Created (a new) PPP interface for PPP service. Removed lwip
dependencies to PPP (memory allocations etc.). Moved PPP
configuration options away from lwIP mbed_lib.json to new
PPP service. For backwards compatibility, using the old
options is also currently supported.
PPP service encapsulates the PPP protocol. PPP interface can be used as
helper class to bind PPP protocol with network stack (similar to
EMAC and L3IP interface). Added PPP interface to onboard network
stack class.
Created PPP service class that encapsulates the PPP protocol.
Class is similar to EMAC and L3IP classes with additional methods
to read IP and DNS server addresses negotiation using PPP and
to set PPP specific parameters (file handle for modem access etc.).
PPP service can use on its own thread or in run in mbed os event
Queue thread.
Added ppp_nsapi.cpp module that implements the nsapi_ppp.h
services.
Added ppp_nsapi.cpp module that implements the nsapi_ppp.h
services.
Fix SPI module index error in modidx_ns_tab table in CLK_SetModuleClock_S().
Need to update secure image for this bugfix.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-spi/
SPI - init/free test all pins.
M451 series can classify by M45xD/M45xC and M45xG/M45xE. To support this
classification:
1. Create TARGET_M45xD_M45xC and TARGET_M45xG_M45xE targets.
2. Mark NUMAKER_PFM_M453 belongs to TARGET_M45xG_M45xE by 'extra_labels_add'
in targets.json.
3. Fix pin name table according to the classification.
4. Fix pinmap table according to the classification.
MOSI1/MISO1 are used in second bit of 2-bit transfer mode and cannot be used
for normal MOSI/MISO. Remove them from pinmap.
This is also to fix FPGA CI test mbed_hal_fpga_ci_test_shield-spi/
SPI - basic test.
Without free-up of peripheral pins, peripheral pins of the same peripheral may
share by multiple ports after port iteration, and this peripheral may fail with
pin interference.
In Nuvoton, only new-design chips support GPIO input pull-high/pull-low modes.
Targets not supporting this feature are listed below:
- NUMAKER_PFM_NANO130
- NUMAKER_PFM_NUC472
- NUMAKER_PFM_M453
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.
