| | DS1820 sensors?
|
|
Has anyone been able to interface the DS1820 temp sensor (or any other 1-wire device) to the handyboard/miniboard/whatever? I'm working on a project where it'd be nice if I could figure out how to interface to these devices. (27 years ago, 27-Apr-97, to lugnet.robotics.handyboard)

(...) The way it really works is that if the analog value is 255 then it returns 0 other wise it returns 1. So you can modify the lib_hb.c file and change the constant, or use the analog() call on the pin. --Chuck (27 years ago, 26-Apr-97, to lugnet.robotics.handyboard)

| | Using analog ports as digital
|
|
The HB manual says that if you us the digital command on an analog port, the result is true if analog measurement is <127, and false for analog>127. I tried this and it does not seem to work that way. I get true for 0<analog<255, basically (...) (27 years ago, 26-Apr-97, to lugnet.robotics.handyboard)
