The NRF52 series can map digital signals to any physical pin which
makes it challenging to associate pin names with hardware instances.
pinmap_ex:
Keep track of which hardware instance is in use and what pins are
associated with it. Currently only supports I2C and SPI, but
provides a mechanism for allocating the shared I2C/SPI hardware.
PeripheralPinsDefault:
Optional pin map for pre-assigning hardware instances at compile
time. This makes it easier to optimize hardware utilization.
* Add NRF_SD_BLE_API_VERSION=5 macro to MCU_NRF52832 target
* Added initial Softdevice v5 API support for nRF5XPalGattClient.cpp
* Added initial Softdevice v5 API support for nRF5xGap.h
* Added initial Softdevice v5 API support for nRF5xGattServer.cpp
* Make sure the ah() hash function used by the security manager is declared with C linkage
* Removed 'ARM porting pending' checks in Nordic SDK
* Added BLE configuration to mbed_lib.json for NRF52x targets
* Migrated APIs and events model for Nordic SDK14.2 & SD API v5 in btle.cpp; adopted polling dispatch model
* Migrated APIs and events model for Nordic SDK14.2 & SD API v5 in nRF5xn.cpp
* Migrated APIs and events model for Nordic SDK14.2 & SD API v5 in nRF5xGap.cpp
* Added const qualifier to hwCallbacks's p_ble_evt parameter in nRF5xGattServer
* Add workaround to enable Radio Notification module from Nordic SDK
* Disabled SWI1 interrupt manually from SWI driver module
* Added missing include directive for "nrf_nvic.h" in ble_radio_notification.c
* Set correct number of custom UUIDs
* Adjust Softdevice RAM requirements for NRF52832/S132
* RAM settings for the application were adjusted as follow:
* Start: 0x20003800
* Size: 0xC800
* Adjust Softdevice RAM requirements for NRF52840/S140
* RAM settings for the application were adjusted as follow:
* Start: 0x20003700 (was 0x20003000)
* Size: 0xC900
* Added 3dBm as a permitted TX Power value for NRF52832
* Fix address type recovery in GAP
* Return min non-connectable adv interval compatible with infrastrcture's expectations
* Moved BLE driver from TARGET_SDK_14_2/FEATURE_BLE to TARGET_SDK_14_2/TARGET_SOFTDEVICE_COMMON/ble
* When multiple TRNG objects are initialized, destroying the first
object will turn the TRNG off for the other objects. This fix
adds a counter to ensure that only when the last object is
destroyed will it cause the TRNG to be disabled.
* The corner case where a user request 0 bytes is correctly handled
and will now return immediately.
Add fstorage and fds from Nordic SDK for SoftDevice compatible
flash storage. Mbed HAL flash API mapped to use fstorage API
to ensure write and erase doesn't conflict with BLE operation.
Various bug fixes:
* Moved SPIM3 location in vector table based on new location in SDK 14.2.
* Updated vector table entries and size in startup code and linker scripts.
* Added missing vector table RAM section to IAR linker script.
Ability to swap SoftDevices using the mbed configuration system.
For example, build NRF52840_DK without SoftDevice:
"target_overrides": {
"*": {
"target.MERGE_SOFT_DEVICE": false,
"target.extra_labels_remove": ["SOFTDEVICE_COMMON", "SOFTDEVICE_S140"],
"target.extra_labels_add": ["SOFTDEVICE_NONE"]
}
}
Pinned down vector table to beginningn of RAM.
Critical section enter/exit is now delegated to Nordic SDK's
sd_nvic_critical_region_enter
sd_nvic_critical_region_exit
When the SoftDevice is not included these functions map to
__disable_irq
__enable_irq
Initial commit for separating NRF52 code from the NRF51 and for
combining the NRF52832 and NRF52840 SDK to version 14.
nRF5_SDK_14.2.0_17b948a.zip has been used as baseline.
The folders in SDK/components:
* ble
* boards
* device
* drivers_nrf
* libraries
* softdevice
have been copied to TARGET_NORDIC/TARGET_NRF52/TARGET_SDK14.
Each folder contains a README.md file describing any modifications
made to that particular folder. Most common operation is deletion
of files.
If the need arise in the future the missing files can be added again.
The SoftDevices have been moved to TARGET_SOFTDEVICE_x folders for
flexible selection.
ble.h has been renamed to nrf_ble.h to avoid namespace clash with
mbed OS BLE.
