OK, and how can I know if the propeller work well and is not damaged ? I got these voltages :
P0 to P27 : 0,03v
P9 (vss) : 3v
P31 : 0,06v
P30 : 0,3v
P29 : 3,4v
P28 : 3,4v
On Yours last SCH's I can't see any RESET system.
And without that You can only communicate with Programs that use serial communication BUT not Identify Propeller else program it From Any Tool's.
Regards

ah, ok ^^, and how can I test if the propeller work ? Which command have I to do in the terminal ? and how to connect the reset to the serial adapter ?

re "I just test it with the propeller tool and tried an identification of the prop"
and....
did it work?
I think you are very close to getting this working, but there are so many little steps along the way and each one has to be perfect. For a quick test, can you program (or identify) a propeller through your max3222 circuit? That tests a lot of things - the max circuit, the Rx and Tx lines and the reset circuit. Any chance of a quick photo of what you have wired up so far?
Damn it ! I finally did the serial to ttl with two 2N3904 and a 3906 ... and it does not work I suspect the propeller to be dead, I can't see an other reason, do you know how I can test the propeller in order to see if it work ?

P31 : 0,06v
P30 : 0,3v
P29 : 3,4v

And when the max3222 is connected, P31 go to 3,5v
How are you testing the RS-232 output from the MAX3222?
