Hello;
Learning through the arduino world; a basic question.
Let's say I have 4 pressure sensors; 10 times a second (@10hz) I want to log the data of the 4 sensors to a file on a sd card
#date #p1 #p2 #p3 #p4 .
From what I understand; only the mega is able to do this; because it has 4 hardware serial.
Is there a way to do simultaneous serial connections on a duemilanove.
NB;(I have looked at the newsoftserial library, but from what I understand this is not exactly what I need)
Regards,
Nico
First question is what sensors were you planning on using? Many sensors are addressable allowing you to have multiple device on one serial connection. Or if you haven't selected a particular sensor look for ones that allow this.
If the sensors have some sort of "handshake" line that lets you control when they send their readings, you could also use a multiplexer to switch a single serial line among them.
If they're designed to send data whenever they want to, you're pretty much stuck with a Mega, or adding something like the SC16IS752 to get some UARTs via I2C.
