serial connection
I have a question for the teams that are using the programming port to send data back and forth from another processor. You're probably using the external chip to offload some high bandwidth sampling or something like that. If you use the serial connection, then won't your sampling circuit still have to sit there waiting for the RC to acknowledge and transfer the data?
We're planning on using a second stamp 2sx and sending the data to the RC using the analog inputs. I can't see a way to use SERIN/SEROUT without creating a bottleneck, but any insight would be appreciated.
On another note, has anyone tried using one of the DAC chips to send data into the RC? We'd be taking an analog value, passing it through an ADC into the stamp, working on it, then converting it back to analog using a DAC on the other end.
