Wismec Presa TC75W Test Results

[AndydeCleyre]

Thanks!

I'm on Arch Linux and installed via the python-evic-git PKGBUILD in the AUR.

Plugged in, ran evic-usb dump-dataflash -o out.bin:

Finding device...OK
        Manufacturer: Nuvoton
        Product: HID Transfer
        Serial No: A02014090304

Reading data flash...OK
        Device name: Presa TC75W
        Firmware version: 3.00
        Hardware version: 1.01

Writing data flash to the file...OK

Success!

Ran evic-usb upload Presa_TC75W_V4.03.bin:

        Manufacturer: Nuvoton
        Product: HID Transfer
        Serial No: A02014090304

The screen on the device seemed distorted, but that may just be the new style. I tried evic-usb screenshot -o screenshot.png, but it just hung after

Finding device...OK

Thanks again for enabling me to easily flash this without Windows!

How did you do that? I've got following error while trying to dump flash using latest master:

I experienced the same. The python-evic cli.py and device.py code does not conform to the current python hid interface, hence the attribute error. It could be that the current master was intended for a different version of hid, but I haven't verified that.

This fork of Ban3/python-evic contains the necessary fixes to get you up and running: https://github.com/artisan-digital/python-evic
