Issue
QMatrix Touch Sensing on XMEGA AVRs
The Pins PE6,PE7 and PF5 of
ATxmega<xxx>A3 devices do not work for
touch sensing when tested along with STK600
GCC compiler Optimization issue with
QMatrix Libraries on ATtiny167
In case of QMatrix GCC library for ATtiny167,
few channels produces low signal and reference
value compared to other channels, when tested
with STK600.
GCC Compiler Issue for ATmega128RFA1
device
The Latest GCC WinAVR-20090313 is having
problems with ATmega128RFA1 device. It
places the .data section to the memory location
0x800100 instead of 0x800200.

Rule Description
Rule states that all code
shall conform to ISO 9899
standard C, with no
extensions permitted.
Rule states that Illegal
implicit conversion from
Underlying long to unsigned
long
This Rule says that a 'U'
suffix shall be applied to all
constants of 'unsigned' type
Rule states that In the
definition of a function-like
macro, each instance of a
parameter shall be enclosed
in parenthesis
Rule states that there shall
be at most one occurrence
of the # or ## preprocessor
operator in a single macro
definition
Cause
Exceptions Reason
This Rule is not supported as the library
implementation requires IAR extensions like
__interrupt. These intrinsic functions relates to
device hardware functionality, and cannot
practically be avoided
The library uses macros to combine symbol
definitions to form a unique expanded symbol
name and in this, the usage of unsigned qualifiers
for numeric constants (e.g. 98u) causes name
mangling. This is the only occurrence of this error
in the library.

definitions to form a unique expanded symbol
name and in this, the usage of unsigned qualifiers
for numeric constants (e.g. 98u) causes name
mangling. This is the only occurrence of this error
in the library.
There is one instance where the library breaks this
rule where two macro definitions are combined to
form a different symbol name. Usage of
parenthesis cannot be used in this scenario.
There is one instance in the library where this rule
is violated where the library concatenates two
macro definitions to arrive at a different definition.
Remedy / workaround
Suggested to use combinations with
other ports
Suggested to use the default
Optimization level of –O0 for
ATtiny167 in case of GCC.
In the linker options for the GCC
project of ATmega128RFA1 device ,
the following options have to be
added:
-Wl,--section-
start=.data=0x800200
