Temperature display
The temperature variations can be monitored easily using the STM32 I2C SMBus feature.
This is managed by the SMBus Alert, which generates a dedicated interrupt informing the
system that the temperature is out of the selected range. This can be very useful when a
higher temperature needs an emergency action, as is the case in critical systems (motor
control, medical...).
If the temperature exceeds the high limit (TEMPERATURE_HIGH: High Limit Temperature),
the SMBus alert interrupt is generated and the warning message shown in
displayed on the LCD screen.
