Thomas Kemmer 90253ef7f5 Use high resolution time for Timer::read(). 2018-10-19 11:46:55 +01:00
deepikabhavnani 040f4fe664 Cleanup SPI constructor and add destructor 
_acquire() is not required in constructor, since we are not performing
any operation on SPI bus yet. Just initialize the pins/hw

Destructor is required to clear _owner else SPI format/frequency will not be
set if object is recreated. We do not free SPI bus, but init again in hardware
may or may not change frequency/format.

```
{
    SPI spi1(...);
    spi1.transfer(...);
}
{
    SPI spi1(...);
    spi1.transfer(...);
}
```

Christopher Haster b7b94b31de CRC: Removed assertion on NULL buffer 
When length is zero, the buffer is not accessed. The CRC functions are used
inside several other layers where a 0-length buffer may have meanings in
different contexts and being able to pass 0-length NULL buffers to CRC as a
noop simplifies the code.

Deepika 8d31fc144e Use MbedCRC for LittleFS (0xEDB88320) 
CRC used in LittleFS is Reversed ANSI, hence new polynomial added.
Reversed polynomials perform shift in reverse direction of standard
polynomial, and we do not have option to notify reverse shift to hardware.
Hence this option is available in software only.

adustm 0714ac350f Revert "Dummy cycles count is not an init parameter, but a command parameter."

adustm 2b234c2902 Move _mode from QSPI::configure_format to QSPI::QSPI 
QSPI::configure_format shall not call initialize function.
This way, QSPI::configure_format can be called any time,
only to change the format of commands.
It must contain only parameters for the commands, not for the Init function
 2018-08-22 15:00:20 +02:00
adustm 8d2f426d97 Dummy cycles count is not an init parameter, but a command parameter. 
It can change depending on the chosen command, not only at start.
This way we avoid to launch init function and break the internal status variables.

deepikabhavnani 7885edb671 Template specialization didnt work after addition of default constructor 
Template specialization didn't work after addition of default constructor
for unsupported polynomials. Since the argument type and count are same,
compiler always selects the default constructor.

Kevin Bracey 0f98338153 Improve efficiency and formatting of ITM output 
SerialWireOutput was outputting 1 character per 32-bit write to the
ITM stimulus port. This is inefficient, and causes processing problems
with some viewers due to them receiving 3 NUL bytes between each
desired character.

Rework to allow us to be more efficient, and eliminate those NUL bytes:

* Retain existing mbed_itm_send() and clarify it's a single 32-bit write.
* Add new mbed_itm_send_block() that is appropriate for sending
  character data, and modify SerialWireOutput to use it.
* Move "wait for FIFO ready" check to before the write, rather than
  after.

One minor correction - FIFOREADY is a single bit of the register read.
Don't interpret reserved bits.

Steven Cartmell e0d98bfe2c Adapt MbedCRC class to support Hardware CRC 
- Move CRC polynomial enum into HAL layer, so it's accessible from platform
  implementations

- Add enum to CRC class to indicate which mode the CRC class should use:
  HARDWARE, TABLE, or BITWISE

- Add calls to HAL Hardware CRC API to each of the compute functions when the
  class is in HARDWARE mode.

- Add missing constructor call to template constructor, and remove const from
  delegating constructor.
