dymoscale

Go library for reading Dymo USB postal scales.

You can buy them relatively cheap from Ebay.

Tested with a Dymo M5, but will probably work with other models too.

Developing

darwin/amd64

To test and build on Darwin.

brew install libusb
make darwin

You may get an access denied error though when using the binary/library because of [this problem][libusb_osx] with OS X attaching its HID driver.

[libusb_osx]: https://github.com/libusb/libusb/wiki/FAQ#How_can_I_run_libusb_applications_under_Mac_OS_X_if_there_is_already_a_kernel_extension_installed_for_the_device)

linux/amd64

To test, build, and run on Linux in Docker:

make docker
make
./dymodump/dymodump

linux/arm

To test and cross-compile to ARM, which can run on a Raspberry Pi:

make docker
make test arm
