Used environment

The highView Library Suite is developed in C++ and relies on objects.

Basic edition SDK

The Basic edition leverages the Arduino SDK as a hardware abstraction layer for the peripherals GPIO, UART, SPI and I²C, .

The Arduino SDK supports a large range of platforms and boards, including AVR, Cortex-M, Cortex-A, ESP32, MSP430, PIC32 and more.

Evaluation edition pre-compiled libraries

The pre-compiled libraries of the Evaluation edition are generated according to the Precompiled binaries procedure of the Library specifications page for Arduino CLI 0.26.

They are available for the following platforms and boards:

  • 32-bit Cortex-M0+ Raspberry Pi RP2040, with IDE Arduino 1.8.19 or 2.0.0 and boards package Pico RP2040 2.5.2;

  • 32-bits Espressif ESP32, with IDE Arduino 1.8.19 or 2.0.0 and boards package ESP32 2.0.4;

  • 32-bits Adafruit Feather nRF52840, with IDE Arduino 1.8.19 or 2.0.0 and boards package Adafruit nRF52 1.3.0.

Other platforms and boards may be available on request.

SDK-agnostic Commercial edition

However, the Commercial edition is SDK-agnostic and only requires standard C/C++ libraries. The peripherals library should be adapted accordingly.

Adaptations have been successfully tested against the following SDKs:

Externals tools

External tools have been tested on Linux Debian 11.4.

Version management

Each library has a release number to be checked at pre-processing.

Each library has its own release number.

#define hV_FONT_TERMINAL_RELEASE 503

The release number is checked at pre-processing.

#include "hV_Font_Terminal.h"
#if hV_FONT_TERMINAL_RELEASE < 504
#error Required hV_FONT_TERMINAL_RELEASE 504
#endif

In this example, if the hV_Font_Terminal library release is 503, the pre-processor expects 504 and prompts an error message:

#error Required hV_FONT_TERMINAL_RELEASE 504

highView library suite

The Pervasive Displays Library Suite relies on the highView library suite technologies.

The highView library suite provides a common high-level interface to drive multiple screen technologies, such as TFT, STN, OLED and e-paper, resistive and capacitive touch, and enhanced haptic feed-back.

The suite leverages objects for modular design, focuses on light footprint for memory and processing, and ensures compatibility with previous iterations of the suite.
