Emy Firmware - Speech synthesizers

This firmware is designed for Emy 2019 edition (PCB revision 1.0c).

It can run on the Emy 2018 (PCB revision 1.0b) version, but the USB keyboard functionality will not work unless you modify it by following these instructions

Firmware load

Option 1 Saving the firmware exactly as “firmware.bin” on the SD card and restart

Option 2 ( requires the Emy version 2.1 or bigger to be installed first)
Save it on the SD card with a name like “emy.bin” and you will be able to load it from the code>flasher menu.
The same applies to the Mea, Kaiwa, Sino & Vax firmware, so you can switch from one to another within the main menu

This function simply copies the firmware to “firmware.bin” and reboots the system while deleting the firmware.bin but keeping the original with its name.
