Thanks to your effort,

My herware engineer disigned pins PA8 and PA9 to be analog aoutput in range of 4-20mA, can i execute an analog signal through those pins? if yes how can i do it? Thank again.

Hi,

DAC peripheral in High density devices is able to output analog signals with dedicated pins. Cheers, STOne-32. [ This message was edited by: STOne-32 on 29-10-2008 12:48 ]

If he designed it, then your hardware engineer should be able to tell you how to use it!

May be he considered using PWM from timer 1. There should be also a low-pass filter.
