Today i would appreciate any help telling me where i can find sample routines or source code to use the analog to digital converter inside the 17c7xx family. I already read all the literature in the datasheet (30289a) and reviewed the code. I am using polling to know when a conversion is ready and then i am writing the value in ports c and d. But i don=B4t see any change in ports c and d when i vary the analog input from 0 to 3 volts. The conversion clock is set to Fosc/32. I am also waiting as much as 200uS to hit the initial go signal, but even though i can assure the code is running one conversion after the other, because of a flag in port E, the value on ports c and d stays fixed. --------------5925378B9B74FD4CB6C3C6A6 Content-Type: text/x-vcard; charset=us-ascii; name="promero.vcf" Content-Description: Card for promero Content-Disposition: attachment; filename="promero.vcf" Content-Transfer-Encoding: quoted-printable X-MIME-Autoconverted: from 8bit to quoted-printable by silena.insitel.com.co id RAA26711 begin:vcard=20 n:Romero Plaza;P=E1vel Ernesto tel;cell:5489528 tel;fax:6-7444829 tel;home:6-7464233 tel;work:6-7444829 x-mozilla-html:TRUE url:www.insitel.com.co org:Insitel Ltda.;Research & Development adr:;;Calle 21 # 16 - 46 Piso 7;Armenia;Quind=EDo;;Colombia version:2.1 email;internet:promero@insitel.com.co title:Hardware Engineer fn:P=E1vel Ernesto Romero Plaza end:vcard --------------5925378B9B74FD4CB6C3C6A6-- -- http://www.piclist.com hint: The PICList is archived three different ways.
