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 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
- If you have Nextion Editor v1.61.1 or higher you need to update your Tiva firmware to v3.1.0 or higher before you can update the Nextion firmware.
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.
- Multiple Nextion/TJC displays are supported. Chose the firmware according to your model number. If the Nextion version doesn't work, try the TJC version; some displays are not marked correctly. More infos in this forum post.
- 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...
- Nextion firmware versions 3.0.1 or higher are not compatible with Tiva firmwares lower than v3.0.1.
- Nextion and Tiva firmware versions 3.1.0 or higher are not compatible with any previous version.
- Nextion and Tiva firmware versions 4.0.0 or higher are not compatible with any previous version.
- Nextion and Tiva firmware versions 4.1.0-beta.5 or higher are not compatible with any previous version.
New features
- Dark Mode! You can enable/disable it under Settings->General.
- Help and Info page. Contains exactly what the name says.
- USB<->ESP/NXT passthrough. These modes replace the "NXT FW Upload". Instead of being focussed on the Nextion firmware upload protocoll, it is now a general passthrough/bridge mode. Anything on the Nextion (or ESP) UART gets mirrored to the USB UART. This allows not only firmware updates at any baud rate, but also debug communication with the Nextion screen or ESP8266 microcontroller. This allows btw. higher baud rates during the update. Check out the updated wiki page for more details!
