------------------------------------------------------------------------------- MTK3339 GPS NMEA UART output ------------------------------------------------------------------------------- This is a dump of NMEA data from MTK3339 GPS Adafruit Breakout's UART output. For details see: http://www.adafruit.com/products/746 http://www.adafruit.com/datasheets/GlobalTop-FGPMMOPA6H-Datasheet-V0A.pdf Logic analyzer setup -------------------- The logic anlyzer used was a Open Logic Sniffer at a sample rate of 200KHz for using a baud rate of 9600 8N1. Probe UART ---------------- 0 TX Data ---- The sigrok command line used was: sigrok-cli --driver=ols:conn=/dev/ttyACM0 --config rle=1:samplerate= \ --samples=1000000 -p '0=TX' --triggers 'TX=0' -o .sr Device only sent 845282 samples. We capture as many samples as the RLE mode can handle.
