Module13.2 PPS

Example

Continuously read and print the output current, output voltage and MCU temperature (via serial port)

from m5stack import *
from m5stack_ui import *
from uiflow import *
import module

screen = M5Screen()
screen.clean_screen()
screen.set_screen_bg_color(0xFFFFFF)

pps = module.get(module.PPS)

pps.init_i2c_address(0x35)
pps.setOutput(True)
pps.setOutputVoltage(5.5)
pps.setOutputCurrent(1)
while True:
  print((str('output current:') + str((pps.readOutputCurrent()))))
  print((str('output voltage:') + str((pps.readOutputVoltage()))))
  print((str('MCU temperature:') + str((pps.readMcuTemperature()))))
  wait_ms(2)

API

pps.getI2CAddress()

• Get the current device's I2C address

pps.init_i2c_address(0x35)

• Initialize the device's I2C address

pps.readDataUpdateFlag()

• Get the data update flag, returns an integer. This flag is usually used to indicate whether the data has been updated

pps.readInputVoltage()

• Get the input voltage value in volts (V), returns a float. This value represents the currently measured input voltage

pps.readMcuTemperature()

• Get the MCU temperature value in degrees Celsius (°C), returns a float. This value represents the currently measured microcontroller temperature

pps.readModuleId()

• Get the module ID, returns an integer. This ID is used to uniquely identify the device or module

pps.readOutputCurrent()

• Get the output current value in amperes (A), returns a float. This value represents the currently measured output current

pps.readOutputVoltage()

• Get the output voltage value in volts (V), returns a float. This value represents the currently measured output voltage

pps.readPsuRunningMode()

• Get the power module's running mode, returns an integer. This is usually used to indicate the current operating status of the power module

pps.readUID()

• Get the unique identifier (UID), returns a byte array. The UID is used to uniquely identify the device or module

pps.setI2CAddress()

• Set the device's I2C address

pps.setOutput(True)

• Set the output state. This function is usually used to control the device's output, such as turning a feature or module on or off

pps.setOutputCurrent(1)

• Set the output current, range is 0 to 5 amperes. This is used to control the device's output current

pps.setOutputVoltage(5.5)

• Set the device's output voltage. The range is 0 to 30 volts, used to adjust the device's output voltage value, controlling power supply or voltage level
