main(int argc, char* argv[]) {
size_t   rs;
char*buf;
ssize_t  rss;

if ((rss = OW_init("-s localhost:4304")) < 0) {
perror("OW_init failed");
exit(EXIT_FAILURE);
}

if ((rs = OW_get("/uncached/10.AE9C54020800/temperature", , )) < 
0) {
perror("OW_get failed");
exit(EXIT_FAILURE);
}

printf("%s\n",buf);
}
=


Kind regards

2017-01-13 Thread bdrmachine 
 Wouldsomeone Please help me with the input string needed forthe owcapiexample 
program. I am trying to read my 18b20 sensors that areattached to my Raspberry 
Pi 3 using the I2C interface. I can readthem with my browser @ 
“localhost:2121”. The problem is I cannot get the example code that was loaded 
at(/usr/share/doc/libowfs-dev/examples/owcapi/C) to work. I need helpfiguring

https://sourceforge.net/projects/owfs/ is the official repository I
think. Does not owserver already handle the DS2450?

Dear Colin,

how can I get the source code of the version, described in the message, 
because I need to modify the code, to see what happen on the 1-wire bus.
Because I am working on a 1-wire Slave AVR based for a DS2450.

Best regards
R.
