misc: Update NO_COLOR define switch
The NO_COLOR define switch is a preparation for the Windows version.
Since the standard Windows command prompt is not able to display
ANSI color statements correctly. With this define switch it is
possible to remove any coloring of the output. This will be set
automatically in the MinGW patch.
The color definitions are moved from sim_core.c to sim_core.h since
they are used in other macros as well.

Makefiles: Add manual and a global doc target
Manual generation is now included in the doc/Makefile. Additionally,
a doc target has been added to the global Makefile.
doc: Add simavr manual
This is an excerpt of the bachelor's thesis "qsimavr: Graphical
Simulation of an AVR Processor and Periphery" by Jakob Gruber. The full
thesis is available at https://github.com/schuay/bachelors_thesis.
misc: Point to correct simavr include dirs
misc: Move avr_mcu_section.h to sim/avr
Since sim_elf.h includes avr_mcu_section.h, it needs to reference
a path which works both during simavr builds, and compilation of
external programs including sim_elf.h. Adding the avr/ subdirectory
to pkg-config cflags is not desired, to make sure it's clear that header
is shared between the sim and the firmware.
Makefiles: Remove executable bit from headers
Makefiles: Separate simavr.pc and simavr-avr.pc
According to http://people.freedesktop.org/~dbn/pkg-config-guide.html,
"each pkg-config file is best used to describe a single library, so each
package should have at least as many pkg-config files as they do
installed libraries."
Makefiles: Use PREFIX instead of DESTDIR in simavr.pc
This is needed when DESTDIR does not equal the actual intended
destination (this usually occurs when building packages for
distribution).
An example make invocation:
make DESTDIR=pkg/usr PREFIX=/usr install
core: Deinitialize GDB in avr_terminate()
This is relevant when running multiple simavr sessions in a single
program.
cores: Use correct extint control register
The atmega1280/atmega1281/atmega128/90usb162
have two external interrupt control registers;
EICRA for ISC[0-3]x, and EICRB for ISC[4-7]x.
vcd: Made the trace buffer dynamic

ioport: Restore PIN to PORT values when DDR is set to output
ioport: Use IRQ_FLAG_FILTERED instead of manual filtering
Manual filtering could cause us to miss pin changes when data
is written to PINs while the port is set to input mode (and thus
the PORT register is not updated).
vcd_file: Update comment to reflect correct time units
timer: Avoid infinite cycle timer on TCNT write
In some situations, it was possible to enter an infinite cycle timer
loop. In avr_timer_tcnt_write, the tov cycle timer registration is not
protected and can register a timer with p->tov_cycles == 0.
The following atmega1280 program demonstrates this issue:
int main() {
TCCR1A = 0;
TCCR1B = (1<<WGM12) | (1<<ICES1);
OCR1B = OCR1A = 960;
/* Start */
TCNT1 = 0;
TCCR1B |= (1<<CS11);
/* Stop */
TCCR1B &= ~(1<<CS11);
TIFR1 |= (1<<OCF1A) | (1<<OCF1B);
/* Start */
TCNT1 = 0; /**< Registers timer with tov_cycles == 0. */
TCCR1B |= (1<<CS11);
while (1) ;
return 0;

