 Instead of stcgal, you could alternatively use the official stc-isp tool, e.g stc-isp-15xx-v6.85I.exe, to flash.
 A windows app, but also works fine for me under mac and linux with wine.

-**note** due to optimizations that make use of "eeprom" section for holding lookup tables, if you are using 4k flash model mcu AND if using stc-isp tool, you must flash main.hex (as code file) and eeprom.hex (as eeprom file). (Ignore stc-isp warning about exceeding space when loading code file.)

 To generate eeprom.hex, run:
 ```
 make eeprom

 ## clock assumptions
 For STC15F204EA, some of the code assumes 11.0592 MHz internal RC system clock (set by stc-isp or stcgal).
