<DIV><FONT face=Arial size=2>Popravde mate pravdu, take jsem si vsiml obrazku
c.50 z ktereho je videt, ze na portu P2.x je pouze PULL-UP odpor a odpor
vuci zemi chybi, ale zaroven se v datasheetu vychloubaji jak lze PWM vystupy
vyuzit (prepnout do modu) cituji "Dual NRZ 16-Bit Signa-Delta DAC", bez
jedine poznamky o nutnosti pouzit externi logiku, az jsem si rikal,
jses blbej a neco ti unika...</FONT></DIV>
<DIV><FONT face=Arial size=2>Asi vypustim PWM a pouziji nejaky
externi DAC, napriklad AD5324, ona presnost u PWM DAC je stejne veci
zahadnou.</FONT></DIV>

<DIV><FONT face=Arial size=2>To bych docela rad, ale tim MCU je ADuC84x a i
kdyz datasheet ma vice jak 100 stran tak udaj o tom jaky odpor ma vystup PWM
v log 0/1 se clovek nedocte. Celkove mam dojem, ze informace o PWM v techto
procesorech jsou vice nez strohe.</FONT></DIV></BLOCKQUOTE>
