* Driver status
|
|
* 04/04/2002: Working driver
|
|
* 05/06/2002: Reading of return value
|
|
* 02/09/2002: KeyPad handeling and return string
|
|
* 03/09/2002: New icon incorporated
|
|
*
|
|
* THINGS NOT DONE:
|
|
* + No checking if right hardware is connected (firmware/hardware)
|
|
* + No BigNum (but screen is too small ???)
|
|
* + No support for multiple instance (require private structure)
|
|
* + No cache of custom char usage (like in MtxOrb)
|
|
*
|
|
* THINGS DONE:
|
|
* + Stopping the live reporting (of temperature)
|
|
* + Stopping the reporting of temp and fan (is it necessary after reboot)
|
|
* + Use of library for hbar and vbar (good but library could be better)
|
|
* + Support for keypad (Using a KeyRing)
|
|
*
|
|
* THINGS TO DO:
|
|
* + Make the caching at least for heartbeat icon
|
|
* + Create and use the library (for custom char handeling)
