Add a spi_private.h with a SPI_DEV(), for convenience. Use it in the F1 and F2 implementations. We could probably unify these with an STM32_HAVE_SPI(n) macro, but we'll leave that for the future. Most everything from F1 is portable; F2 has some additional bit definitions and a spi_get_af() routine, but that's about it. Signed-off-by: Marti Bolivar

stm32.h: Soften "missing MCU" errors into warnings.

2012-06-07T07:38:29+00:00

It's not important whether the MCU is specified. What's important is that gets everything it needs -- which it now ensures that it does. Requiring people to do things on a per-MCU basis hurts hackability and is just asking for trouble. On the other hand, it's nice to provide a clue as to why might be giving #errors, so do leave the warnings. People can always hack the header to shut them up if they want.

Minor variations on F2: DMA underrun interrupts, and a status register to hold the notification bits. Signed-off-by: Marti Bolivar

STM32F2: Add EXTI support.

2012-06-04T02:45:41+00:00

Add series headers to keep the base pointers, and (on F2) use SYSCFG to tell exti_do_select() where the EXTI control registers are. No surprises. Signed-off-by: Marti Bolivar

Bring back EXTI on F1, with deprecations for gpio.h on F1.

2012-06-04T02:40:40+00:00

Tested on Maple Mini with examples/mini-exti-test. Changes to Wirish are minor: use the new EXTI types exti_num and exti_cfg (see below) in place of now-deprecated variants in ext_interrupts.cpp. The way I originally did libmaple/exti.h was stupid, and fixing it turned out to be a little disruptive. libmaple/exti.h depends on libmaple/gpio.h (for AFIO), but that's a classic case of exposed implementation detail. So invert the dependency: make gpio.h depend on exti.h. Do this by adding exti_num and exti_cfg to exti.h; these respectively replace afio_exti_num and afio_exti_port. The afio_* variants are now deprecated. (Throw in a typedef and some macros at the bottom of the F1 series/gpio.h for backwards compatibility). Make exti_attach_interrupt() and exti_detach_interrupt() take exti_num/exti_cfg arguments instead of the afio_* variants. Make the EXTI dispatch routines __always_inline to defeat GCC -Os. Many renames throughout libmaple/stm32f1/ to stop using the deprecated names. Also move the previously F1-only gpio_exti_port() function into the public libmaple header. Reimplementing it in terms of rcc_clk_ids lets us deprecate the gpio_dev->exti_port field, which will save space in the future. While we're there, I notice that struct gpio_dev is defined once per series. That's dumb, as it misses the entire point of having device structs: they contain what's portable. So put the F1 version (which has the extra EXTI port field) into libmaple/gpio.h, and add the necessary exti_ports to libmaple/stm32f2/gpio.c. Sigh. We'll get rid of it eventually, at least. Clean up some other mistakes in gpio.h files as well (mostly removing util.h dependency). Sorry for the messy commit. For portability, add a new series-specific exti function, exti_select(). The F1 version in (new) libmaple/stm32f1/exti.c uses AFIO and some new private functionality in libmaple/exti.c and (new) libmaple/exti_private.h to make this convenient. We'll be able to do the SYSCFG equivalent on F2 without any trouble. Signed-off-by: Marti Bolivar
