Pointer arithmetic fails
Ignoring the utter uselessness of this program, follow the logic with me: I have SomeData in memory, and set the bytes to some meaningless values. I have also built a struct and...

Simulating eeprom_update_block
In an xMega part and Studio 6.1 eeprom_update_block((uint8_t *) p-0x1000, &j, siz+4); I have NVM_CTRLB |= (1<<3) ; so I can read the eeprom data like anything else. I'...

data definition has no type or storage class
RemPut(uint8_t dt, uint16_t i, uint8_t * value, uint8_t siz) ; I have this line of code in a .h file. The compiler points to it and complains. I don't know enough to...

The insidious RTC
I've been using one of the counters to count time, but it seems silly to use one of these just to generate interrupts when it could be doing something more useful and there's that...

TIP! The code that makes the useless pdf less useless.
When you're looking for how to do something, and google sends you to an atmel PDF, you'll find a few brief paragraphs. Then it says, "The source package consists of..." So, where'...

Minor AS6.1 bug
I made a small test program for an xMega8E5. Naturally, it didn't work. Since you can't simulate an xMega8E5, I changed the processor to an xMega192D3. Changing the processor...

Why etch your own board?
Frustration --> Concept --> Working device in one day. It's an xMega8E5, a moosey (or is that mousey) H bridge and space for an NRF24L01 module. Intended for a couple amps. I...

Your interrupt not interrupting?
If your interrupts refuse to interrupt and you're starting to pull hair, or search the freaks, remember, in the xMega, you have to set the PMIC.CTRL register :wink:

Read the EEProm
"All XMEGA devices have EEPROM for nonvolatile data storage. It is addressable in a separate data space (default) or memory mapped and accessed in normal data space... ...Memory...

Measuring the battery current.
Looking for like 6 amp max in a battery system between like 10 and 30 volts, I'd like to measure the battery current. This idea puts a .01 ohm shunt in the - supply lead. Needs an...
