Re: Can we have multiple 1-wire devices on single pin?
Fan won't stop in absence of PWM signal. most fans, without PWM signal applied, will default to 30-50% RPM.
Re: Can we have multiple 1-wire devices on single pin?
Yes, so I came to different solution. I also have PWM output pin, which goes into fan PWM in. So I'll hook DS18B20 to it - When I need to use thermometer, I will stop HPWM output on that pin, read...
Re: Can we have multiple 1-wire devices on single pin?
I have an idea, fan tachometer output will be tied to VDD via 4.7k resistor, as DS18B20 should be. Fan outputs pulses not so fast, so what if I attach DS18B20 to same pin as fan tachometer output?...
Re: Can we have multiple 1-wire devices on single pin?
I want to use PIC16F1503 and have to chain thermometers due to pin count. I guess, running above, complex code might not be possible on this wimpy chip?
The task is as follows:
There are 3 fans...
Can we have multiple 1-wire devices on single pin?
Arduino supports that, but I have not found anything about for that in PBP reference manual...
I want to hook up 4 pcs of DS18B20 to single pin. As I have read, each has unique identifier, so it...
