What happened to __pgmx address space?
BTW, I’ve found a piossible bug in __memx implementation. Take a look at the following example: #include extern __memx const uint8_t _binary____intro8kHz8PWMHL_raw_end;...

What happened to __pgmx address space?
Ok, but __memx is a generic address space for SRAM and FLASH. How can I get a 24-bit pointer which points only into FLASH for devices with >64 kB of FLASH? And btw, can you take a...

__memx - initializer element is not computable at load time
It’s true. But when I specify __memx address space, the string will probably land in SRAM, not in FLASH memory? I can’t test it, because the code: #define PGM_STR(X) ((const...

Many TFT LCD controllers have 9-bit SPI mode. Very useful, because it don’t need RS control signal. It will be nice to have the SPI with possibility to send a preprogrammed...

XMEGA-AU four-port EBI
Atmel says that simulator is very similar to actual device, even bugs are simulated  I’m talking about Atmel Studio 6.x simulator, not AVR Studio. But we will see. What MCU...

XMEGA-AU four-port EBI
Please let me know if you will be able to run 4-port mode. It’s interesting why Atmel Studio simulator doesn’t support this mode. I don’t think that using reserved registers...

XMEGA-AU four-port EBI
How did you enable 4-port EBI configuration? In updated datasheet there is some information about it but it seems to be not correct. E.g. in Atmel Studio, when you choose...

Bug in gcc during access to GPIOR
Ok, I’ve just check 4.7.2 (Atmel Studio 6.1b toolchain) and indeed the bug disappeared and now everything works fine. Thanks.

Are XMEGA U shipped with preloaded bootloader?
Interesting information. As I said, yesterday I checked brand new XMEGA256A3BU, and it was shipped without bootloader (or it magically disappears). You say that XMEGA128A1U has...

Are XMEGA U shipped with preloaded bootloader?
Preloaded bootloader will not prevent you to use your own. So if you can, you can use preloaded bootloader, if not – you can use programmer to flash a new one. Pin assignment is...

Are XMEGA U shipped with preloaded bootloader?
Thanks. It is a wired strategy, competiting companies, ships their MCUs with preloaded bootloader, which greatly simplifies programming, but Atmel not. I can’t understand why,...
