* 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>
* stm32f2/gpio.c: Fix some bugs.Marti Bolivar2012-05-311-3/+3
| | | | | | | Make gpioh.regs actually point to GPIOH_BASE. Properly AND out flag bits in gpio_set_modef(). Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* <libmaple/gpio.h>: Fix gpio_write_bit().Marti Bolivar2012-05-311-1/+1
| | | | | | | It's exactly wrong -- val=0 makes the pin high, and val=1 makes it low. 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>

* libmaple/fsmc.h: Don't use BIT().Marti Bolivar2012-05-311-23/+23
| | | | | | | As fsmc.h doesn't include util.h or libmaple.h, these usages are actually in error. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* Make usart_irq() __always_inline.Marti Bolivar2012-05-081-1/+1
| | | | | | | Compiling with -Os can prevent this from inlining, and it's an IRQ handler, so the space is worth spending. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* Fix a bunch of Doxygen file-level comments.Marti Bolivar2012-05-0865-85/+92
| | | | | | | | | | | | | Fix @file in many places. Also fix up the descriptions where it's appropriate. This standardizes the @file formatting across the library to explicitly include any parent directories up to the repository root. Besides being nice, this will hopefully let us manage Doxygen's XML output so as to make extracting series-specific pieces via Breathe in the leaflabs-docs repo possible.

| | | | | | | | | | Change the values of the STM32_F1_LINE_xxx macros to match the part number better (so performance line, or F103s, now have STM32_F1_LINE_PERFORMANCE==3, F100s have STM32_F1_LINE_VALUE==0, etc.).
