- The "SECURITY" Peripheral Register Block has been renamed to "AESCCM" to
|
|
avoid naming collisions.
|
|
- If the name MPU_BASE is already defined, it is undefined in the Device

|
|
- Added support for new EZR32HG family.
|
|
|
|
4.0.0:
|
|
- Use ARM CMSIS version 4.2.0.
|
|
- emlib: New style version macros in em_version.h.
|
|
- usb: Added support for isochronous endpoint transfers.
|
|
|
|
3.20.14:
|
|
- EFR32 header release.
|
|
- USB release.
|
|
|
|
3.20.13:
|
|
- CMSIS: No changes.
|
|
- Device: Added device header files for new Happy Gecko family.
|
|
- Device: Corrected RF_GPIO0_PORT macro in EZRLG/WG part header files.
|
|
- emlib: Added new style family #defines in em_system.h, including EZR32 families.
|
|
- emlib: Fixed I2C_FREQ_STANDARD_MAX macros.
|
|
- emlib: Fixed bug in MSC_WriteWord which called internal functions that were
|
|
linked to flash for armgcc. All subsequent calls of MSC_WriteWord
|
|
should now be linked to RAM for all supported compilers. The
|
|
internals of MSC_WriteWord will check the global variable
|
|
SystemCoreClock in order to make sure the frequency is high enough
|
|
for flash operations. If the core clock frequency is changed,
|
|
software is responsible for calling MSC_Init or SystemCoreClockGet in
|
|
order to set the SystemCoreClock variable to the correct value.
|
|
- emlib: Added errata fix IDAC_101.
|
|
- usb: No changes.
|
|
|
|
3.20.12:
|
|
- emlib: Added errata fix EMU_108.
|
|
- emlib: #ifdef's now use register defines instead of a mix of register and family defines.
|
|
- emlib: Added a case for when there are only 4 DMA channels available:
|
|
Alignment was (correctly) defined at 7 bit, but got asserted for 8 bit, leading
|
|
to unpredicatable tripped asserts.
|
|
- emlib: Added USART_INITPRSTRIGGER_DEFAULT defined structure to support HWCONF.
|
|
- emlib: Added support for LFC clock tree.
|
|
- emlib: Added CMU_USHFRCOBandSet() and CMU_USHFRCOBandGet().
|
|
- usb: Replaced USB_EP0_SIZE and USB_MAX_EP_SIZE macros with new versions which
|
|
have correct values for low speed/full speed/endpoint types.
|
|
|
|
3.20.11:
|
|
- Device header release only. Added part headers for EZR families EZR32LG
|
|
and EZR32WG.
|
|
|
|
3.20.10:
|
|
- CMSIS/Device/emlib: No changes.
|
|
- usb: Added support for Happy Gecko USB LEM (Low Energy Modes).
|
|
- usb: Fixed bug in suspend powersave mode implementation.
|
|
|
|
3.20.9:
|
|
- New and updated headers for the Happy Gecko family.
|
|
- emlib: Added support for Happy Gecko including support for the new oscillator USHFRCO.
|
|
- emlib: Added MSC_WriteWordFast() function. This flash write function has a similar
|
|
performance as the old MSC_WriteWord(), but it disables interrupts and
|
|
requires a core clock frequency of at least 14MHz. The new MSC_WriteWord()
|
|
is slower, but it does not disable interrupts and may be called with core
|
|
clock frequencies down to 1MHz.
|
|
- emlib: Fixed a bug in EMU_EnterEM4() that set other EM4 configuration bits to 0
|
|
on EM4 entry.
|
|
- emlib: Added EMU_EM23Init().
|
|
- emlib: Fixed a bug in CMU_FlashWaitStateControl() where it failed to set the
|
|
required wait-state configuration if the MSC is locked.
|
|
- emlib: Added EMU interrupt handling functions.
|
|
- emlib: BURTC_Reset() changed to use async reset RMU_CTRL_BURSTEN instead of
|
|
reset value writeback. This makes the function independent of a selected
|
|
and enabled clock.
|
|
- emlib: BURTC_Sync() now returns without waiting for BURTC->SYNCBUSY to clear
|
|
when no clock is selected in BURTC_CTRL_CLKSEL.
|
|
- emlib: Fixed assertion bug in ACMP_ChannelSet() that checked the negSel parameter
|
|
against the wrong upper bound.
|
|
- usb: Added support for Happy Gecko USB peripheral.
|
|
- usb: Improved USB cable plug/unplug robustness.
|
|

