Ralf Schlatterbeck fbe6ae6a60 Fix off-by-one error in digitalPinToTimer 2014-11-19 13:53:53 +01:00
Ralf Schlatterbeck ddbfd6712c Remove obsolet macro in example 2014-11-19 13:53:44 +01:00
Ralf Schlatterbeck abdf6f8c6b Refactor A/D conversion in adc.c
Now the necessary settings are in adc.h. Refactored to allow repeated
ADC reads without reinitialization. Arduino allows setting
analogReference, this is now also implemented.
ADC is now initialized to sane values in apps/arduino/arduino-process.c
dev/arduino/arduino-compat.h now has all hardware independent settings
for arduino (some moved from platform/osd-merkur/dev/hw-arduino.h).
turnOffPWM re-implemented with hw_timer, removed from wiring_digital.c
ADC-specific arduino stuff moved to arduino-compat.h
Arduinos wiring_analog no longer necessary.
arduino-sketch example now reads analog inputs 1 and 5 using analogRead.

Ralf Schlatterbeck d5284eebe1 Factor resources, fix time
Now there is a generic resource that can generate and parse
application/json as well as text/plain. It can be re-used, only the
from_string and to_string routines have to be written and the resource
properly set up. A new resource format is specified, see
GENERIC_RESOURCE in, e.g., examples/osd/pwm-example. This is now used in
all my examples, namely pwm-example, arduino-sketch, wallclock-time.

There was an off by one error for the month in time formatting (in
gmtime and localtime). And the leap-year computation was broken. Both
fixed now, so we get a correct date. For localtime we are still 2 hours
off because daylight saving isn't implemented yet.

Also renamed gmtime to utc.

Ralf Schlatterbeck fd54bc9ca4 Inline timer init functions, no static storage
Hardware init function profit a great deal from being inlined if the
given parameters are constant -- which is the common use-case, we could
probably call this for all timers and still have less overhead. The
hwtimer_pwm_ini (which calls hwtimer_ini) gets completely computed at
compile-time resulting only in the register settings of hwtimer_ini.

This is now possible because we get rid of static storage for the
max_ticks and instead compute this in hwtimer_pwm_max_ticks from the
timer register settings.

Ralf Schlatterbeck c46d6afa39 Make Arduino timer stuff work on Contiki
New discovery: Contiki also uses timer 0. With almost the same interface
as Arduino. So we now completely get rid of wiring.c (only the main
file, the other wiring_xxx stay) and implement Arduino timer, delay, etc
in terms of the corresponding Contiki routines. Verified that now delay
works as expected. The LED in examples/osd/arduino-sketch blinks!

Before this, the arduino_init routine in wiring.c destroyed the timer-0
initialization of contiki, making both, contiki timer implementation
*and* contiki timer implementation fail if the arduino_init routine was
called. Now both work.

Squashed with following bug-fix commit.

Ralf Schlatterbeck 08abd8807d Fixes for platform timer code
Some platforms are missing timer channels, this is now left to the
(missing) preprocessor definitions on those platforms, no
platform-specific defines needed anymore.
Also fix usage of timer counter register 3 (hardcoded) in
cpu/avr/dev/clock.c -- this code isn't used on many platforms as it
requires a very special quartz clock frequency but this now also uses
the platform timer specification.

Ralf Schlatterbeck b6be226e69 Add Arduino compatibility layer
We can now directly compile arduino sketches (.pde) files.
Arduino compatible analogWrite works now.
But there is still a long way to go, serial I/O and timer stuff (delay,
millis etc) currently don't work (not tested but I don't expect this to
work).
It can be used in an arduino sketch or in a normal contiki program.
We get a PWM frequency of 490.2 Hz (a period of 2.040 ms), that's
Arduino compatible. If you need different frequencies see native timer
usage in examples/osd/pwm-example
In a contiki program you have to call arduino_pwm_timer_init to
initialize the timer before pwm works. The arduino sketch wrapper
already does this.
For running a sketch, see examples/osd/arduino-sketch

Ralf Schlatterbeck cfec3c6e2d Initial implementation of avr hardware timer
Mainly for PWM use for now.
With example to set the LED to different brightness via COAP.
We switch the LED with 50 kHz (20µs) in this example.

Ralf Schlatterbeck b4fb8c3f52 Add wallclock time handling
New application and new example.
We use the built-in timer routines and add an offset to get the
wallclock time. The offset can be set by time-changing routines
(currently only settimeofday).
We also maintain an offset for timezone handling but this isn't
currently fully implemented.

Ralf Schlatterbeck 56f6f87c94 Allow changing bootloader_get_mac address
Current default in the Makefile is the *new* bootloader address.
But for backward compatibility we've modified the run*.sh files
to use the old address. The run*.sh also now explain how to change
the default.
