* Changed nzmichaelh's initial DMA interface to be more flexible.Marti Bolivar2010-12-306-59/+153
| | | | | Some bugfixes in the external interrupt code were found along the way. Defines for nonexistent registers removed from nvic interface.
* nzmichaelh's pull request mods compile and upload.Marti Bolivar2010-12-2811-19/+256
| | | | renamed SysTick_Handler back to SysTickHandler since all of our linker magic/lanchon-stm32 depends on that name. added backup register support in order to test independent watchdog support; it seems to work. next major test target is DMA support.

| * Enable external interrupts on all Maple GPIOs.Perry Hung2010-09-227-264/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
| * Add PWM_OPEN_DRAIN option to pinMode()Perry Hung2010-09-212-1/+5
| | | | | | | | | | | | Allow for alternate function open drain output mode to be accessed through the wirish interface. This allows for open drain to be used on PWM pins.

| * Enable USB auto-reset in a hard fault.Perry Hung2010-09-176-93/+49
| | | | | | | | | | | | | | | | 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.
| * Improve reset reliability on OS X.Perry Hung2010-09-171-0/+7
| | | | | | | | | | | | | | The USB reset scheme on OS X is unreliable. Adding a little bit of sleep seems to make it much more reliable. This will probably do until we get a chance to rewrite the USB stack and redo the whole auto-reset scheme...
