* HardwareTimer::setPeriod(): Don't use floating point.Marti Bolivar2012-06-031-3/+3
| | | | | | I can't believe we've been shipping this for so long. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* HardwareTimer.cpp: save some space with an rcc_clk_id hack.Marti Bolivar2012-06-031-97/+26
| | | | | | | | | | | | Since rcc_clk_ids for a peripheral now form a contiguous range by peripheral number, we can infer the rcc_clk_id for a timer given its number (e.g., can calculate RCC_TIMER2 given timerNum == 2). This lets us use timer_foreach() to avoid keeping a table of available timers in HardwareTimer.cpp. The implementation is hackish, but can be fixed up later if need be.

* Bring timer initialization back to init().Marti Bolivar2012-06-024-52/+43
| | | | | | | | | | | | | | Turns out the F1 code was pretty portable after all, so take it from the F1 boards_setup.cpp and stick it back into boards.cpp. The only change needed was to add a call to the newly-minted timer_has_cc_channel() (and this is necessary on F103 XL-density, anyway). Also assert LeafLabs copyright in boards.cpp. We really need to do this throughout the library; it's basically been rewritten since Perry. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Add timer_has_cc_channel().Marti Bolivar2012-06-022-0/+29
| | | | | | | | | This is a convenience function for deciding whether a timer supports a particular capture/compare channel. It's necessary because of those nuisance "general purpose" timers that only have a subset of the channels. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Sort the rcc_clk_id enumerators semi-alphabetically.Marti Bolivar2012-06-022-77/+77
| | | | | | | | | | | | | | | | Only semi-alphabetically because peripherals are kept together (so the UARTs sort as if they were USARTs). Advantages: - It lets us play numeric comparison and lookup-table hacks, as we now have the property that the rcc_clk_ids for a given peripheral are a contiguous range of integers. - It will hopefully let the compiler emit faster/smaller code for switches over a dev->clk_id. - It's better intuitively.

* Bring back HardwareTimer.Marti Bolivar2012-06-013-23/+104
| | | | | | | | | | | | | | Untested, but the timers work on F2 (see exampes/test-timers.cpp), so I'm hoping this is mostly OK. Note that there's an issue with TIMER2 and TIMER5 on F2: these timers have 32-bit counters, and the HardwareTimer methods are all based on uint16 (like on F1). I'm sorely tempted to keep this as-is; exposing the extra bits is just extra documentation, and the HardwareTimer interface is already way too complicated. The interface should still _work_; it just hides the fact that you're missing out on the extra bits for some of the timers. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* libmaple/stm32.h: Add STM32_TIMER_MASK, STM32_HAVE_TIMER.Marti Bolivar2012-06-013-4/+48
| | | | | | | | | | | | | | | | | | Feature-test macros for dealing with the fact that timer support has holes. STM32_TIMER_MASK is a bitmask where bit n is set when TIMERn is present. STM32_HAVE_TIMER(n) just tests whether bit n is set in STM32_TIMER_MASK. This is necessary because e.g. the STM32F100RB has timers 1-4, 6, 7, and 15-17. Because of this, the usual STM32_NR_whatever won't work, and we use a bitmask instead. For F1 performance line (F103s), STM32_TIMER_MASK can be derived from the density. For F1 value line, I'm not as sure, so just add it for the single MCU we support (the STM32F100RB). Same story for F2: add it for the STM32F207IC. We can fix this up later if necessary.

* Bring back HardwareSerial.Marti Bolivar2012-06-0111-56/+127
| | | | | | | | | | | | | | | | | | | | | | | | To make this happen, we need to have <board/board.h> tell us whether or not it's got each of the USARTs. Do that with BOARD_HAVE_USARTn, for n = 1,...,6. This lets us define HardwareSerial instances only when appropriate, and gets rid of some board-specific hacks we'd accumulated. The new <libmaple/usart.h> now has a convenience function for determining the bus rate by using the appropriate STM32_PCLKx macro, so we can shave a uint32 per instance, which is nice given that they're all going to be in memory. This changes the constructor arguments, but the API only specifies the semantics of the predefined instances, so this is still backwards-compatible. (We should look into storing the instances in Flash -- they don't change, after all.) We don't actually need struct usart_dev's definition in HardwareSerial.h, so replace it with a forward declaration and include <libmaple/usart.h> it in HardwareSerial.cpp instead.

| | | | | | | | This should get replaced with a clean-room MIT licensed version, but pieces of it are ours (notably the bugfixes to the floating point printing routines), so might as well do the copyright thing. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Replace shiftOut(), also fixing a possible bug.Marti Bolivar2012-05-312-32/+29
| | | | | | | | | | | | The current shiftOut() is borrowed from Arduino, and is in an LGPL file. Replace that file with a new MIT-licensed version containing a new implementation. The new version brings the clock line LOW before starting, to make sure that the first pulse is detected if the clock line was previously HIGH. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

This covers all the chips we currently support, but it'll be a nasty surprise if anyone decides to add e.g. connectivity line MCUs (which have more IRQs) in the future.
