#173798 - You don't really need a dedicated chip Responding to: ???'s previous message |
The LSI chip is nice, but is mainly used for high end data acquisition systems or high end servo control. One could use a simple 8052 to figure it out, as well. The LSI chip is nice in the fact that it can give you up to 4 times the resolution of your encoder and can out do an MCU in speed. A nice doc http://www.bipom.com/applicati...ncoder.pdf and the associated program to do it from BASIC but can be ported http://www.bipom.com/applicati...ncoder.zip |
