- Updated Hot Air Gun cooling procedure
- Debug mode added allowing monitoring of the internal parameters
Apr 17 2020. New firmware release, 2.03. See detailed description on the project page.
- Two mode hardware switch supported: REED and TILT. Tilt switch algorithm updated.
- Fixed issue 'jammed on tip selection screen'. Now the main menu reacheble from tip selection mode by long press.
- Ambient temperature and tilt switch readings now are available on debug screen.
- Controller without soldering handle connected starts working in Hot Air Gun mode.
Apr 29 2020. New firmware release, 3.00. See detailed description on the project page.
- Optional 220v safety relay added.
- Rotary encoder acceleration deactivated.
May 12 2020. New firmware release, 3.01. See detailed description on the project page.
- Standby mode issues fixed.
- Temperature step feature added.
June 03 2020. New firmaware release, 3.02.
- Hot Air GUN start issue fixed. The power is supplied to the Hot Gun in 1 second after it activated allowing enabling AC relay.
- "About" menu item issue fixed. Now this menu is available.
- Tilt switch procedures reviewed and updated.
- The standby mode separated from main working mode and implemented as a new one.
- Screen saver timeout now is a single entity. It is no longer depended on mode switching. To return to the normal screen mode, touch the encoder.
- Software automatic power off procedure reviewed and updated. The controller can power off the iron in case of no tilt switch available.
- Accelerated mode of rotary encoder implemented in setting low power temperature procedure in the main menu.
Jan 03 2021. New firmware release, 4.00.
- Display initialization method chhanged. Now the rotation parameter is inside the contstuctor in display.cpp.
- Added support for 'Guarantee cool gun' feature. New feature requires the hardware to be updated. With new hardware schematics the controller guarantees the Hot Air Gun cooled before shutdown. You can put Hot Air Gun to the base then switch off the main power switch and leave your working place. The controller will switch-off the Hot Air Gun, waits till the Hot Air gun cooled and power-off itself. The new firmware release suports old hardware also. Of course, new 'guarantee cool gun feature' will not be available on old hardware.
Jan 30 2021. New hardware and firmware release, 4.01. The schematics with relay has been simplified.
- Support for 'Guarantee cool gun' feature changed. New feature requires the hardware to be updated. See stm32_T12+858D_v4.sch file in the eagle directory.
