Hi, may i ask you something?
How can you generate a 3 states ( +Vo, gnd -V) signal (kinda RZ signal) (of course the 200Hz pwm'ed signal is not a problem wth a 51 ...) with the following restrictions... only a 3V batt allowed and output must feed 0.5mA max ...
I was thinking about current sources and a 3state switch array (to draw current from +V to the output load, then the 'hiz' state with the load connected by itself to ground and then the -V state with the current flowing towards -V ... (i mean 3 0 -3V)
But i have some doubts about that solution and in the choice of the correct 3V regulator
(i'll upload the schematic of my idea as soon as i can )
best regards
Tuco!
I like sentences like: "of course the 200Hz pwm'ed signal is not a problem wth a 51..."
You talk about "the 200Hz" like we are expected to know something about it. We don't. We don't know anything besides the information you cover in your posts. We haven't seen your assignment specification.
