how should i conect my avr dragon to my atxmega32a4u
You must keep Vcc within the datasheet range ! 4.2 V will get you into trouble with Xmegas ! How did you connect the PDI pins ?

Go to Studio's tool user guide in "Help" and find the AVR Dragon. Study that must connect PDI_Data and PDI_CLk, plus the Vcc and ground pins.

Simultaneous ADC sampling in XMEGA
You can read the first channel after the timer fires, with the other channels configured to convert immediately after that, 1 by 1. Then DMA the 4 channels when the 4th channel's...

XMega SPI Issues
Are you in the correct SPI mode and are you going by the memory's datasheet for reading / writing it ? Maybe you missed something there.

H/L register read/write order
No, order matters. Get and read the datasheet for the chip you have and find out what that is. :wink:

Need Opinion about My SPI code
It's not efficient to do multiple writes to SPCR in your spi_init(). Just use the names of which bits you want set, using the OR operator in a 1 line write and it's done. Also, to...
