hey m8. my task is to do the 20mA curret source but how! it must be 5 pins. is the adc good or the dac better? what timer can i use? t0 or t1 or t2? can anyone me quick plz.
Are you going to implement it in software? Using any of the Keil compilers? Or did you plan to redesign one of the Keil processor boards?
I just fail to see how you considered this to be a suitable forum for discussing a hardware implementation of a 20mA current source.
this is the meat m8. i will do it all in C. can be keil board. it will have buttons to choose the current (ie 10 15 20 25 30 35 40 45 50 53 etc). the buttons will have numbers and the current will be displayed in a box.
all answers will be read and plz dont be hidden.
i will do it all in C.
No, you won't. C doesn't generate current of any kind.
can be keil board.
Aha. And which of roughly a dozen of those are you talking about?
And what the heck does that requirment of 5 pins have to do with anything?
