Thereís no known clock reference being fed into it.
It can currently be any of three clocks so itís unknown.
The picís clock is set to HS, and is clocked by one of the three signals connected.
It's easy, when PIC have internal osc...
You can use same method to calibrate internal OSC, when OSCCAL value is erased.
Just feed in known clock reference and adjust internal clock Until you get...
If it is figured out I want it outed, and if not Iíll take it to the world of YouTube :D but will then give it up ;)
So where's the LIKE button?
This is the hardware....
A hardware selectable logic buffered clock, or you can turn them all off and the pic won’t run at all.
Hi Guys :)
Do you think it's possible for a program running on pic 16F628A with no additional hardware,
connected only to:
1) a power supply
2) a single wire clock signal to pin 16 CLKIN
before you go too far down this track you might like to research some other devices or at least have a way to calibrate these things. I now have three sensors in the same room 2x dht22, 1...
with a little bit more code now it can do dht11 and dht22 sensors just by setting a var sens_type to 11 or 22
