| | | | Signed-off-by: Matt Baker <baker.matt.j@gmail.com>
* lpc176x: force minimum usb disconnect timeMatt Baker2019-04-063-0/+19
| | | | | | | 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>
