RH-02 & COM

Postby Guest » Thu Oct 09, 2003 1:53 pm

Hi, I need a couple of tips:

I'm able to read the values from the sample Delphi program, but I'm having difficulties with my COM App.

rh02_open_unit returns TRUE, but rh02_get_value returns FALSE

How can I debug the rh02_get_value function?

It is not possible to debug the function get_value, since the .dll is in compiled format.

When you first call the RH-02 you will get false returned for a couple of seconds until the first correct temperature reading is produced.

You could try using get cycle to find out if a new set of readings have been taken.

Try the RH-02 on with Picolog to check that the unit is connecting and giving values in this application.

Best regards,

Hi, Mark


I added a Sleep(500) after opening the RH-02 and now it seems to be working.
