CC6H C Compiler

  • Supports Holtek HT microcontrollers
  • Compact code
  • CC5X compatibility


The planned compiler inherits the code efficiency and features from CC5X, including multitasking support.

Current main limitations:
1) ASM file only (Holtek assembler is currently required to generate HEX file after compilation using generated ASM as input).
2) HT devices using banking of RAM (and code) by setting the BP register are not supported.


Beta versions are available. The further schedule is not defined.

Demo Edition

The downloadable packages contains example code and txt files. The compiler is a 32 bit console application that can be started from the command line and from many IDE applications.

Up to 8k words of code can be generated, but NO hex file. The assembly file is MODIFIED (labels are not complete). This TEST edition supports 8, 16, 24 and 32 bit integers, fixed and floating point math, leanslice multitasking and FULL optimization (same as EXTENDED edition). This allows code development and conversion of existing applications to check code size.

Download the file by using the right mouse button (browser dependent), and select Save Link As or Save Target As to save the file. Then start or unzip it.

cc6htest.exe (~800k) - Windows installation program
(~250k)  - ZIP file alternative (manual installation)
