Hi everybody, Well iam new to this forum and hope to get help from 'experts'here! Iam doing my Thesis on Microcontroller based Maximum Power Point Tracker for Solar PV. As iam not expert in embedded,but i know programming in 8051.In the same project i have to take voltage and current from solar panel at the same time and have to multiply(and many more operation) and also i need to have signal from the battery.For all this i need atlist 4 ADC.So i decided to use ADC0808. My question is that:can i get same instant data(voltage and current) or i get data one by one from ADC. Since the problem of external ADC will b not there if i use PIC or AVR,but i dont have idea of programming on same.So please if anybody have idea about same then please share with me. Thankx.
You get them one at a time. The same is ture with the builtin ones in the PIC and the AVR. And 8051 based chips with built in A/D are the same. I do not think that few millisecond offset will affect you application.
use sample and hold, do all holds at the same time
