I am not sure what you are trying to do, but you appear to have the right idea for setting up the baudrate divisor. This line will set up both UBBRH and UBBRL using their 16-bit...

Bootloader updating itself
I don't think you can change the fuse bits for bootsize under software control from the 'inside'. I could be wrong, but looking at the manual just now, I don't see how yet.

jtagice+stk500 on digikey for $150
I guess we just have to sit tight and pretty soon there'll be an STK500, JTAGIce_II and Dragon package. Then we'll have all programming modes covered, high-voltage, ISP and JTAG...

Forgetful EEPROM
Interesting Signature Values! They all have bit 6 set high, whether it should be or not, yep, sounds like your STK500 may well be stuffed! Sorry.

[TUT] [C] GCC and the PROGMEM Attribute
The strncmp_P() call is missing the 'n' parameter. Prototype in pgmspace.h = extern int strncmp_P(const char *, PGM_P, size_t) __ATTR_PURE__; Or just use strcmp_P() Cheers, Paul

Intermittant UART Problems...
Shorting together wires in the RS232 connector is not a good idea. There should only be 2 that are ground, pin 5 which is signal ground and pin 1 which is protective earth/chassis...

Storing configuration data in the ROM
Hi, A tip you might not find in the EEPROM tutorial (if I weren't so lazy, I'd look but my internet connection seems dreadful slow for some reason). If you don't set the brownout...

My C deal with Microcarl
Hi John, Well the XML file just incremented vectors by 1, which being treated as 16-bit words was allowing 2 bytes per vector instead of 4. It's all O.K. now, but I still don't...
