You may also look thread http://www.cocoontech.com/forums/index.php?showtopic=11392 , I recreate Java library which look little better if you use more devices :huh: and couplers. Regards, Dubravko

Hi Dan, I suggest that you open new thread with list of feature You like to have, it will be easy to continue discussion :P ... PIC or AVR will be fine, I also searching for some good software and implemetation, I found some library for microBasic and 1-wire. Dubravko

Hi, Please provide picture of your board, that may help, also I found that is very easy to solder solar sensor on wrong direction, check if picture of solar module on http://www.hobby-boards.com/catalog/popup_image.php?pID=57 show same direction as your solar sensor. Regards, Dubravko

You can , but from AD converter part it is only 0-0.25V (register change highest bit if you change polarity on connectors ). Indirectly that mean AD converter dosnt measure voltage difference of 0.5V (that have impact of measuring precision and reading value) . Regards, Dubravko

Hi Dan, according my knowledge that is possible, but that doesnt extend measuring range 0 - 0.25 V , only what is change is highest bit in Vsens register. Dubravko

Hi, You may use few Java program/examples if you like . DUbravko

Ele34, please read http://datasheets.maxim-ic.com/en/ds/DS2438.pdf document. If you dont understand what is written in it you have two option or believe what other people tell you, or learn how understand what is written in it. On this way, you continuously ignore technical documentation, and...

Yes I am strange person, ask every one who know me :o ... If is up to you or me I wouldnt care about fact we written here, but I reed a lot of wrong information on this forum, because people dont read technical documentation or dont understand how system is working... finally we talk about...

Sorry but I must replay to your post , because you read commercial material instead of technical documentation which is provided on follow URL: http://datasheets.maxim-ic.com/en/ds/DS2438.pdf You are not able to read current directly from DS 2438 chip (no memory register for that) , especial...

Just look schematic for dual counter and You will know what to do :blink: And then check if I am correct ... :D ... You need to connect counter port and +5V , and dont connect +5V connector to other part of network or you will drain a battery. Dubravko

Are you read DS2438 documentation ? And very precise that voltage may be from -0.25V till +0.25V. Chip doesnt measure any current at all. But software may return you current if you provide measuring resistor value. Finally I double check HB schematic, and doesnt see any similarity in that two...

I have Davis raingauge and that device work very god with HB dual counter board, for other device, I may only said it is possible , but you will need some more hardware work done before connect to 1-wire chip (try with some AD converter like DS2438) Dubravko

Very simply, float energy = (float) (Vsens/meResistor*1730463); Energy is in W/m2 meResistor is 390 With second post you make some confusion, because HB solar part doesnt work on that way. Dubravko

Hi, every reading have are good enough if you know what are you reading ... make any sense to you ? :) ... To be clear what are you doing , need also knowledge how system work, what you expect to be happened, and what are working parameter. I didnt produce this solar panel reading sensor...

After few days of researching (mostly because of non consisting information and documentation) i finish few new classes. All of thous are prepare to help working with DS2423 chip (reading counter, reading and writing memory (4kb), and some memory function). Newly add class will not solve any...
