Measure Bias submenu

If the joystick push-button has been pressed, the MCU exits the Measure Bias submenu and

the message shown in Figure 56 is displayed on the LCD screen.

If the SEL push-button has been pressed, the MCU starts the Measure Bias submenu and

Measure Bias Mode (Procedure Start) submenu

Once the joystick push-button has been pressed, the MCU enters the Stop mode and waits

for the rising edge on PA0, that can be generated by the external counter, to exit the MCU

from Stop mode.

When the external rising edge is generated on PA0, the MCU exits the Stop mode, the

STM32L message is displayed on the LCD Glass and the message shown in Figure 59 is

displayed on the LCD screen.
