* atsam: Configure the atsam sram matrix registerKevin O'Connor2019-02-071-0/+11
| | | | | | | | The sram matrix configuration is, bizarrely, configured with a slow default. It will typically add an extra wait state to every memory access. Set the matrix sram controller to improve the performance. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* armcm_timer: Add a generic timer mechanism for ARM CortexM3/M4 chipsKevin O'Connor2019-02-061-0/+136
| | | | | | | | | | | | The ARM CortexM3 (and later) chips almost always have a 32bit timer in the "Debug and Watch Trace" (DWT) unit which resides within the cpu core itself. This timer is generally faster to access than timers located on the chip's peripheral bus. When combined with the standard ARM SysTick timer it provides a (generally) portable mechanism to implement Klipper's software timer mechanism. It's generally also faster than using the vendor specific timers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* adccmds: Run gpio_adc_setup() before oid_alloc()Kevin O'Connor2019-01-131-1/+2
| | | | | | | | Order the adc config code so that a shutdown from gpio_adc_setup() doesn't result in analog_in_shutdown() running on a 'struct analog_in' that hasn't yet been configured. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stepper: Fix bug when using a non-zero CONFIG_STEP_DELAY on AVRKevin O'Connor2019-01-111-1/+1
| | | | | | | | Make sure to explicitly cast to 32bit integers when doing math on 16bit integers that require the extra precision as the AVR uses a 16bit int. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Support configuring the stepper pulse length from KconfigKevin O'Connor2019-01-093-15/+41
| | | | | | | Allow the stepper pulse length to be configured at compile time from the Kconfig menu system. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* i2ccmds: Pass the i2c address as a 7-bit number (0-127)Kevin O'Connor2019-01-074-7/+5
| | | | | | | | | | | | | | | | The sam3 i2c code and the linux code use a 7-bit i2c address, while the avr, lpc176x, and samd21 i2c code uses an 8-bit address with the least significant bit always zero. A similar issue occurred in the host code (sx1509.py and replicape.py use 7-bit addresses while uc1701.py and mcp4451.py use 8-bit addresses). Consistently use 7-bit addresses in all the code. This breaks compatibility between host and mcu software, so make a change to the config_i2c command to force users to synchronize software updates. This also breaks common Smoothieboard configs, so update the mcp4451 code to validate the i2c_address. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
