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. Coil - pin association:
- Coil 1: PD0
- Coil 2: PD2
- Coil 3: PM0
- Coil 4: PM2
- Coil 5: PM4
- Coil 6: PM6
- 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.
- The Nextion v3.0.1 firmware is not compatible with previous Tiva firmwares.
Big changes
- Better handling of incoming MIDI data. The improved efficiency removed almost all of the jitter compared to v3.0.0.
- Again, because of the better efficiency it is now possible to play up 8 notes per coil.
- You may want to look at the v3.0.0 release notes.
Small changes
- A warning will be displayed if no valid config was found in the EEPROM.
- In previous releases with only one coil it was not possible to assign MIDI channels from the MIDI page since the button was missing. This is now fixed.
- Some general bugfixes and tweaks.
