* Keep it 80-column clean.Marti Bolivar2011-06-071-14/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | Go through overlong source code lines and convert as many of them as appropriate to be 80-column clean. This mostly affects license headers. Overlong lines are determined by running following from the libmaple base directory: $ ack-grep --nocolor --nogroup --cpp --cc --ignore-dir=usb -- '.{80}' Note that this excludes libmaple's usb subdirectory, which is still full of ST code that doesn't follow the libmaple source code guidelines. Contents of ~/.ackrc (these won't matter, but are included for completeness): --ignore-dir=docs --ignore-dir=build --type-set ld=.ld --type-set rst=.rst --type-set txt=.txt --type-set mk=.mk
* Board-specific values; corresponding QA test generalizations.Marti Bolivar2011-03-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bolivar2011-03-251-16/+12
| | | | | | | | | | | | | | | | | | | | 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 Bolivar2011-03-241-4/+4
| | | | | | | | | | | | | | | | | /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.
* Initial timer refactor.Marti Bolivar2011-03-241-3/+3
| | | | | | | | | | | | | | | Basic PWM works. Had some problems in testing that might be due to USART bugs. HardwareTimer has been removed from the build for now; I will re-implement it in terms of the new libmaple API, but consider it deprecated. Let's come up with something better. Servo is implemented in terms of HardwareTimer, so it also has been temporarily removed from the build. pwmWrite() likely got a little bit less inefficient due to indirection, but the PIN_MAPs shrank by a pointer per PinMapping.
* [WIP] GPIO refactor: seems ok, ready for reviewMarti Bolivar2011-03-111-0/+143
