450c3e00a1 Basic helper routines for CRC 
Note, the CRC block is pretty useless for interoperability.  It only operates on 32bit
chunks, and in a different bit order.  No attempt to make full helpers for compatibility
with other implementations has been done.

536c922577 Modified SSP driver to wait for data to be sent before returning. This is critical when controlling device CS# pins via GPIO. Long-term, it might be better to have a different API that permits this level of control. 2012-06-15 17:20:50 -07:00

62849f043c Add helper function for max clock on HSI for f100 
Based on existing HSI code. Tested with f100c8, on custom board with no
external crystals or resonators.

71a3a7f2b1 Add Device Electronic Signature support. 
Working unique id support, but not 100% convinced that this is the "least surprise"
path.  ST's docs provide the bits from low to high, in 2xu16 and 2xu32.
But to get it back as a "u96" the highest bits should be first?

8d97dbc7c3 Work on scs.h register and also nvic.h. 
ARM Interrupt API (see nvic.h).
ARM SysTick API (see systick.h).
Example using both Interrupt and SysTick and blink LED1/2/3 see systickdemo.c.

e7fbc2220b Added JellyBean Configuration for PinMux, GPIO In/Out (work in progress). 
Added scu driver file scu.c.
Modified Makefile/Makefile.include to generate .map file and use -O2 as optimization.
Modified hackrf-jellybean miniblink.c to enable 1V8 and blink LED1,2&3 with configuration of PinMux and GPIO.

12a73ce052 Use ODR instead of IDR to toggle an output GPIO 
IDR represents the level on pin input while ODR is the value requested by the
programmer. This makes a difference for example when using the output as open
drain.

3b20a5e34e Removed the load address statement from the .bss section. 
Otherwise the linker will complain: "section has both a load address and
a load region"

bf65589183 Support for exception handling in linker scripts. 
This is needed even in plain C when 64 bit variable (e.g. long long int)
arithmetic is used. For example it is required when newlib is compiled with
--enable-newlib-io-long-long.
