* endstop: Rename mcu end_stop commands to endstopKevin O'Connor2019-07-121-35/+35
| | | | | | | | | Rename the commands. The main reason for this change is to force a micro-controller code updated (due to important bugfix in 7fefe52d). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Don't update SF_LAST_DIR if SF_NEED_RESETKevin O'Connor2019-07-121-1/+3
| | | | | | | | If the move is not added to the move queue, then the SF_LAST_DIR setting must not be changed. Otherwise, it could result in an incorrect direction being set on the stepper after a homing operation. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Reset LPC_UART0->FDR when using serialKevin O'Connor2019-07-101-0/+1
| | | | | | | | | | The popular "LPC17xx-DFU-Bootloader" alters the LPC_UART0->FDR register, so be sure to reset it back to its default when using serial in Klipper. Reported by @b-vs. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* lpc176x: Fix adc clock divisorKevin O'Connor2019-06-191-2/+2
| | | | | | | | Commit 1096075d changed CONFIG_CLOCK_FREQ to the actual cpu frequency, but that commit failed to update adc.c accordingly. That made the adc run 4 times slower. Make the corresponding change to adc.c. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* armcm_timer: Unify udelay() implementationKevin O'Connor2019-06-0910-42/+24

* 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>

* atsam: Improve i2c timeout detectionKevin O'Connor2019-05-231-15/+10

| | | | | | | Fixes GitHub Issue #1499. Resolves USB hang by forcing a minimum USB disconnection time at boot. Signed-off-by: Matt Baker <baker.matt.j@gmail.com>
* linux: add support for Linux hardware PWMJanne Grunau2019-04-056-4/+110
| | | | | | | | | | The replicape servo pins (P9_14/P9_16) are muxed to the SOCs hardware PWM unit driven by a 13MHz GP timer. They have to be driven by the linux host mcu. This commits adds hardware PWM support using the linux sysfs user space interface. Signed-off-by: Janne Grunau <janne-3d@jannau.net> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32f1: Fix ADC (#1474)smark-2019-03-311-1/+1
| | | | | The sampling time of the ADC was too slow (239 ADC clock cycles), causing the reading of the next ADC channel to have cross talk as per issue #1261. Sampling time updated to 41 ADC clock cycles. Signed-off-by: Marco D'Alessio <marco@wrecklab.com>

* pru: Avoid using a timer wake time of exactly zeroKevin O'Connor2019-03-311-0/+2
| | | | | | | | It appears the PRU timer will not trigger on a match of exactly zero. If the next timer happened to be set to exactly zero, it could cause software timers to get stuck and result in "move queue empty" errors. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Explicitly disconnect USB on a bootloader requestKevin O'Connor2019-03-311-1/+7
| | | | | | | | | It appears some host machines may not recognize that the USB device has disconnected upon start of bootloader mode. Explicitly disable USB and add a 5ms delay to help signal the host of the upcoming change. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stepper: Fix reset_step_clock corruption due to bitset typoKevin O'Connor2019-03-191-1/+1
| | | | | | | Commit b9b03dd0 had a typo in the flag updating. The typo could result in corruption of the stepper state. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* endstop: Use "pin_value" instead of "pin" when querying endstop stateKevin O'Connor2019-03-191-4/+4
| | | | | | | | | | Now that enumerations are available, any variable named "pin" can only be used to describe a gpio pin. Rename the end_stop_state "pin" parameter to "pin_value". Also, rename "end_stop_query" command to "end_stop_query_state" to notify users to upgrade both host and mcu code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
