Fix logic error on replying NACK at the end of transfer.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-i2c/
i2c - test single byte read i2c API.
Better IP initialization sequence:
1. Configure IP pins
2. Select IP clock source and then enable it
3. Reset the IP (SYS_ResetModule)
NOTE1: IP reset takes effect regardless of IP clock. So it doesn't matter if
IP clock enable is before IP reset.
NOTE2: Non-configured pins may disturb IP's state, so IP pinout first and then
IP reset.
NOTE3: IP reset at the end of IP initialization sequence can cover unexpected
situation.
The most suitable place to free up I2C pins is in i2c_free(). Due to
i2c_free() not available in I2C HAL, we free up I2C pins manually by
configuring them back to GPIO.
Without free-up of I2C pins, SDA/SCL pins of the same I2C peripheral may
share by multiple ports due to 'all ports' tests here, and the following I2C
tests would be subject to interference by shared ports.
The Nuvoton targets listed below don't support input pull-up/pull-down mode
and so are skipped for test:
- NUMAKER_PFM_NANO130
- NUMAKER_PFM_NUC472
- NUMAKER_PFM_M453
Calls to Timer::attach() are inlined in order not to use floating-point
library functions calls given Timer::attach_us() expects an integer
for the callback interval.
* Create new `s_timestamp_t` type to specify timestamp is seconds
* Alter `attach()` API to expect `s_timestamp_t` for interval value
* Create helper macro to convert seconds to milliseconds and help code
readability
* Modify Greentea tests accordingly
When AT+CGML is used to retrieve list of SMS stored in modem inbox,
every message has an associated index. ETSI TS 127 005 v7.0.0 does not
specify what is the allowed range of such indices - all it says is
"integer type; value in the range of location numbers supported by the
associated memory".
Usually, AT modems use positive indexes (starting at 1). Quectel BG96
modem takes a different approach, indexing messages starting at 0.
Current implementation of `AT_CellularSMS::list_messages()` considers
index 0 invalid and ignores such message, effectively making it
impossible to access using mbed-os API.
This commit changes the behavior so that value of 0 is handled as any
other positive message index.
Currently, create_pdu receives a destination address without '+' prefix,
and always sets the "type of address" to "unknown". That means, the
number needs to contain appropriate international number prefix (00/011)
if necessary - which is not the case if the leading + is simply
stripped.
This changes send_sms behavior so that when a SMS is sent to an
international number (indicated by leading +):
- AT+CMGS command receives the number with + prefix,
- created PDU has the "international" flag set.
This prevents RX2 window to be enabled at the same time when repeating
transmission, when QoS repeated TX is in effect. Failure to do so
seems to place the LoRaWAN stack in a state where send() always fails
with WOULD_BLOCK error.
