Usage Examples

Auto-Connect

import pygmc

gc = pygmc.connect()

ver = gc.get_version()
print(ver)

cpm = gc.get_cpm()
print(cpm)

Under the hood, pygmc searches through all available USB ports (dev devices, com). For each port it will try to connect with the highest baudrate and check if the device can communicate. It will attempt every baudrate. It sends a <GETVER>> command and checks if the output is in the list of expected devices. The first successful device is used.

Connect With Exact Port

import pygmc

gc = pygmc.connect(port="/dev/ttyUSB0")

ver = gc.get_version()
print(ver)

cpm = gc.get_cpm()
print(cpm)

Under the hood, pygmc will connect to that exact port/dev-device/com and attempt to communicate with different baudrates until it gets a successful response.
