* flash_usb: use sudo for rp2040 flashingLasse Dalegaard2022-01-311-1/+1
| | | | | | | | | | | The rp2040 can be flashed without sudo when using udev rules to give the user permission, but in a standard configuration sudo is required. Here we make it possible for flash_usb to use sudo for the rp2040 target, and make it the default when using `make flash` for the rp2040. As for other targets, one can set `NOSUDO=1` to not call through sudo. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>

* rp2040: implement I2CLasse Dalegaard2022-01-124-0/+227
| | | | | | | This implements I2C for the rp2040 target. All output groupings of both I2C blocks are available for use. Signed-off-by: Lasse Dalegaard <dalegaard@gmail.com>

* rp2040: add make flash supportLasse Dalegaard2022-01-061-6/+7
| | | | | | | | | | | | | | | | This adds `make flash` support for the rp2040 target. Flashing is performed using a custom `rp2040_flash` tool that uses the PICOBOOT protocol. Root is not required. The user specifies the serial device of the rp2040 they wish to flash as the device. This device is reset into bootsel mode and `rp2040_flash` is invoked on the original USB device path. If the device is already in bootloader mode, the user can specify 'first' as `FLASH_DEVICE` which will simply invoke `rp2040_flash` with no bus/address options.

* stm32: Unify enable_pclock() codeKevin O'Connor2021-12-308-238/+125
| | | | | | | | | Unify the handling of the enable_pclock() and is_enabled_pclock() code across all stm32 chips. All chips will now perform a peripheral reset on enable_pclock() (this is a change for stm32f0 and stm32h7). The enable_pclock() code will now also disable irqs during the enable.

* stm32: Rework register access on stm32f0_adc.cKevin O'Connor2021-12-231-34/+25
| | | | | | | | | | | Avoid read-modify-write operations where possible. The register values are in a known state so prefer absolute writes. Improve handling of race conditions with hardware updates. Remove the adc reference from "struct gpio_adc" as it is a constant. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stepper: Add support for stepping on both edges of a step pulseKevin O'Connor2021-11-047-7/+50
| | | | | | | | | | 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.

* stepper: Make step pulse duration customizable at run-timeKevin O'Connor2021-11-043-91/+47
| | | | | | | | | | | | 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>
