GG Meter Datalogging
Well I started writing some of the routines to dump SCI data out of the serial port on the GG Meter. It was a pretty easy task. I through together a little log file to test out its speed. At 19,200bps I was acheiving about 142 samples per second almost as fast as my Analog to Digital converter was running. After bumping the speed up to 115,200 I can see litteraly every sample my Analog converter is running at as the data can be transmissited out of SCI before the next sample is ready roughly 188 samples per second. Granted this was with a single channel only but there was an extrodinary amount of fluff. I was using 4 bytes to transmit one 12 bit number out in hexidecimal text format. I could easily fit 2 12 bit numbers in 4 bytes (actually in 3 if I was really cool).
