@ImpulseAdventure ImpulseAdventure released this Mar 1, 2018 · 21 commits to master since this release

Major changes since v0.9.2:

  • Enhancement: significant memory reduction for Arduino, extensive updates to handle GUI elements in Flash #32
  • Modify: streamline user configuration, split Arduino & LINUX
  • Add: support for nRF52
  • Add: support for m5stack
  • Add: support for PCD8544
  • Add: support for simple resistive touchscreen
  • Fix: Miscellaneous fixes

Migration notes:

  • Calls to many APIs may require search & replace for tsElem* to tsElemRef*. Many API calls that didn't previously include tsGui* will now require the addition of the GUI pointer as the first parameter.
  • GUIslice_config.h has now been replaced by two separate configurations, depending on the device platform (ie. GUIslice_config_ard.h and GUIslice_config_linux.h). The parameters within these configurations have changed in some cases, so one should update to the new defaults and then customize as required.
  • LINUX examples moved from /tests to /linux

Support Arduino debug output

      • Please refer to example code for details

Support elements in Flash memory

@ImpulseAdventure ImpulseAdventure released this Jan 4, 2017 · 214 commits to master since this release

  • Add: Significant RAM savings with Flash-based elements, making it possible to use smaller Arduino CPUs.
    • Add: Element collections support read-only elements stored in Flash memory (PROGMEM).
    • Add: Element Reference type defines where the elements are located (eg. tsPage's internal element array in RAM or external Flash memory).
    • Add: ElemCreate*_P() macros to build read-only elements in Flash
    • Change: Some Arduino sketches use ElemCreate*_P() macros to select Flash memory for elements, reducing RAM consumption considerably.
  • Change: Arduino sketches moved main loop code into loop()
  • Fix: Clipping of points fixed: ClipPt()
  • Change: Element drawing reduce flicker in frame: ElemDrawByRef()
  • Migration Notes (from 0.8.1):
    • Add an element reference array static/global (array of gslc_tsElemRef).
      • Previously, a static/global element array would have been allocated as follows:

        gslc_tsElem m_asPageElem[MAX_ELEM];
      • With this version, an element reference array must also be allocated. If Flash memory is not being used for elements, the array bounds can be the same as the element array. For example:

        gslc_tsElemRef m_asPageElemRef[MAX_ELEM];
      • See example code for details
    • PageAdd() adds two parameters (element reference array and total element count).
    • To take advantage of Flash-based elements, see example /arduino/gslc_ex07_ard/

UPDATE: As of commit 67f3a93 (2017/01/08), all CPUs (eg. Feather M0) can use ElemCreate*_P() macros (even if PROGMEM is not supported).
