Function Documentation

◆ user_button_pressed()

def LAB_0x04_main.user_button_pressed ( IRQ_source )

Callback which runs when the user presses the blue input button on the Nucleo.

This function is triggered when the Nucleo's onboard button is pressed. It records the reaction timer count, indexes the number of presses, and check to see if the button was pressed early.

Parameters

IRQ_source The source of the interrupt. This must be taken as an arg, but is not used

Variable Documentation

◆ amb_temp

LAB_0x04_main.amb_temp = temp_sensor.celcius()

The ambient temperature read by the MCP9808 sensor in C.

◆ board_LED

LAB_0x04_main.board_LED = pyb.Pin(pyb.Pin.cpu.A5, mode=pyb.Pin.OUT)

A pin object bound to the board Led (Pin A5)

◆ core_sensor

LAB_0x04_main.core_sensor = pyb.ADCAll(12, 0x70000)

The ADCALL object used to measure the Nucleo's core temperature.

◆ core_temp

LAB_0x04_main.core_temp = core_sensor.read_core_temp()

The Nucleo's core temperature in C.

◆ cur_time

LAB_0x04_main.cur_time = utime.ticks_ms()

◆ el_time

LAB_0x04_main.el_time = utime.ticks_diff(cur_time,start_time)

◆ extint

LAB_0x04_main.extint = pyb.ExtInt(user_button,pyb.ExtInt.IRQ_FALLING,pyb.Pin.PULL_NONE,user_button_pressed)

The callback for the user button.

Activation occurs on a falling edge.

◆ i2c

LAB_0x04_main.i2c = I2C(1, I2C.MASTER)

The pyb.I2C object used to communicate with the MCP9808 sensor.

The communication channel is opened on bus 1, and the Nucleo is designated as the master.

◆ PRESS

int LAB_0x04_main.PRESS = 0

A boolean indicating if the user button has been pressed.

◆ Press

bool LAB_0x04_main.Press = False

◆ start_time

LAB_0x04_main.start_time = utime.ticks_ms()

The starting timestamp for the temperature recording program.

◆ temp_sensor

LAB_0x04_main.temp_sensor = MCP9808(i2c,0)

The mcp9808 object connected to the external temperature sensor.

◆ user_button

LAB_0x04_main.user_button = pyb.Pin(pyb.Pin.cpu.C13, mode=pyb.Pin.IN)

A pin object bound to the user button (Pin PC13)

◆ vref

LAB_0x04_main.vref = core_sensor.read_core_vref()

The Nucelo's reference voltage.
