rs232 dac

I have a , in text format, table like following

time mSek | voltage (mV)
-------------------------------
0.000 0.9
0.001 1.2
0.002 1.1
0.000 0.4

I wanna play this data in its original as input to a D/A chip. Output is the analog waveform. I'll transmit the data between computer to this DAC usgin rs-232.

thanks, how I can do it?
 

rs232 to dac

You could use a uC to read the serial port, and load the DAC with data received.

uC means microcontroller, like PIC or AVR, or other... so many.

The uC reads the RS232, and converts the data to apply to the DAC.

The DAC outputs the analogue value you transmitted in RS232 text.

altogheter i donk think so, but you can find a uC working with RS232, and uC working with DAC.

Its your choice now what to do !!

Either one of them would be fine. I can't seem to find one example. Again I am totally beginner. I do not know where to start.

Am I looking too ambitious to produce analog from a simple text table with voltage/time generated on an EDA application?
