2. Oct. 2006 - Version 0.81
|

12. Apr. 2008 - Version 0.83
|
||||
|
||||
* Bernhard Roth reported a mistake in the UART-configuration
|
||||
for double-speed. Thanks for the report.
|
||||
Change in main.c:
|
||||
UART_STATUS = UART_DOUBLE; -> UART_STATUS = (1<<UART_DOUBLE);
|
||||
* Added definitions for ATmega644P and ATmega324P
|
||||
* Tested with ATmega324P, gcc 4.2.2, avr-libc 1.4.6
|
||||
* Added testapp to verify "exit bootloader" with
|
||||
watchdog (n.b.: watchdog-disable called early in testapp)
|
||||
|
||||
27. Jan. 2007 - Version 0.82
|
||||
|
||||
* Added definitions for ATmega644.
|
||||
* Using avr-lib's eeprom-functions (old "direct-access"-code
|
||||
has not been compatible with ATmega644).
|
||||
* Watchdog-disable at startup (configurable): avoids problems with
|
||||
repeated login to bootloader. Not needed if the bootloader is
|
||||
never re-entered again between an "exit programming" and
|
||||
a system-reset/power-toogle.
|
||||
* Additional watchdog disable-function for ATmega644.
|
||||
* Made watchdog-enable time at exit-programming a configuration-value
|
||||
(define).
|
||||
* Bootloader read-protection: if enabled the bootloader fakes
|
||||
an empty boot-section (configurable by define)
|
||||
Since more of the avr-libc functions's are used this version
|
||||
should be more portable for other AVRs but the size of the
|
||||
binary increases a little bit.
|
||||
Make sure to disable the watchdog early in the user-application
|
||||
esp. when using a "modern" AVR (i.e. ATmega48/88/168/644/324P/644P).
|
||||
|
||||
3. Dec. 2006 - Version 0.81
|
||||
|
||||
* Added definitions for ATmega162.
|
||||
* Fixed init for double-speed (bitmask). Thanks to Bernhard Roth
|
||||

||||
