* Globally switch style for GPIO config routines.Marti Bolivar2012-06-039-30/+77
| | | | | | | | | | | | | | | | | | | | Stupidly, spi_gpio_cfg() didn't take a spi_dev* argument on F1, because it doesn't matter there. On F2, where we need to set an alternate function when configuring GPIOs for SPI, we need to know the dev. We can't add break backwards compatibility, so we need a new function. However, we've since added a bunch of foo_gpio_cfg() routines, and we don't want confusing asymmetry in the names. So a global style change is needed. (Fortunately, the new functions weren't part of a release, so it's no problem to change their names). Change all foo_gpio_cfg() routines to foo_config_gpios() (or foo_config_gpio(), if there's only one GPIO to configure). For backwards compatibility, make spi_gpio_cfg() on F1 an __always_inline call to spi_config_gpios(). Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* STM32F2: Add timer_get_af().Marti Bolivar2012-06-032-0/+52
| | | | | | | | Pull some code out of the F2 pinMode() into a utility function. This feels generally useful enough to be exposed to the users (it will, for example, make it easier to implement input capture in a clean way). 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.

* 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.

* stm32f2/usart.c: Change some FIXMEs to TODOs.Marti Bolivar2012-06-011-6/+7
| | | | | | I think these are probably unchanged, but we need to make sure. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Bring back HardwareSerial.Marti Bolivar2012-06-011-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | 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. Assert some copyrights. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* STM32F1: Fix nvic_irq_disable_all() on some MCUs.Marti Bolivar2012-05-311-8/+6
| | | | | | | | | | The current implementation only disables the first 64 IRQ lines. 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. We already have the infrastructure to fix it in a clean way, so we might as well do it now. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
