Positron Pixel Foundry v1.00 introduced

  • Positron Pixel Foundry v1.00 (.NET 10 is no longer required) now replaces EPD2HexCompress, adding a wide range of new features.

v2.04

  • EPD module
    • Fixed bugs in EpdBmpFromCode() (buffered mode).
    • in Bitmap Sub causing corrupted white pixels or missing red/yellow content when both colors appeared in the same BWR/BWY image.
    • in EpdBmpRle Sub leaving stale color-plane data on non-colored pixels during the red/yellow decode pass.
    • in EpdBmpRle Sub a decode desync triggered when a compressed run ended exactly at a row boundary.
    • in EpdBmpRle Sub an off-by-one that could misalign the start of the next color plane.
  • EPD2HexCompress.exe - v2.01 a complete redesign, adding a wide range of new features.

v2.03

  • Added EPD module
  • Added hardware SPI support for newer PIC18-Q/K MCUs using different hardware register set 
  • Main library code optimization 
    • Modified TftReadDelay values
    • Replaced Color6bTo5b with right shift
    • Replaced Cos table with extended Sin table
  • Driver module
    • Fixed minor bug where forgot to add "bTftDriverSet = 1" in certain device drivers
    • Fixed a copy-paste bug in TftSetOrientation() for NV3007
  • Memory module
    • Optimization of code execution in Flash.inc                                                                      
    • Optimization of code execution in Memory.inc  
  • Touch module
    • Fixed memory overlapping bug causing inaccuracy with 3 point calibration and failure when more points are used
    • Touch Median16 now sorts independently for X and Y direction
    • Touch screen averaging now independent per axis
    • Touch screen point calculation now uses Q16.16 fixed point instead of the floating point math:

   Thus not compatible with previous version if calibration values were saved as floating point, 

if no stored values are pre-loaded, then use as before otherwise force user calibration after update.

      Note: fKX1 ... fKY3 from previous versions are no longer to be stored as calibration coefficients,

            instead use signed DWords: sdwKX1_FP, sdwKX2_FP, sdwKX3_FP, sdwKY1_FP, sdwKY2_FP, sdwKY3_FP
