Gentlemen,
long time no see
Tom, I knew this driver was in good hands with you. I’m truly impressed.
I implemented DEL’s C3/C4 and refined the design, see next post.
Have them in my hands already, looking very good, just no time for building…
Lexel, the temperature sensor is a direct implementation from RMM’s v2. I never used it myself, just kept it in the design. As far as I understand the sensor itself has 3 pins: T+ and T- are its power supply (hence T+ to the output of the LDO) and Tin is the sensed value. Tin is fed into the Attiny Pin3 through a 2-resistor voltage divider (Rt1/Rt2) to get the voltage down to a level the Attiny can evaluate (probably below 1.1V as for the LVP input at Pin7).
But now let me introduce you to v5.
I heard Photobucket is not the same anymore… Interestingly all my pics still show. I keep my fingers crossed, but I need to get a different hoster.
