A low-cost multichannel data-acquisition system based on the Commodore C-64 or the C-128 microcomputer is described. The hardware supports up to 16 input channels at 13-bit resolution. The sampling rate of the analog-to-digital converter is 25/s. Features of the supporting software include both numeric and multicolor graphic screen output, printer output with user’s comments, and disk storage of the digitized signals. The graphic display has a 320×200-pixel grid and can be displayed in 16 colors. Input readings may be scheduled using the internal computer clock for data collection over an extended period. Easy construction using low-cost components makes this an attractive laboratory data-acquisition system.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
