Thanks for the reply. All information is useful. How much memory did you = add? I have not worked with SPI before so I want to try it with memory and = a 24-bit A/D. ----- Original Message ----- = From: "Peter Feucht" To: "'Microcontroller discussion list - Public.'"

Hi, Rich, I attached an external memory (Flash 25PE80) to an 24H128GP206, but I never used the internal SPI module because it appeared somewhat "cloudy" to me, so I wrote some very basic routines in BASIC, to do the communication.
