&lt;i&gt;i will do it all in C.&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
No, you won&amp;#39;t. C doesn&amp;#39;t generate current of any kind.&lt;/p&gt;

&lt;p&gt;
&lt;i&gt;can be keil board.&lt;/i&gt;&lt;/p&gt;

&lt;p&gt;
Aha. And which of roughly a dozen of those are you talking
about?&lt;/p&gt;

&lt;p&gt;
And what the heck does that requirment of 5 pins have to do with
anything?&lt;/p&gt;

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.&lt;/p&gt;

&lt;p&gt;
all answers will be read and plz dont be hidden.&lt;/p&gt;

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?&lt;/p&gt;

&lt;p&gt;
I just fail to see how you considered this to be a suitable forum
for discussing a hardware implementation of a 20mA current
source.&lt;/p&gt;
