Installation
- Tiva Flash utilities and drivers can be found in the repository under Tiva_Flash_Utilities
- To update the Nextion firmware over USB you need at least firmware v2.0-beta-1 and the Nextion Editor. On the Syntherrupter, go to Settings->USB FW Update. Connect the Syntherrupter to your PC. More infos about updating the Nextion firmware with the Nextion Editor can be found in their documentation, chapter 2.1 and chapter 4
Notes
- Since the amount of coils that can be controlled by the Syntherrupter has to be set at compile time I attached Tiva binaries for 1-6 coils.
- If you flash the Tiva for the first time or increase the coil number always check ALL settings. You should check it after each update, too. Just in case...
- Sound quality is directly affected by the number of coils. Therefore you shouldn't flash a firmware with more coils than absolutely necessary. Remember, you can reflash at any time. To improve sound quality when not all outputs are active, make sure all of the inactive outputs have no MIDI channels assigned.
- Nextion firmware versions 3.0.1 or higher are not compatible with Tiva firmware lower than v3.0.1.
Small changes
- Outputs didn't turn off when leaving simple mode
- Coil 6 ontime limit was always equal to coil 1 limit
- User 2 settings didn't change until reboot when coil limits were modified (User 2 ontime and duty settings are normally equal to the highest coil limits).
- When confirming a settings change with "OK" or by selecting another value, a sanity check is done. This was missing when leaving the page (=> it was possible to enter one nonsense value and it would not be detected).
- Slight adjustments to the ADSR curves. Program 7 does no more turn off completely on long notes but stays at a low value.
- Some spit 'n polishing
