passing a pointer to ROM in a function
I've read about the PGM stuff and that is working. But I also see the following in Studio 6: "The AVR is a Harvard architecture CPU. This means that it separates instruction...

correct setup for 153.6KHZ crystal on an ATMega328
Anybody any idea about how to get the ATMega328 running at a 153.6kHz crystal? I've had it running once with 2 100pF capacitors and selecting full swing oscillator. With "low...

Studio 6 with ATMega328 @ 156kHz
Anyone got experience with debugging at low frequencies of an ATMega? I can't get it working at all. I can set the fuses, go to debugging and it automatically enables DW. Then I...

write of high byte of OCR1A/OCR1B in ATMega328 is wrong
I'm out of options I'm afraid :(. I can't get a decent value (in C code) into the 16 bit OCR1 register(s) of an ATMega328. I've tried 16 bit access, high byte then low byte and...

timer CTC mode and NOT using output pin
In other words: is it possible to use the timers in CTC mode only internally? The output pins have to be used as general digital IO. I need a timer generating interrupts at a...

string constants
I've started to convert our project files from Zilog to Atmel (Xmega part). Our code is minimalistic as possible. If we can avoid using a function, we will do that. Now I'm having...
