Board-specific values; corresponding QA test generalizations.
Various board-specific #defines and arrays of pins added.
For the changelog (some of this information predates this commit):
* wirish/boards.h now declares the following arrays of pin numbers:
* boardPWMPins - PWM-capable pins
* boardADCPins - ADC-capable pins
* boardUsedPins - pins already in use, e.g. BOARD_BUTTON_PIN
It also declares a bool boardUsesPin(uint8 pin) function for
convenient testing of whether a pin is in use.
* wirish/boards/*.h now define:
* BOARD_USART1_TX_PIN
* BOARD_USART1_RX_PIN
* BOARD_USART2_TX_PIN
* BOARD_USART2_RX_PIN
* BOARD_USART3_TX_PIN
* BOARD_USART3_RX_PIN
* BOARD_NR_GPIO_PINS (renamed from NR_GPIO_PINS)
* BOARD_NR_USARTS (renamed from NR_USARTS)
* BOARD_NR_PWM_PINS
* BOARD_NR_ADC_PINS
* BOARD_NR_USED_PINS
* wirish/boards/maple_native.h now defines:
* BOARD_UART4_TX_PIN
* BOARD_UART4_RX_PIN
* BOARD_UART5_TX_PIN
* BOARD_UART5_RX_PIN
(Unfortunately, wirish/boards/maple_RET6.h cannot, since at least
one of the UART4/UART5 pins are used already; this will require layout
changes for a wide-release Maple form factor RET6 board).
* wirish/boards/*.cpp all include the corresponding array definitions.
They all live in flash by default, thanks to the new __FLASH__ macro
in wirish/wirish_types.h, which is a synonym for the existing __attr_flash
#define in libmaple/libmaple_types.h.
The documentation was updated to include this information. It also
gained various FIXME/TODO comments related to its generalization
across boards.
The quality assurance-related examples (examples/qa-slave-shield.cpp
and examples/test-session.cpp) now make heavy use of board-specific
values to ensure portability.
