From 1e42c8777e04e100d2b1589ae71c6e76a1646eb9 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Wed, 30 Mar 2011 00:55:51 -0400 Subject: 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. --- source/lang/api/isbuttonpressed.rst | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) (limited to 'source/lang/api/isbuttonpressed.rst') diff --git a/source/lang/api/isbuttonpressed.rst b/source/lang/api/isbuttonpressed.rst index dbff0c9..8c350b9 100644 --- a/source/lang/api/isbuttonpressed.rst +++ b/source/lang/api/isbuttonpressed.rst @@ -4,7 +4,8 @@ isButtonPressed() ================= Check whether the board's built-in button (labeled BUT on the -silkscreen) is pressed. +silkscreen) is pressed.
