Sdi-12 on mbed

Hi everyone, Is there an sdi-12 library written for mbed? I have a sensor that uses sdi-12 protocol and i want to interface it with an mbed board. I tried searching the web but i cant find the answer. Please help.

Thanks.

Hello,

I had same problem couple of weeks ago. My sensor was Decagon GS-3... Both using SDI-12 and DDI(one wire, only sends)

This sensor is working when a voltage applied from its power cable from one of GPIO pins of mbed f401.. After that excitation it immediatly returns its read values via its Tx line... And i attached that tx line to Rx pin of F401... and kept it in a string with Rx interrupt routine...

I suggest you the check your sensor, if this method is usable or not...

Regards

hi thanks for your response. actually what i want is the actual SDI-12 protocol so that i can use the default sdi commands for the configuration of the sensor. thanks
