* Remove reST documentation, attendant updates.Marti Bolivar2011-06-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | The documentation covers topics not specifically relevant to libmaple, so it doesn't make sense for it to be part of the libmaple source distribution. Delete the docs/ tree, and prepare libmaple for use with the new leaflabs-docs repo, which will contain the docs from now on. * README: update to reflect this change * support/doxygen/Doxyfile: This is the old docs/Doxyfile * Makefile: Add a doxygen target * wirish/comm/HardwareSerial.h: fix reference to docs/. The comment informing maintainers that the HardwareSerial interface is documented by hand refers to the docs/ tree, which no longer exists. Update it to refer to the separate leaflabs-docs repository. * support/scripts/copy-to-ide: No longer build the documentation
* Update Print to match Arduino master.Marti Bolivar2011-06-082-60/+51
| | | | | | | | | Add base argument to integral Print methods, defaulting to DEC so as not to break backwards compatibility. Add precision argument to floating-point Print methods. These changes increase compatibility with the Arduino Print implementation.
* Revert "Add wiring_limits.h"Marti Bolivar2011-06-071-49/+0
| | | | | | This reverts commit f960c41b1a50deb3783fb7750a4af86e0cbb0636. Wait until the Wiring spec is complete to merge this into master.
* Add wiring_limits.hMarti Bolivar2011-06-071-0/+49
| | | | | | | | | | | | This file is analogous to the standard C header <limits.h>. It defines various constants within the Wiring language that we consider to be implementation-defined. The current version is a work in progress; more constants may be added as time goes on. The member constants defined in wiring_limits.h are currently limited to the core Wiring language. They do not include implementation-defined values which pertain to the standard Wiring libraries.
* Keep it 80-column clean.Marti Bolivar2011-06-0720-281/+321
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Docs: Fix several board-specific values.Marti Bolivar2011-05-266-9/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Ugh. Fix BOARD_NR_ADC_PINS and boardADCPins on Maple, Maple Mini, and Maple RET6 Edition: Maple and Maple RET6 Ed. don't have ADC on pin 3. Seems likely that the error was due to AIN being missing on the silkscreen. They also have ADC on pin 13. This is not really true due to the voltage drop across the built-in LED. Maple Mini really should not include BOARD_LED_PIN among its ADC pins, since it's not broken out to a header. Fix BOARD_NR_PWM_PINS and boardPWMPins on Maple and RET6 Ed: Both boards falsely include pin 25 as a PWM pin. Maple RET6 Edition also lacks some PWM pins. Fix BOARD_NR_SPI on Maple RET6 Edition: SPI3 uses PB4, which is unusable since it's tied to NRST. This means that SPI3 is not available on the RET6 edition. Decreasing BOARD_NR_SPI to 2 to accomodate this. Leave the BOARD_SPI3_*_PIN defines intact so as not to further clutter the rest of the library with RET6-specific wrinkles.

* adc.c: adc_init() doesn't set the RCC's ADC prescaler.Marti Bolivar2011-05-191-0/+1
| | | | | You have to call rcc_set_prescaler() yourself now. adc_init() never should have been doing that anyway.

* Putting updated HardwareTimer back into the build.Marti Bolivar2011-05-064-405/+244
| | | | | | | | | | | | | | | HardwareTimer was removed from the build when the timer refactor was done; this redoes it in terms of the new timer.h interface. A variety of conflicting or badly designed bits were deprecated or removed. I'm still not satisfied with this interface, as it's going to make life difficult moving forward to high-density chips, where the addition of basic timers means that the capture/compare methods won't apply in some cases. However, we need to get 0.0.10 out the door, so it'll have to do for now. The docs are up to date, and contain a warning that the Wirish API isn't stable and a recommendation to use libmaple proper.

| | | | | | | Got rid of native_sram.h (and native_sram.cpp), and pushed their functionality into maple_native.cpp. Fixed includes in maple_native.h. Fixed includes in fsmc.h.
* SPI refactor.Marti Bolivar2011-04-287-115/+454
| | | | | | | | | | | | | | | | | Still a polling driver, but the libmaple proper interface exposes enough that users enable the various interrupts and define their own IRQ handlers if they feel like it. Wirish HardwareSPI interface was largely redone; it's more like the Arduino implementation now, although there are some differences when I didn't like their API. The old methods are still there, but are deprecated and slated for deletion in 0.1.0. New board-specific values: BOARD_NR_SPI, BOARD_SPIx_NSS_PIN, BOARD_SPIx_MOSI_PIN, BOARD_SPIx_MISO_PIN, and BOARD_SPIx_SCK_PIN, for x from 1 to BOARD_NR_SPI. Documentation was updated appropriately.

* Better debug port support.Marti Bolivar2011-04-258-11/+107
| | | | | | | | | | | - gpio.h: afio_mapr_swj_config() renamed afio_cfg_debug_ports() - [new] wirish_debug.h: disableDebugPorts(), enableDebugPorts() - Maple, Maple Native, and Maple RET6 PIN_MAPs are now larger by 5, have mappings for the extra JTAG/SW pins. Documentation was updated appropriately.

* Compromise Print implementation.Marti Bolivar2011-04-122-42/+117
| | | | | | | | | | | The users really hated the code size requirements for an snprintf()-based Print implementation, but I really hated how bad the old implementation was. Revised version fixes bugs related to printing 64-bit values and has some improved behavior when it comes to printing doubles. Now, instead of happily printing garbage values when large doubles are printed, we try printing "<large double>" or "-<large double>" (depending on sign) when the argument is too big for the old strategy to accommodate.

* Board-specific values; corresponding QA test generalizations.Marti Bolivar2011-03-3015-38/+158
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bolivar2011-03-2514-276/+304
| | | | | | | | | | | | | | | | | | | | 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 Bolivar2011-03-2417-378/+783
| | | | | | | | | | | | | | | | | /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 Bolivar2011-03-2410-507/+338
| | | | | | | | | | | | | | | 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.
