GwInstek GDM-8341 Multimeter OSD & Control for Linux

gdm-8341 Multimeter OSD & Control for linux with keyboard mode selection

Requirements

You will require the SDL2 development lib in linux

The default (currently) linux kernel will not assign a /dev/ttyUSBx port to this meter without modifying cp210x.c to include the VID:PID pair and recompiling as a new kernel module. Hopefully this will be added in the future to the mainline kernel.

Because this meter locks the front panel during USB communications I have added keyboard controls for the common modes I use, continuity, volts, diode and resistance. Try win-alt-c/v/d/r respectively.

Setup

Build

(linux) make

Usage

Run from the command line

./gdm-8341-sdl -p /dev/ttyUSB0

Keyboard bindings

p : pause/unpause; use this for when you need to access the front panel
q : quit

(the following work anywhere in the X desktop, you do not have to be 'focused' on the app)
win-alt-v : change to volts mode
win-alt-r : change to resistance mode
win-alt-c : change to continuity mode
win-alt-d : change to diode mode