|
|
- emlib: Corrected fix for Errata EMU_E107.
|
|
|
|
3.20.5:
|
|
- New part header file folder structure.
|
|
Header files are now in this path:
|
|
Device/SiliconLabs/EFM32<FAMILY>/Include/efm32<family><partno>.h
|
|
Old folder structure is still present for backward compatibility reasons.
|
|
Device/EnergyMicro/EFM32<FAMILY>/Include/efm32<family>_cmu.h
|
|
The same change of path applies to all startup and linker files:
|
|
Device/SiliconLabs/EFM32<FAMILY>/Source/...
|
|
- emlib: Updated license texts.
|
|
- emlib: Removed unnecessary fix for Wonder Gecko.
|
|
- emlib: Updated LFXO temperature compensation in CHIP_Init().
|
|
- emlib: Changed LESENSE_ScanStart, LESENSE_ScanStop, LESENSE_DecoderStart,
|
|
LESENSE_ResultBufferClear and LESENSE_Reset functions to wait until
|
|
CMD register writes complete in order to make sure CMD register writes do
|
|
not break each other, and for register values to be consistent when
|
|
returning from functions that write to the CMD register.
|
|
- emlib: Added fix for Errata EMU_E107.
|
|
- emlib: Added family to SYSTEM_ChipRevision_TypeDef.

|
|
- usb: Fixed potential EP sram partitioning problems.
|
|
- usb: Allow 64 and 32 byte EP0 max packetsize.
|
|

|
3.20.2:
|
|
- Added Zero Gecko family header files.
|
|
- Added MEMINFO_FLASH_PAGE_SIZE to DEVINFO structure.
|
|
- emlib: Fixed bug regarding when MEMINFO in DEVINFO was introduced.
|
|
The correct crossover is production revision 18.
|
|
- emlib: Fixed bug in WDOG_Feed which does not feed the watchdog if the watchdog
|
|
is disabled. Previously, the watchdog was broken after WDOG_Feed fed it
|
|
when it was disabled.
|
|
- emlib: Fixed issue in em_i2c.c, which should set the NACK bit in the I2C CMD
|
|
register for the next to last byte received. The exception is when only
|
|
one byte is to be received. Then the NACK bit must be set like the
|
|
previous code was doing.
|
|
- emlib: Added function BURTC_ClockFreqGet in order to determine clock frequency
|
|
of BURTC.
|
|
- emlib: Fixed bug in BURTC_Reset which made a subsequent call to BURTC_Init hang.
|
|
- emlib: Added support for the IDAC module on the Zero Gecko family, em_idac.c/h.
|
|
- emlib: Fixed bug in DAC_PrescaleCalc() which could return higher values than
|
|
the maximum prescaler value. The fix makes sure to return the max prescaler
|
|
value resulting in possible higher DAC frequency than requested.
|
|
- emlib: Fixed I2C_BusFreqSet to use documented values for Nlow and Nhigh values,
|
|
and do not decrement the div(isor) by one according to the formula because
|
|
this resulted in higher I2C bus frequencies than desired.
|
|
- usb: Increased robustness when plug/unplug-ing the USB cable rapidly.
|
|
- usb: Changed implementation of usb string macro, wchar_t is no longer used.
|
|
GCC commandline options -fwide-exec-charset=UTF-16LE, -fshort-wchar and
|
|
-Wl,--no-wchar-size-warning are no longer needed.
|
|
Old version was used like this:
|
|
STATIC_CONST_STRING_DESC( iManufacturer, L"Energy Micro AS" );
|
|
New version is used like this:
|
|
STATIC_CONST_STRING_DESC( iManufacturer, 'E','n','e','r','g','y',' ', \
|
|
'M','i','c','r','o',' ','A','S' );
|
|
|
|

and source files to use this version. PLEASE READ THE INSTRUCTIONS BELOW
|
|
CAREFULLY.
|
|
|
|