timer: Convert to logging to AVR_LOG()
core: Introduce a logging macro AVR_LOG()
This works in conjunction with avr->log to tune out messages we are not
interested in. LOG_ERROR is the default level.
run_avr: Add -v argument to raise verbosity level
Pass it more than once to raise it further. This works better with the
standard conventions, which would allow passing -vvv (instead of -v -v
-v). Unfortunately, this does not work here.
The type of avr->log has been altered to accomodate values up to 3.
cores: Move static to front of declaration
This fixes the two -Wold-style-declaration warnings reported by gcc with
-Wextra.
mega1280: Initialize UART 2 and 3
These definitions already existed but were not initialized.
mega1280: Add missing timers 4 and 5
These are 16-bit timers similar to Timer1 and Timer3.
core: Increase MAX_IOs for atmega1280
The atmega1280 uses IO registers up to an address of 0x136.
Set MAX_IOs to (0x136 - 0x20 + 0x01) = 279.
core: Don't sleep with pending interrupts
This avoids an issue in which we would incorrectly enter a state in
which the CPU was sleeping and interrupts were disabled. It occurred
when an interrupt was raised and a SLEEP instruction processed before
the interrupt could be serviced (due to pending wait).
There are several disadvantages: if somebody adds new code which
switches the CPU to sleeping, there's a good chance of them forgetting
to add this check. Preventing sleep even if the interrupt is masked is
probably harmless but incorrect. Finally, on a real AVR it _is_ possible
to trigger an interrupt and then go to sleep in the next instruction
before the interrupt is serviced.
I'd actually prefer fixing this by moving the CPU interrupt wakeup from
avr_raise_interrupt() to avr_service_interrupts(), but that requires
further changes to avoid sleeping during avr->run() while an interrupt
is about to be serviced.
cores: Set raise_sticky in TWI interrupt vectors
interrupts: Introduce raise_sticky flag
If set, the raise bit is not cleared in avr_clear_interrupt. This
corresponds to the hardware not clearing the interrupt flag when
executing the interrupt routine.
The only known example of this is the TWI Interrupt Flag TWINT.
interrupts: Do not clear raised bit twice
avr_regbit_clear is already called in avr_clear_interrupt.
twi: Correct swapped twi irq names
interrupts: Typo correction (pooling -> polling)
misc: Consistent include guards in headers
Changed all include guard defines to a consistent form and added them if
missing.
misc: Add extern "C" blocks to headers
Most headers already had these. This commit adds them where they weren't
included yet.
simavr: Do not call avr_terminate in run callbacks
Neither run_avr nor the examples expect avr_terminate to be called by
simavr itself.
This also caused issues for cleanup code (such as IRQ disconnections)
that did not know if avr_terminate had already been called or not.
irq: Print errors to stderr
Trying to (dis)connect an invalid IRQ is an error. Note that the
incorrect function name printed in avr_unconnect_irq has been corrected.
twi: Move avr_twi_irq_msg to avr_twi.c
This fixes inclusion of avr_twi.h into C++ files.
interrupts: Don't wake up if not sleeping
This caused the CPU to wake up even if it was explicitly set to
cpu_Stopped.
Makefile: Create .deb files using fpm
Handy way of creating debian packages quickly
Signed-off-by: Michel Pollet <buserror@gmail.com>
examples: Correct instructions for timer_64led example
run_avr: Abort if firmware could not be read
Otherwise, simavr continues and tries to process whichever random memory
content is located in the flash memory section even when the file could
not be read.
examples: hd44780 responds on falling edge of E pin
The example itself works both ways, but the actual HD44780 chip
processes data on the falling edge - see the data sheet.
examples: Fix frequency of ac_input signal
The comment in ac_input.h specifies 50 Hz, but it was actually 500 Hz.
This off-by-one-zero error probably went unnoticed because of inaccurate
sleep handling (which was fixed in the previous commit).
simavr: Improved accuracy of sleep durations
This commit solves (or at least improves) an issue that occurs when
short sleep times are requested in avr_callback_sleep_*. The operating
system cannot accurately handle short sleep requests, and sending many
short requests takes significantly longer than requesting the equivalent
time in longer bursts. This can be observed by running the board_hd77480
example - the counter is much slower when vcd recording is turned on
(= short sleep requests) than when it is turned off (= long sleep
requests).
We improve this situation by accumulating sleep requests until a certain
minimum count of pending usecs is reached which can be handled somewhat
accurately (200 microseconds worked well for me).
gdb: Read/write SREG values correctly
Accessing SREG through gdb seems to have been broken since SREG is no
longer synthesized at each instruction (
2f67001d). As a quick fix, make
SREG accessors public and use them in sim_gdb.
Note that invalid avr->sreg values no longer trigger the CRASH macro.
tests: Correct expected output of atmega88_uart_echo
Carriage return generation was added back to the file handler in
a26a2e43fc4b547090f3069e121713702593261d. Since the string is actually
passed through uart_putchar twice, the received string has a duplicate
'\r' character.

misc: Fix confusing typo in error message
gdb: Use early termination in gdb_watch_find*
gdb: Implemented watchpoint handling
Per data access, we never signal more than one watchpoint. Possible
scenarios are several watchpoints at the same address (for example
WATCH_ACCESS and WATCH_WRITE) or overlapping watchpoint ranges. This is
not completely correct.
gdb: Store watchpoints in avr_gdb_t
For now, quietly assume that all watchpoints are located in SRAM (with
0x800000 offset).
gdb: Prepare watchpoints_t data structure
In preparation for the watchpoint implementation define an
avr_gdb_watchpoints_t struct to handle both. The struct is only accessed
through gdb_watch_* functions, therefore changing its internals should
be easy.
Note that this implementation cannot handle different watchpoints at the
same address with a different size.
The avr_gdb_watch_type enum is public and will be used in sim_core.c in
a follow-up commit.
