ripped out marti's SystemTick for the sake of simplicity and added a
systick_resume function to libmaple. new example program demonstrates
the functionality, also demonstrates micros()/USB bug
|
| | |
|
| | |
|

|
|
| |
also removed an old ASSERT()

This compiles for both maple and maple_native but is untested.

Sort of ugly changes. Compiles but untested.

This version throws "defined but unused" warnings which could probably
be squashed with #pragma

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
|

| |

| | |
Save space on debug strings, performance. Perhaps we should consider
some form of user-facing assert.

Fixed a bug where the maximum baud rate was incorrectly set to 225000
General cleanup
Use new rcc and nvic APIs

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.

examples code cleanup, more descriptive comments, more notes

refactored timers and added interrupt behavior. see notes and
comments... also includes a crude vga hack that doesn't use timers.

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.

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.

flip flopped back and forth on how much work should be done here. For now its like 5 lines of changes

fixed some blocking issue on serial tx, improperly checking for connection.

current version gets stuck in the isr somewhere. not sure why or where. must debug.

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...

It wasnt used, and was causing a compiler warning to get thrown. It isnt needed, not sure why I added it in the first place

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

added a no-delay usb serial loop to main.cpp as an example. has no problem at 115200 in minicom!

also, removed some old usb file, bootVect.h, which setup the static table for the runtime usb lib that no longer exists and was provided by the bootloader rev 1
