* Board-specific values; corresponding QA test generalizations.Marti Bolivar2011-03-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Final stm32_pin_info design candidate; ADC3 support on Native.Marti Bolivar2011-03-251-2/+2
| | | | | | | | | | | | | | | | | | | | Added an adc_dev to struct stm32_pin_info. This was necessary to add support for the channels on the Native which are only connected to ADC3, but it does add a bunch of NULLs to the PIN_MAPs. I don't think any other peripherals need representation on a per-pin basis. Each peripheral library will be responsible for keeping track of related GPIO ports and bits, and we can throw #defines in to boards/*.h for other things (e.g. BOARD_SPI1_MISO_PIN). Fleshed out the ADC refactor and brought it more in keeping with the new design as it evolves. A couple of other tweaks. Notably: waitForButtonPress() now takes a default argument meaning "wait forever". Removed Maple-specific documentation from core functions in io.h; this information will need to go into the individual board docs files.
* Adding /wirish/boards/ for easier porting; shrank PIN_MAPs.Marti Bolivar2011-03-241-3/+3
| | | | | | | | | | | | | | | | | /wirish/boards/ contains xxx.h and xxx.cpp (for xxx=maple, maple_native, maple_mini, maple_RET6). The headers contain the board-specific #defines that used to live in boards.h (except BOARD_INIT, which was removed). The CPP files contain the PIN_MAP definitions that used to live in boards.cpp, and a proper boardInit() function to replace the old BOARD_INIT macro. This will make it easier to add new boards in the future. struct PinMapping was renamed struct stm32_pin_info, and was moved into a new wirish_types.h. Its external interrupt field was moved into struct gpio_dev, which saves memory by storing an afio_exti_port per port, rather than one per pin. Also rearranged the stm32_pin_info fields to improve packing. Maple's PIN_MAP is now down to below 500 bytes.
* [WIP] GPIO refactor: seems ok, ready for reviewMarti Bolivar2011-03-111-0/+82
