    USART Manchester Encoding

      Reading through a lot of the LM3Sxxx documentation I can't seem to find anything implying that the on board 16C550 like USARTs have native hardware Manchester encoder modes like some older ARM (such as AT91SAM7x) with similar 16C550 like USARTs do.

      So I assume the USARTs in the LM3Sxxx series do not have this ability?

      If that is the case, are there any recommended techniques to generating a Manchester encoded data output solely within the LM3Sxxx devices?

      Thanks, Paul

      If you want just output the SSI module can be made to generate a pretty passable manchester code output with some lookup tables or a small bit of code.

      Just get the SSI to draw the waveform you want. With the FIFO's I would think you can put it out pretty fast too!

      I think on the Luminary Chips you could do it with just one pin used as the clock/ data in could still be programmed as GPIO.

      Good Luck with your project.
