One installer for every Morserino — it recognises which one you plugged in.
This one page installs the firmware for the classic Morserino-32 and for the M32 Pocket — including the Pocket's Accessibility Edition, which speaks its menus aloud. You no longer have to know which page to start on: connect the device and it works out the rest.
You need a browser that supports the Web Serial API, like current versions of Chrome, Edge, Opera or Firefox on desktop PCs, and a USB cable fit for data transfer, not just for charging.
Owners of a classic Morserino-32 (1st and 2nd edition) also need the driver for the Silicon Labs CP210x USB to serial device.
After clicking Connect, a pop-up appears — select the correct USB port there.
This is what is connected right now.
Do not disconnect the device until this finishes.
Starting…
Connect first. The file is written as-is at the address you give — nothing else on the device is touched.
