Front board version detection

New:

• The firmware now checks for connection between pin 53 and pin 54 of the MCU in order to detect if newer revision front PCB is used.

Note:

• This version still does not support tip-change function. It will be published in future version

Display detection, cold junction sensor reading

New

• Controller is now able to read cold junction sensor in the iron, if present (currently made on PACE TD100/TD200)
• Display detection is changed - SH1106 users must install resistor between CS and GND
• The project can also be compiled with latest XC32 (2.50) with legacy peripheral libraries installed

Bug fixes, new features.

New:

• Bouncing stand-by text
• Displays "HOT" when in stand-by and iron temperature is > 60 C
• Instruments starts at 1/4 power and ramp up when needed (was opposite)
• Revised power selection algorithm
• Added "Instrument information" option in the menu
• Instrument ID now displayed in HEX
• One more digit for resistance in Calibration screen
• When in calibration, controller does not search for instrument, and now the SENSEA and SENSEB currents are constant and can be measured with multimeter
• Updated bootloader to detect SH1106 display controller

Bugfixes:

• Stand-by screen now displays normal
• No overshoot on JBC C210 and considerably reduced on JBC Microtweezers

Deislpay detection. Corrected iron profiles.

New:

• Detection of SSD1306/SH1106 display controller.

Bugfixes:

• Revised all JBC, all PACE, and HAKKO T15 profiles due to malfunction in my controller's current sources.
