2.50

Voltages:

• Display "---" when measurements are invalid or out of range.
• Display "not" when VREG is not available because VIN voltage is below 6V.
• Improved voltage measurement and calibration algorithms.
• Stop at limit values when holding +,- keys to change DAC or VREG.

Serial:

• Added LabBoard Serial control protocol.
• Added background serial mode.
• Added Serial pin swapping to select LabBoard control from PC or Arduino.
• Exiting serial mode requires + or - key to be pressed. Allows to use other keys freely.
• Removed serial wiring check for 2.1, 2.2 boards.
• Changed serial mode TX pin from TXD to SWCLK. This allows to use pulse generator in serial mode. RX is still at DIG2.

Pulse generator:

• In pulse mode DIG2 LED displays output state of TXD.
• Improved number input method in Pulse and AD9833 modes.
• Improve Pulse generator mode user interface. Added Frequency (Hz) and duty cycle settings.

Modes:

• Added AD9833 mode.

Other:

• Change display brightness range from -7-8 to 0-15.
