* atsamd: Add Kconfig definitions for same51j19 and same54p20 chipsKevin O'Connor2022-10-131-1/+1
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* serial_irq: Support side channel for entering bootloaderKevin O'Connor2022-09-051-0/+2
| | | | | | Add a mechanism to request the bootloader when using serial input. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Use new CONFIG_USB to determine if USB needs to be configuredKevin O'Connor2022-08-161-2/+5
| | | | | | | | | | | | Introduce a CONFIG_USB build symbol that is set whenever CONFIG_USBSERIAL or CONFIG_USBCANBUS is set. Use that symbol during setup so that the USB controller is properly initialized for both usb serial and usb canbus bridge configurations. This fixes the clock configuration for usb canbus bridge mode on stm32f446. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* usb_canbus: Initial support for USB to CAN bridge modeKevin O'Connor2022-06-271-5/+7
| | | | | | | Support a USB interface that shows up as a canbus adapter to linux. Route both local and real canbus packets over that interface. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* canserial: Rename canbus.c to canserial.cKevin O'Connor2022-06-271-1/+4
| | | | | | | | | | Rename the canbus.c code to canserial.c and introduce new wrapper functions in canbus.c that connect the low-level canbus hardware code to the high-level canserial.c code. This is in preparation for adding "usb to canbus bridge mode". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Add support for disabling the canbus filterKevin O'Connor2022-06-271-0/+3
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Kconfig: Move SERIAL, USBSERIAL, and CANSERIAL definitions to src/KconfigKevin O'Connor2022-06-161-0/+6
| | | | | | There is no need to define these options in every board Kconfig file. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* canbus: Move canbus uuid calculation to canbus.cKevin O'Connor2022-06-161-6/+7
| | | | | | | | Move the uuid hash calculation to canbus.c and call canbus_set_uuid() from src/stm32/chipid.c . This simplifies the low-level canbus hardware code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Kconfig: Move CANBUS_FREQUENCY definition from src/stm32/Kconfig to src/KconfigKevin O'Connor2022-06-041-0/+5

* atsam: Add support for SAM E70Alex Maclean2022-03-261-1/+1
| | | | Signed-off-by: Alex Maclean <monkeh@monkeh.net>
* stepper: Add support for stepping on both edges of a step pulseKevin O'Connor2021-11-041-0/+3
| | | | | | | | | | Add an optimized step function for drivers that support stepping on both rising and falling edges of the step pin. Enable this optimization on 32bit ARM micro-controllers. Automatically detect this capability in the host code and enable on TMC drivers running in SPI/UART mode. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Make step pulse duration customizable at run-timeKevin O'Connor2021-11-041-25/+0
| | | | | | | | | | | | Remove the STEP_DELAY Kconfig option and replace it with a per-stepper step_pulse_duration printer.cfg config option. The AVR code will continue to have optimized code to step and "unstep" in the same function (which is automatically activated when the step delay is 40 ticks or less). This change removes the Kconfig option for single function step/unstep on 32bit processors. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* rp2040: Add initial support for the rp2040 mcuKevin O'Connor2021-07-041-0/+3
| | | | | | | Support the rp2040 (as tested on a Raspberry Pi Pico board). This adds basic uart, timer, gpio, and watchdog support. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Kconfig: Only show the "usb ids" menu if low-level options are enabledKevin O'Connor2020-05-311-7/+10
| | | | | | It's rare to customize the usb ids, so make it a "low-level" option. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Kconfig: Change the default usb vendor/product idKevin O'Connor2020-05-311-2/+2
| | | | | | | Change the product/vendor id to 0x1d50/0x614e, which has been reserved for Klipper (thanks to the openmoko project). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Kconfig: Add a new CONFIG_HAVE_STRICT_TIMING build definitionKevin O'Connor2020-05-311-0/+3
| | | | | | | | Add a new build definition to note micro-controllers that have strict timing. The Linux mcu code does not have strict timing - all other targets currently do. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: Rename stm32f4/ directory to stm32/Kevin O'Connor2019-08-051-6/+3
| | | | | | | Now that the code in stm32f4/ can handle both stm32f1 and stm32f4 chips, rename the directory to just "stm32". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* Kconfig: Move SERIAL_BAUD to src/Kconfig and show with LOW_LEVEL_OPTIONSKevin O'Connor2019-01-251-0/+8
| | | | | | | | Move the definition of SERIAL_BAUD to the main src/Kconfig file. Only show this as an option if the user selects the ability to configure low-level options. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* sam3: Merge sam4e8e support into sam3 codeKevin O'Connor2019-01-071-5/+2
| | | | | | | Most of the peripherals on the sam4e8e are similar to the ones on the sam3x8e mcu. Merge the code together and use just one code directory. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | Rename the HAVE_USER_INTERFACE definition in preparation for other "bit banging" interfaces. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sam4e8e: Add the SAM4e8e portFlorian Heilmann2018-08-081-0/+5
| | | | | | | | This can be flashed to e.g. the duet wifi using bossac. It requires a later version as is currently included in the klipper repo (1.8 vs. 1.2). Comms are currently via UART0 only, USB serial is still TBD Signed-off-by: Florian Heilmann <Florian.Heilmann@gmx.net>
* samd21: Initial support for SAMD21 micro-controllersKevin O'Connor2018-08-071-0/+3

* Add STM32F103 portGrigori Goronzy2018-04-091-0/+3
| | | | | | | | | | | | Add a fully functional STM32F1 port, currently mostly targeting STM32F103 microcontrollers. This requires an 8 MHz XTAL. The maximum possible step rate is around 282K steps per second. This uses stm32flash to burn the firmware. The bootloader needs to be started by setting BOOT0 to 1 and resetting the MCU. There is no automatic bootloader, unlike on Arduino. Signed-off-by: Grigori Goronzy <greg@kinoho.net>
* lcd_st7920: Add micro-controller code for the ST7920 LCD chipKevin O'Connor2018-03-061-0/+3
| | | | | | | Add support for passing messages to an ST7920 chip via a SPI bit-banging interface. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Initial support for running Klipper in a Linux real-time processKevin O'Connor2017-09-201-0/+3
| | | | | | | Add support for compiling the Klipper micro-controller code as a real-time process capable of running on standard Linux systems. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* build: Allow boards to disable digital input/output supportKevin O'Connor2017-07-201-0/+4
| | | | | | | | Allow the micro-controller code to be built without support for regular gpio pins. In this case, the code for endstops, steppers, and gpiocmds will be disabled. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* pru: Initial support for the Beaglebone PRUKevin O'Connor2017-05-151-0/+3

* sam3x8e: Add initial support for Arduino Due boardsKevin O'Connor2016-06-141-2/+4
| | | | | | | This adds basic support for running on the Atmel SAM3x8e micro-controllers that are found in the Arudino Due boards. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Support rescheduling of step events on faster MCUsKevin O'Connor2016-06-141-0/+7
| | | | | | | | | | On faster MCUs the step and unstep events may be too close for the stepper motor driver. Add a CONFIG_NO_UNSTEP_DELAY build option and support the case where it is not set. This allows faster MCUs to schedule two events for each step (one for the step and one for the unstep). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* pwmcmds: Add Kconfig option to allow boards to disable hardware PWM commandsKevin O'Connor2016-06-131-0/+3
| | | | | | | | 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>
* spicmds: Add Kconfig option to allow boards to disable SPI commandsKevin O'Connor2016-06-131-0/+3
