Perl Modules for Raspberry Pi
Version 0.90 - released 11 November 2023

HiPi Perl Modules

The HiPi Modules provide access to the Raspberry Pi for your Perl scripts.

The distribution contains modules that allow you to access the Raspberry Pi GPIO pins directly and modules that wrap access to the kernel device drivers for the GPIO, SPI, I2C and 1 Wire devices.

The distribution also provides high level wrappers for some common ICs and peripherals:

  • MCP3nnn SPI analogue to digital converter series
  • MCP4nnn SPI digital to analogue converter series
  • MCP23017 I2C and MCP23S17 SPI GPIO extenders
  • PCF8574 I2C 8 bit GPIO extender
  • Maxim 18S20 and 18B20 1 Wire temperature sensors
  • Freescale MPL3115A2 pressure and temperature sensor
  • Commands to control Energenie switches and adaptors
  • PCA9685 I2C 16-channel PWM / Servo Controller
  • PCA9544A I2C Multiplexer
  • SSD1306 and SH1106 based OLED displays
  • MS5611 pressure and temperature sensor
  • TMP102 temperature sensor
  • BMP280 temperature and pressure sensor
  • BME280 temperature, pressure and humidity sensor
  • MAX7129 LED driver and matrix strips
  • H44780 based LCD backpacks from HobbyTronics (I2C/Serial), SparkFun (Serial) and generic I2C boards based on the PCF8574.
  • Several E-Paper or E-Ink displays.

The modules are designed for the standard distributions of Raspberry Pi OS.
