| | | | | | | | library (#3165) Improved CAM bus ID generation, there were issues with ID collisions. Added a small fast hash library. Signed-off-by: Pontus Borg <liquidpontus@yahoo.se>
* linux: Set the SPI mode in spidev.cKevin O'Connor2020-07-311-0/+5
| | | | | | Fix omission causing the SPI mode to not be set on the linux mcu. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Disable hardware pwm when it is set to zeroKevin O'Connor2020-07-202-13/+12
| | | | | | | | | | | Only write "1" to the "enable" file when a non-zero pwm width is requested. Write "0" to the "enable" file when a zero pwm width is requested. This fixes a problem on the replicape servo lines that prevented them from being fully disabled. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Fix spi mode bitsKevin O'Connor2020-07-101-1/+1
| | | | | | | | The lpc176x hardware spi initialization code was swapping the CPOL and CPHA bits. This caused the MAX31865 and MAX31856 chips to not work correctly. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Improved CAN support for STM32 (#2976)bondus2020-06-247-279/+493
| | | | | | | | | Reworked the STM32F0 CAN bus implementation. It's more robust and higher performance. Added support for function remapping to different pins. API is emulating an STM32F0. Improved and ported CAN bus to STM32F0, F1 and F4. Signed-off-by: Pontus Borg <glpontus@gmail.com>

* 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>
* lcd_hd44780: Only calibrate cmd_wait_ticks on mcus with strict timingKevin O'Connor2020-05-311-0/+5
| | | | | | | The calibration isn't valid on the linux mcu, so make it dependent on CONFIG_HAVE_STRICT_TIMING. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lcd_st7920: Only calibrate wait ticks on mcus with strict timingKevin O'Connor2020-05-311-0/+6
| | | | | | | The calibration isn't valid on the linux mcu, so make it dependent on CONFIG_HAVE_STRICT_TIMING. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Make toggling the step gpio after timer read conditionalKevin O'Connor2020-05-311-1/+5
| | | | | | | On the Linux mcu, toggling the pin after the time is read is not valid. Make that optimization dependent on CONFIG_HAVE_STRICT_TIMING. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* Kconfig: Add a new CONFIG_HAVE_STRICT_TIMING build definitionKevin O'Connor2020-05-317-0/+9

* linux: Adapt servo0 channels for beagleboard kernel 4.14.108-ti (#2746)Janne Grunau2020-05-031-12/+29
| | | | | | | | | | | | | | The beagleboard TI kernel 4.14 and 4.19 contain a commit which change the device names ("pwm: Create device class for pwm channels") from pwmN to pwm-${chip}:N. This commit was never merged into the upstream kernel. Decrease the number of pwm channels to a more reasonable 16. Increase the number of pwm chips to 8 since the replicape servo pwm outputs are on pwmchip4. Update replicape code to detect appropriate channel. Signed-off-by: Janne Grunau <janne-gh@jannau.net>

* stm32: Explicitly reset peripheral clocks on stm32f1Kevin O'Connor2020-03-241-0/+5
| | | | | | It appears some bootloaders do not properly reset some peripherals. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* armcm_boot: Additional code for broken bootloadersclearchris2020-03-041-0/+9
| | | | | | | | Explicitly disable the SysTick interrupt and explicitly set the stack pointer, as some bootloaders aren't handling this correctly. Signed-off-by: Chris Lombardi <clearchris@hotmail.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: Revert "stm32: performance improvement for spi on stm32f0"Kevin O'Connor2020-03-041-8/+4
| | | | | | | | | | | This reverts commit a2c309a2b02d16ec15fee5702463621239261266. The above commit is causing crashes on the stm32f103xb chip when spi is in use. It's unclear what the cause of the regression is, but the optimization isn't required so revert it until the root cause can be determined. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: add alternate pinouts for spi1/2Arne Jansen2020-01-231-3/+9
| | | | | | | In addition to spi3, spi1 and spi2 also have alternate pins. Add them as spi1a and spi2a, similar to spi3. Signed-off-by: Arne Jansen <arne@die-jansens.de>
* stm32: performance improvement for spi on stm32f0Arne Jansen2020-01-231-4/+8
| | | | | | | | | | The stm32 has a small queue for spi tx/rx. The current code only uses the spi with a single byte buffer, effectively waiting for each byte to complete before starting the next transfer. This patch changes the structure of spi_transfer() to make use of the queue and achieve back-to-back transfer of bytes on spi. Signed-off-by: Arne Jansen <arne@die-jansens.de>
