* Fix hang on usart read overrun.Joseph Birr-Pixton2015-05-271-5/+12
| | | | | | | | | | This is improved on the previous patch: if we get an ORE without RXNE when we don't write a junk byte to our buffer. It also avoids the strange-looking blind read. See issue #107 for more info. Signed-off-by: Joseph Birr-Pixton <jpixton@gmail.com>

* stm32f4: 32bit-float-friendly GCC flagsbnewbold2015-03-031-1/+2
| | | | | | | | | | | | | | This commit makes 'float' (32-bit) the default for floating point constants in the source code, instead of the defaults 'double' (64-bit). Floating point performance is very sensitive to the float vs. double distinction on 32-bit processors, especially Cortex-M4s with a VFP unit for floats but not doubles. In the future it may be wise to make this change for non-hard-fp chips (aka, all the other STM32s) as well, for behavioral consistancy. The warning flag ensures that the frequently used parts of the code base will be less ambiguous, but doesn't cover series-specific code.

* stm32f4: fill in exception handling infrastructurebnewbold2015-03-031-1/+35
| | | | Eg, for HardFault or assert() failures.
* wirish_math: explicit type casts for round()bnewbold2015-03-031-1/+2
| | | | | | | | This is to squash type promotion warnings and ambiguity (float vs. double). A roundf() macro is introduced for use with floats, matching the POSIX/C99 convention.
* stm32f4: add F4-specific IRQ entriesbnewbold2015-03-032-0/+10
| | | | | Perhaps these should be in F4-specific files instead of the shared F2-F4 files?

* stm32f4: add sram_64k_flash_128k linker scriptbryan newbold2015-03-011-0/+5

|
* wirish/Print: explicit double-width constantsbryan newbold2015-03-011-6/+6
| | | | | | | | | These are to prevent implicit constant conversions from floats to doubles and squelch -Wdouble-promotion warnings. Normally gcc will start by using doubles to represent floating point constants. On 32-bit MCUs with a floating point unit, it is more likely that floats are desired, unless explicitly annotated otherwise.
