* Enable external interrupts on all Maple GPIOs.Perry Hung2010-09-224-177/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Extend the wirish attachInterrupt() and detachInterrupt() interface to work with all GPIOs. Note: The STM32 external interrupt lines are multiplexed between GPIO ports. While any GPIO can be used as an external interrupt, not all of them can be used at the same time. Each EXTI[n] line selects between PA[n], PB[n], PC[n], etc. For example, line EXTI5 can be used with STM32 pins PA5, PB5, or PC5, but not all at the same time. See table: EXTI Line Maple Pin STM32 Pin 0 D2 PA0 0 D27 PB0 0 D15 PC0 1 D3 PA1 1 D28 PB1 1 D16 PC1 2 D1 PA2 2 D17 PC2 2 D25 PD2 3 D0 PA3 3 D18 PC3 4 D10 PA4 4 D19 PC4 5 D13 PA5 5 D4 PB5 5 D20 PC5 6 D12 PA6 6 D5 PB6 6 D35 PC6 7 D11 PA7 7 D9 PB7 7 D36 PC7 8 D6 PA8 8 D14 PB8 8 D37 PC8 9 D7 PA9 9 D24 PB9 9 D38 PC9 (BUT) 10 D8 PA10 10 D29 PB10 10 D26 PC10 11 D30 PB11 12 D31 PB12 13 D32 PB13 13 D21 PC13 14 D33 PB14 14 D22 PC14 15 D34 PB15 15 D23 PC15
* Fix improper interrupt clearingPerry Hung2010-09-221-14/+4
| | | | | | | Interrupts should be cleared by writing to the interrupt clear-enable register (ICER). This commit fixes an improper read-modify-write on NVIC_ICER[n] that incorrectly cleared interrupt-enable bits on non-designated channels.

* Enable USB auto-reset in a hard fault.Perry Hung2010-09-174-87/+39
| | | | | | | | Redirect thread-mode execution to a fail routine which throbs the LED to indicate a hard fault. Because the fail routine runs in thread mode with interrupts on, USB auto-reset should now work. Test by executing some bogus instruction (e.g. *(volatile int*)0xf34fdaa = 0;) and check that the auto-reset continues to work.

* working serialUSB with timeoutbnewbold2010-07-192-0/+7
| | | | | | | | | | | as a temporary workaround for the fact that SerialUSB is often blocking, this crude implementation makes the low-level C usbSendBytes function non-blocking (with a return code of bytes sent) and implements a 2ms timeout in the wirish write() function. also adds begin(), end(), getDTR(), getRTS(), pending(). device is still initialized the old fashioned way during init() so that, eg, autoreset will work. includes a simple multi-test program.

* make: Modularize makefiles, add dependency tracking, build-type trackingPerry Hung2010-06-251-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Major build system rewrite. New and exciting: 1. Proper dependency tracking. All source files including header files should be properly tracked and recompiled as necessary when they are changed. 2. Build-type tracking. If the target changes from 'ram' to 'flash,' for example, the build system will force a rebuild rather than incorrectly link modules to a different address. 3. New targets: The old 'ram,' 'flash,' and 'jtag' targets have been replaced with the environment variable MAPLE_TARGET, which controls the link address. Users can either export it to their environment, or pass MAPLE_TARGET on the command-line. Once this is set, sketches can be compiled with 'make sketch,' or simply 'make.' Note: the default is MAPLE_TARGET='flash.' The target 'install' now automagically uploads the sketch to the board using the appropriate method. The 'run' target has been renamed to 'debug.' It starts an openocd gdb server. 4. Odds and ends: -Verbose and 'quiet' modes. Set V=1 for verbose compilation, the default is quiet. -Object file sizes and disassembly information is generated and placed in build/$(BOARD).sizes and build/$(BOARD).disas, respectively. -Parallel make with -j should speed things up if you have multiple cores.
