AJB2K3 Posted July 8, 2004 Report Share Posted July 8, 2004 for the rs232 stage you may want to look into UART's and MAX 3222 Quote Link to comment Share on other sites More sharing options...

Kevin Weddle Posted July 9, 2004 Report Share Posted July 9, 2004 Keeping it simple is the phrase that sticks out here. Many times the technology has come to a point that exceeds the ability of the novice to configure it to his liking. The best way to go about a solution is to use the most primitive devices. You might be surprised that you can effectively produce results when you cut out the fat. The PC makes this task easy by using simple protocals. Remember, the purpose of communication is to send the data at a rate that is compatible while making use of the mean time. This means that other things can be accomplished while you wait. This is the difference between serial and parallel communication. Quote Link to comment Share on other sites More sharing options...
