The soldering iron controller built on stm32 micro controller. AC6 - STM32 System Workbench & CubeMX software development tools have been used to bult the project. Project page: https://www.hackster.io/sfrwmaker/soldering-iron-controller-for-hakko-t12-tips-on-stm32-c50ccc
Revision history
01/15/2020
- Now tip activation menu is avalable in tip selection mode, you need long press the encoder
- Debug verion is avaliable. In this firmware the internal information is shown on the display as following:
- P T
-
C - (i-t) A, where P - is the applied power (rotate the encoder to change this value) T - is the IRON temperature C - is the current through the IRON A - is the ambient temperature "i" means the controller assumes the IRON is connected "t" means the tilt switch is active (IRON is in use)
01/11/2020
- The schematics changed
- Buzzer is always on issue fixed
- Screen saver feature implemented
- New encoder button procedure increase the management stability
11/16/2019
- Fixed incorrect message processing issue. Now "EEPROM read error" message would be displayed in case if the controller cannot access EEPROM IC.
- Empty slot for TIP calibration data issue fixed. The slot of non-active tip can be used for newly activated tip. When new tip activated, the controller checks data written to EEPROM.
- If tip configuration data would not read correctly the "EEPROM write error" message would be displayed.
11/09/2019
- Tip connection issue has been fixed.
- Capacitor C8 has been removed from schematics.
11/05/2019
- New Encoder algorithm implemented, just press and hold the encoder button for long press
- EEPROM scheking procedure implemented, two error messages added
- Several issues fixed including:
- default tip calibration data issue
- automatic adjustment of the tip temperature depending on the ambient temperature issue
10/21/2019
- Fixed i2c type display initialization
10/15/2019
- Fixed incorrenct ambient temperature readings when power is on
10/10/2019 New controller version released, v2.00.
- Simplified schematic implemented
- New powering algorithm implemented
- OLED displays with SPI or I2C interface are supported
- PWM frequency decreased to 20HZ
- The project migrated to c++
- All procedures were revisited
- u8g2 library used in the project
- Previous release has been moved to v.100 folder See detailed description on hacsters.io site
22/10 2018 (v1.00)
- Eeprom size error fixed
- New schema of saving tip data to the eeprom implemented.
- Now only active tips are placed to the eeprom. It is possible to ad new tip to the tip list.
- New calibration procedure implemented
- Minor bug fixed
01/04/2019 (v1.00)
- Tilt switch implemented
