* altos/lpc: Add fast timerKeith Packard2016-03-26
| | | | | | This offers a faster timer callback for higher-precision operation Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Missing */ in definition of PIO0_4Keith Packard2013-12-20
| | | | | | Would maek using these values pretty hard. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Add boot loaderKeith Packard2013-06-24
| | | | | | Support the USB boot loader, add USB pull-up support. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Don't disable all interrupts when disabling one interruptKeith Packard2013-06-22
| | | | | | | | | The nvic iser and icer registers read value indicates all enabled interrupts, icer writes disable the set interrupts. Re-writing icer with the current value ends up disabling all interrupts, not exactly what we wanted. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Enable brown-out-detectorKeith Packard2013-06-22
| | | | | | Make sure the processor does something sensible when the power disappears. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Filter ADC inputsKeith Packard2013-06-15
| | | | | | | They're amazingly noisy on EasyMini, so just filter them as the only thing we use them for is battery and pyro numbers. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Allow for alternate SPI SCLK0 pin usageKeith Packard2013-05-19
| | | | | | | SPI SCLK0 can appear on three different pins; let the application configure which one it wants. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Fix beeper driverKeith Packard2013-05-19
| | | | | | | | Set prescale limit, not current prescale value (pr instead of pc). Flip output 1 on PWM match (set emc toggle for channel 1). Don't hold counter in reset (turn off CRST bit). Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: add gpio int, spi, adc and ct32b defines to lpc.hKeith Packard2013-05-18
| | | | | | Lots more devices Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Clean up broken IOCONF definesKeith Packard2013-05-18
| | | | | | Missing comment closes Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Get USB workingKeith Packard2013-05-17
| | | | | | | The lpc demo now has a USB command line. Also allocates system stack so we know when ram is tight at build time Signed-off-by: Keith Packard <keithp@keithp.com>
* altos: Finish off LPC USB register definitionsKeith Packard2013-05-17

* altos/lpc: Start adding USB register definitionsKeith Packard2013-05-17
| | | | | | Just the bare struct, no defines yet. Signed-off-by: Keith Packard <keithp@keithp.com>
* altos/lpc: Get USART runningKeith Packard2013-05-17
| | | | | | Adds a simple demo thread that spews data to the serial port Signed-off-by: Keith Packard <keithp@keithp.com>
* lpc: Initial lpcxpresso bitsKeith Packard2013-05-17
This gets the LPC11U14 clock set to the PLL and blinks the LED. Signed-off-by: Keith Packard <keithp@keithp.com>
