* gpiocmds: Merge digital output and soft pwm codeKevin O'Connor2020-12-101-233/+119
| | | | | | | | The digital output commands implement a subset of the software pwm commands. Change the host code to just use the software pwm commands and simplify the micro-controller code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Use move queue for software pwmKevin O'Connor2020-12-041-41/+78
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Use move queue for digital output pinsPascal Pieper2020-12-041-11/+57
| | | | | Signed-off-by: Pascal Pieper <accounts@pascalpieper.de> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Send soft pwm cycle_time separately from schedule_soft_pwm_outKevin O'Connor2020-12-041-11/+22
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Add soft-pwm frequency modulation supportGuy Shapira2020-09-261-10/+9
| | | | | Signed-off-by: Guy Shapira <gayuha@gmail.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Specify soft pwm duration in clock ticksKevin O'Connor2019-05-261-12/+6
| | | | | | | | Improve the precision of soft pwm pulses by allowing the host to directly specify the clock duration of the pulse. This improvement in precision may be noticeable when controller servos (and bltouch). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* command: Always pass a string to the DECL_CONSTANT() macroKevin O'Connor2019-03-171-1/+1
| | | | | | | | Make it clear that the name of the constant being defined is a string. When the value being defined is also a string, use a new DECL_CONSTANT_STR() macro. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Add update_digital_out commandKevin O'Connor2018-06-271-0/+15
| | | | | | | Add a command that can immediately set the value of a digital output pin created with config_digital_out. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Introduce and use gpio_out_toggle_noirq()Kevin O'Connor2018-05-151-1/+1
| | | | | | | | | | | | | | | The gpio_out_toggle() function in the sam3x8e and stm32f1 code was only valid if it was called with irqs disabled. Commits 018c5daa and 9c52ad43 enabled the lcd code which called gpio_out_toggle() with irqs enabled. This could cause corruption of the gpio state. Introduce a gpio_out_toggle_noirq() function that will only be invoked with irqs disabled, and fix gpio_out_toggle() on sam3x8e and stm32f1 so that it safe to call even if irqs are enabled.

* gpiocmds: Clear SPF_NEXT_* flags on new schedule_soft_pwm_outKevin O'Connor2017-12-161-2/+2
| | | | | | | Properly handle the (unlikely) case that a schedule_soft_pwm_out command is received before a previous command is fully processed, Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Allow the start value for a pin to differ from the default_valueKevin O'Connor2017-10-121-9/+11
| | | | | | | | | Allow the start value to be different from the default/shutdown value for the pin. This will be useful for "heater fans" that should startup in the off state, and transition to full on in a shutdown state. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* build: Use compile_time_request system for init, tasks, and shutdownKevin O'Connor2017-05-261-2/+2
| | | | | | | | Avoid using linker magic to define the init, task, and shutdown functions. Instead, use the compile_time_request system. This simplifies the build and produces more efficient code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Change MAX_SOFT_PWM from 255 to 256Kevin O'Connor2017-05-151-6/+5
| | | | | | | Change the range of values used for software PWM to avoid doing an integer division in the main code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* pwmcmds: Export the maximum PWM valueKevin O'Connor2017-05-151-3/+6
| | | | | | | Instead of assuming the maximum PWM value is 255, export a constant from the firmware to the host with the maximum value. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* timer: Allow board code to define its own timer_is_before implementationKevin O'Connor2017-03-261-3/+4
| | | | | | | | | | | | Move sched_is_before() from sched.c to timer_is_before() in the board specific timer code. This allows the board code to provide its own definition. Also, remove the sched_from_us() and sched_read_time() wrapper functions and change the callers to directly invoke timer_from_us() / timer_read_time(). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Rename sched_timer() to sched_add_timer()Kevin O'Connor2017-03-111-3/+3
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* basecmd: Use oid_ prefix for the oid manipulation functionsKevin O'Connor2017-03-091-5/+5
| | | | | | | Consistently use an "oid_" prefix on the oid functions - this makes them similar to other functions with a common prefix. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Use uint_fast8_t for return type of timersKevin O'Connor2016-06-141-5/+5
| | | | | | | | Some architectures are faster passing regular integers than 8bit integers. Use uint_fast8_t so that the architecture chooses the appropriate type. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* irq: Prefer irq_disable/enable instead of irq_save/restore in cmds/tasksKevin O'Connor2016-06-131-3/+3
| | | | | | | | Task and command handlers always run with irqs enabled, so it is not necessary to save/restore the irq state when disabling irqs in these handlers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* pwmcmds: Add Kconfig option to allow boards to disable hardware PWM commandsKevin O'Connor2016-06-131-70/+2
| | | | | | | | Some boards may not support hardware based PWM. Update the build so that those commands do not need to be compiled if they are not available. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* gpiocmds: Add Kconfig option to allow boards to disable ADC commandsKevin O'Connor2016-06-131-111/+0
| | | | | | | | Some boards may not support the ADC hardware. Update the build so that those commands do not need to be compiled if they are not available. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
