Baud vs bits/sec?
Steve, I don't think your explanation is correct. I believe Clancy's description of baud is accurate. As Clancy states, baud is the symbol changes per second. It has nothing to...

Charge Pump
To me, it seems it would be easier to just put the LED's in parallel instead of in series. I have controlled 30 LED's from one port before by just putting them all in parallel....

Mega16 -> Mega128 Parallel Connection Voltage Drop
PD1 on the ATmega128 is also used for the TWI. Are you sure you have not enabled the TWI?

Baud vs bits/sec?
The way I understand it, for a simple UART, baud rate and bit rate are equivalent. Baud rate is symbols per second. For a UART, there are two symbols, high or low, which each...

AVR - can it be programmed to output clocks for CD AUDIO
Of course, if you used a timer interrupt firing every 8 cycles, there would be no cycles left to do anything else. Even sp1nm0nkey's example as is would probably take more than 8...

how do you pull the chip off a STK500?
Personally, I have found when using those simple tweezer like IC pullers, I am MORE likely to bend the pins significantly. I prefer the small screwdriver approach alternating...

AVR - can it be programmed to output clocks for CD AUDIO
You could use the PWMs of an AVR to generate the divided clocks.

Inlined Delay Algorithm
Cool... I noticed the _NOP2 function is implemented as "rjmp 1". I will have to remember that the next time I need two NOPs. The lpm for _NOP3 is also an interesting idea....

MEGA168 signature 0xFF,0xFF,0xFF after debugwire session
The errata in the ATmega8 datasheet has the following on page 296: Quote:3. Signature may be Erased in Serial Programming Mode If the signature bytes are read before a chiperase...

MEGA168 signature 0xFF,0xFF,0xFF after debugwire session
I have seen something similar happen on an ATmega48, except it was not after a debug wire session but after reprogramming via ISP mode. Similar to what you are seeing, the...
