Previously, the echo test followed a flow like the following:
-STEP- -HOST PC- -DEVICE-
0 send _sync
1 echo back _sync
2 send echo_count
3 echo back echo_count
4 send first echo packet
5 echo back echo packet
(repeat echo steps)
However, as noted by issue #6659, this test would somtimes fail between
steps 4 and 5. To ensure each KV pair makes to the correct destination,
we usually write the KV back. Step 4 does not wait for this to happen
and starts sending echo packets. So the device is acting as the "echo
server".
This change makes the host PC the "echo server". The idea being that the
device will be slower and the host pc should always be able to keep up
with it, not the other way around.
SPI pins are not initialized correctly according to the current
SPI mode.
This commit changes how the SPI instance is configured and ensures
that:
1. SPI pins are initialized on each object initialization.
2. SPI pins are reinitialized on each mode or object change.
3. SPI instance is only initialized when a change has occured.
* Updates driver library to v2.3.1 (2018q1) for bugfixes and convenience functions
* Provides library in correct format (2-byte wchar_t flag) for compiling with ARMCC (#6695 uncovered by #6577)
* Reverts to using a statically-allocated packet buffer since malloc is not thread-safe (and the asserts have been turned on)
This commit changes the conversion function to do all the calculation
inside the HAL in ticks instead of microseconds.
The conversion will be done in Mbed OS side.
As SystemCoreClock is not a constant, it can not be used to initialise
the ticker_info_t structure.

Event queue was using its own Timer or LowPowerTimer objects to derive
millisecond tick counts. This is unnecessary in RTOS builds, where the
RTOS is maintaining a tick count.
It also makes more sense to use the actual RTOS tick count, as the
values are being used to compute tick timeouts for RTOS calls. Computing
these RTOS tick delays with a separate timer could conceivably lead to
rounding errors.
Fixes: #5378
- fix compiler warning message of flash_api.c
- fix compiler warning message of startup_ADuCM4050.c
- eliminate absolute address of ROM tables
- add MBED_APP_START and MBED_APP_SIZE to linker scripts
* Consolidated device_has and macros to the main MCU targets.
* Moved errata configuration to mbed_lib.json for HAL implementation.
* Moved clock configuration to mbed_lib.json for HAL implementation.
* Moved UART configuration to mbed_lib.json for HAL implementation.
Instance counter keeps track of how many objects have been
initialized and freed. On the first object the instance is
enabled and on the last object the instance is disabled.
Serial implementation uses UARTE instead of UART peripheral:
* EasyDMA is used for reading and writing data.
* Triple buffering for receiving data.
See README for full description.
When possible, the I2C HAL will now use the TWI driver in SDK 14.
The manual I2C API still maps onto the old TWI peripheral directly
because the TWI driver doesn't provide the needed low-level functionality.
