Hi to all, Some note to the ADC on 16F690. This evening i've playing with my code for the 16F690, I've experimentig with clock, ranging from 8Mhz to 125Khz. The DS of 16F690 at page 109 has a nice table for FOSC/?? it seems that FOSC/16 can handle all the frequency range from 125khz to 8Mhz, at least on my test set (LPC with LCD attached on portC) it works. At page 111 there is a list of action to take to make ADC work, I followed it and explained explicitly in the code and it works. I'm guessing a way to assign the input pin in the library but I'm thinking it's better to assign it in the code, together with ANSEL settings too, but Sebastien could give me an advice. The 16F690 has only the selection on VDD or external VREF trough pin RA1 for the reference voltage and seem it can trough CHS bit in ADCON0 select an internal reference of 0,6 volt and a CVREF for the conversion, (I didn't undestand very well the DS on this point).
PS (Not for Rob and Sebastien that I bothered with PM) my code for 16F690 is on Jallist at http://tech.groups.yahoo.com/group/jallist/files/CarloD/ That's all for now.
