I needed to know how to obtain the rtc values from the PK2200 BIOS so I
asked the Rabbit support I was given an answer which did'nt worked and
also asked to look at the sample program named RTCTEST.C the file was
not in the sample library and some of the topics regarding RTC is not
found in the PK2200 manual even though the Index says it is in some of
the pages. Does PK2200 really have such a function or am I just
searching for something that was no longer implemented on a PK2200.

I just took a look at one of our old PK2200 projects and we just used
tm_rd to read the time. At one stage ZWorld changed from using Toshiba
RTC chips to using Epson which resulted in library changes. This should
all be in the latest version of 5 (5.26) but if you're using an older
version you may need to port the library back to it.

Were using Dynamic C v6.x our device is a z180 PK2200.
what libraries should I use, I already received an from rabbit about
RTC and a sample RTC program but it didnt work it still displayed an
8 on every variable I tried to use from the struct tm variable. or
atleast everytime i read from the clock "tm_rd(&variable);" all the
variables in tm will chang into 8. did my clock fail or is my methods
obsolete?

Here's an email I'm gonna send them now! If any of you can spare some
advice regarding the problem I'd appreciate it.

The idea of obtaining the RTC value from the PK seemed so simple I
can't understand why I'm it's not working even their sample is not
working well, I plan to request another PK to use but it's unlikely
that I'll get a different result because I already got
another "8:8:8" on the first time i tried using another PK?

I tried the sample but to it was not able to display anything only a

My device is a PK2200 with a number on the right side of the

Sorry I can't help you with DC6 as I've never used it.

Just a tip with getting support. Keep the example as simple as possible
e.g. just hardcode some values into a tm struct, use tm_wr, then read
back the results with tm_rd.

Nathan

thanks for the advice although were going to change the approach in
getting the time values. We opted to use a variable for seconds and
then increment it per second rather than rely on tm_wr and tm_rd
although, 'how to use tm_rd and tm_wr' may be a question that will
keep me up at night. It really seemed simple I'm still not sure if the
problem was in the programming or in the hardware of the PK.
