* Cleaned up wirish/time, some interrupt handling refactoring:Perry Hung2010-08-047-61/+42
| | | | | | | | | Fixed millis(), it was just wrong, before. Added micros(), not extensively tested. New implementation of delayMicroseconds(). Should be more consistent now. Added a handful of nvic routines to enable/disable interrupts. Cleaned up systick
* Turn off MAPLE_DEBUG by default.Perry Hung2010-08-041-1/+1
| | | | | Save space on debug strings, performance. Perhaps we should consider some form of user-facing assert.
* New usart implementation:Perry Hung2010-08-045-252/+186

* rename clock selection registerbnewbold2010-07-242-4/+4
| | | | | | | This is just a change of macro name with zero impact on the actual binary. Looking at page 87/1003 of the STM reference manual, bits [0:1] are the SW register which is modifiable by software, while [2:3] are SWS and are set only by hardware.

* good quality vga leaf logo; usb+systick disabledbnewbold2010-07-203-34/+404
| | | | | refactored timers and added interrupt behavior. see notes and comments... also includes a crude vga hack that doesn't use timers.
* 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.

* first approach at modding the reset schemeAJM2010-06-093-31/+47
| | | | now we reset from recv bytes. After receiving the DTR/RTS toggle the next byte in from usb is parsed as the program_delay. For now, this just delays the reset for a period to close the serial port gracefully. Later, this delay will perhaps inform the bootloader of how long to live for...

* libcs3 refactor mergePerry Hung2010-05-281-3/+4
| | | | | | | | | | | | | | | | Removed dependency on libcs3.a because Codesourcery does not provide the source for it. We now link against a modified libcs3-lanchon-stm32.a built from parts in public domain from Lanchon, and a start_c.c from Codesourcery that is licensed under a permissive license. Also removed all of the extra linker cruft from the stm32conf directory. The linker files now live in support/ld The openocd scripts now live in support/openocd The udev rules and copy-to-ide scripts now live in support/scripts The source lives in support/ld/libcs3-lanchon-stm32.tar.gz

Not extensively tested for interactions between peripherals. commit bf4fc3bf6bc02342ae508b52fb4515d361d626f6 Author: Perry Hung <iperry@alum.mit.edu> Date: Sat Apr 24 03:16:35 2010 -0400 Upper level libmaple interface Added a C++ HardwareSPI class to access the SPI interface. See HardwareSPI.cpp and HardwareSPI.h for documentation. commit 17e0e5edde60e9bf2aa4d52173ad7d47d6d6da75 Author: Perry Hung <iperry@alum.mit.edu> Date: Thu Apr 22 02:36:01 2010 -0400 Initial SPI Polling implementation. Initial commit of a polling-based SPI driver. The driver is limited to synchronous, blocking sends and a 8-bit data frame format. Tested on SPI1 and SPI2. Other peripherals are temporarily disabled, and the rx function is untested until I find a good peripheral to test everything on.
