As per reference manual, closing communication for master receiver
with repeated start requires, after reading second last data byte
(after second last RxNE event):
-Clearing ACK bit (same as non repeated start case)
-Set START bit (instead of STOP bit in non repeated start case)
This is valid for I2C_FIRST_FRAME and I2C_NEXT_FRAME conditions
*Changes*
- Parallel export
- mbed-os tests added
- specified release version (default to 5)
- default tests AND targets dependent on specified release version
uVision4 is no longer maintained by the Keil team (support was stopped
long time ago).
This is why we need to make the uvision exporter able to generate uVision5
projects by default (which is based on software packs).
Also, adding note that the uvision4 exporter is now deprecated and will be
removed in the future.
Following discussion on:
it seems now clear that the transfer API is meant to be used either
with only Rx, or only Tx or Rx and Tx with the same lenth.
Therefore we're removing support of transfers of Rx and Tx with different
lenghts - this makes porting to HAL more direct and simpler.
This commit is highly derived from an existing work from salkinium.
It adds SPI ASYNC support to STM32 F4 devices. This required a small
rework of the structure to have SYNCH and ASYNCH co-exist.
