ATTINY and serial comms problem

Other Hardware 3rd Party Boards

Hi,
I want to do something fairly simple: to measure a voltage every 10 minutes for around 5 hours.
I have already done this using a standalone 328 via an RS232 link using a MAX232.
Is it feasible to do this using the simpler ATTINY45? This has an A/D, but can it also
send/receive data via an RS232? I have read and re-read the Arduino info about Software
Serial, but I cant make sense of it.

You could use SoftwareSeial or TinyDebugSerial

An example using TinyDebugSerial. It will output on pin PB3 of an Attiny45

void setup() {
Serial.begin(9600);
}

void loop() {
 Serial.println("Testing..");

}
