iom324pb.h, not in latest avr8-gnu-toolchain for linux
Hi,   That's avr-size (not avr-gcc) that doesn't know the device, but it doesn't really matter (IMO).   The crt... is "C Runtime" something. It's the interrupt vector...

iom324pb.h, not in latest avr8-gnu-toolchain for linux
And by "see it's content" you mean? $ ar t libatmega324pb.a eewr_block_xmega.o eerd_block.o eerd_byte.o eerd_dword.o eerd_word.o eeupd_block.o eeupd_byte.o eeupd_dword.o...

iom324pb.h, not in latest avr8-gnu-toolchain for linux
It's a zip-file, just use unzip. $ file Atmel.ATtiny_DFP.1.3.169.atpack Atmel.ATtiny_DFP.1.3.169.atpack: Zip archive data, at least v1.0 to extract $ $ unzip -l Atmel....

data is not being copied to DATA register of SPI interface in ATTINY 1616
Could that mean that the data has been transferred?   Yes it's (probably) transfered. But not received. The slave will only see at most a couple of zeros until it's...

XMEGA 128A1U USART BAUD RATE (4MHZ?)
Looks OK to me. But I don't use ASF/Start (or what you are using), only used XMega/USB with LUFA and it sets up 32MHz RC and DFLL for 48 MHz USB-clock. Like this /* Start the...

XMEGA 128A1U USART BAUD RATE (4MHZ?)
You can not use the 16MHz crystal as a common source to get both F_CPU=32Mz and F_USB=48MHz. One option is to use the crystal for F_CPU and let the internal 32MHz RC-oscilator be...

XMEGA 128A1U USART BAUD RATE (4MHZ?)
The default is to sample the RX signal 16 times on each bit, that gives a miximum of 3Mbit/sec with F_CPU=48MHz. If you use the double speed mode (CLK2X = 1) you can get up to...

XMEGA32e5 - timer ISR and volatile variable undeclared
The compiler can only "see" one .c file at a time so it doesn't know anything about the variable count when the ISR file is being compiled. Either put in a extern volatile...

ATTiny84 & SoftwareSerial
If you just add a one, you get two for free .   I mean, ATtiny841 is the successor of '84. It comes with two hardware USART's, a better RC oscillator and a lot of other...

trigonometric functions
I wouldn't do it myself, but you can call library functions from (gnu) assembler.   #include <avr/io.h> .data format: .string "sin(pi/4) = %f\n...

Program Execution Time: PROGMEM vs RAM
I think your crystal ball is very clear today, Theush.   uint8_t crc_dummy(uint8_t val) { uint8_t i; static const uint8_t crc_table[] = {0x00, 0xC1, 0x81, 0x40, 0x01...

Why not read the documentation you linked to?   unsigned char i2c_start ( unsigned char  addr )   Issues a start condition and sends address and transfer...
