HiPi Modules 0.72 Released

Currently it seems I'm exploring different ways of displaying information on a headless pie.
Some day, I hope to build something with nixie tubes.

Until then, this LED matrix pHAT from Pimoroni is the most fun display I've tinkered with in a while.

A retro display driven by Perl.  HiPi 0.72  contains HiPi::Interface::MicroDotPHAT - a Perl port of the supplier's Python library.

HiPi Modules 0.71 Released

The latest release of HiPi includes support for some common small form factor E-Paper displays.

Several displays from Waveshare are supported along with the Inky pHAT from Pimoroni.


Given the slow refresh time of many of these displays and the long recommended intervals between refreshes, potential application is  is limited. However, they look great if their limitations are not a  problem in your use case.

Module HiPi::Interface::EPaper wraps the support.


Also included in this release are HiPi::Interface::TMP102 which wraps access to the TMP102 I2C temperature sensor breakout and HiPi::Interface::MS5611 which provides a wrapper for the I2C interface to the MS5611 barometric pressure and temperature sensor.