|
|
DSP_Lib, RTOS abstraction layer, support for Cortex-M4, Cortex-M0+
|
|
(Flycatcher) and more. For a detailed overview see
|
|
CMSIS/Documentation/General/html/index.html
|
|
|
|
- New file structure of part specific header files deployed according to
|
|
CMSIS_V3 requirements. These are the most important changes, that must be
|
|
changed in project files/Makefiles to update to this new release.
|
|
|
|
Cortex-Mx Core header files
|
|
CMSIS/CM3/CoreSupport -> CMSIS/Include
|
|
Gecko part specific header files
|
|
CMSIS/CM3/DeviceSupport/EFM32/ -> Device/EnergyMicro/EFM32G/Include
|
|
Tiny Gecko part specific header files
|
|
CMSIS/CM3/DeviceSupport/EFM32/ -> Device/EnergyMicro/EFM32TG/Include
|
|
Giant Gecko part specific header files
|
|
CMSIS/CM3/DeviceSupport/EFM32/ -> Device/EnergyMicro/EFM32GG/Include
|
|
Leopard Gecko part specific header files
|
|
CMSIS/CM3/DeviceSupport/EFM32/ -> Device/EnergyMicro/EFM32LG/Include
|
|
|
|
- The earlier "core_cm3.c" file is now gone and can be deleted from projects,
|
|
the functionality has moved into "core_cm3.h" (this header file is included
|
|
in the part specific header file)
|
|
|
|
- Part specific header file size reduction has been implemented. The most common
|
|
peripheral definitions have been moved into separate files, for instance a
|
|
standard CMU implementation will be in defined in the file
|
|
-> Device/EnergyMicro/EFM32<FAMILY>/Include/efm32<family>_cmu.h
|
|
For devices without a full configuration of the peripheral, the definitions
|
|
are kept in the part specific header file.
|
|
|
|
- System files moved to family specific "Source" folder
|
|
CMSIS/CM3/DeviceSupport/EFM32/system_efm32.c
|
|
-> Device/EnergyMicro/EFM32<FAMILY>/Source/system_efm32<family>.c
|
|
|
|
- Startup files moved to family specific "Source" folder
|
|
CMSIS/CM3/DeviceSupport/EFM32/startup/iar/
|
|
-> Device/EnergyMicro/EFM32<FAMILY>/Source/IAR
|
|
CMSIS/CM3/DeviceSupport/EFM32/startup/arm/
|
|
-> Device/EnergyMicro/EFM32<FAMILY>/Source/ARM
|
|
CMSIS/CM3/DeviceSupport/EFM32/startup/cs3/
|
|
-> Device/EnergyMicro/EFM32<FAMILY>/Source/G++
|
|
|
|
- Additional "generic GCC" (such as https://launchpad.net/gcc-arm-embedded or
|
|
http://www.yagarto.de) target startup/linker files
|
|
-> Device/EnergyMicro/EFM32<FAMILY>/Source/GCC
|
|
|
|
- Gecko startup file has got a "g" (for Gecko family) appended to filename,
|
|
i.e. startup_efm32g.s, not startup_efm32.s as earlier. Similar for linker
|
|
files.
|
|
|
|
- "efm32lib" has been renamed "emlib" as it will support future Energy Micro
|
|
devices that are not in the EFM32 families. You will need to change all
|
|
include files starting with
|
|
#include "efm32_<peripheral>.h" -> #include "em_<peripheral>.h"
|
|
in your source code. APIs within peripherals are compatible with earlier
|
|
"efm32lib" releases.
|
|
Also see emlib/Changes_emlib.txt file for further updates.
|
|
|
|
- "efm32usb" folder has been renamed to just "usb" for the same reasons as
|
|
the peripheral library, and all files are now prefixed em_usb.
|
|
Change all header file references from
|
|
efm32_usb<component>.h -> em_usb<component.h>
|
|
Also see usb/Changes_usb.txt for further updates.
|
|
|

|
- USART_RXDATAFULLRIGHT and USART_RXDATAVRIGHT removed for Gecko parts
|
|
- GPIO, renamed INSENSE_PRSSENSE to INSENSE_PRS, similar for INT
|
|
to be consistent with updated documentation (Reference Manual)
|
|
|
|
1.2.1:
|
|
- Fixed DEVINFO calibration shift and mask value for temperature sensor
|
|
fixed in rev.C Gecko devices
|
|
|
|
1.2.0:
|
|
- Added new subgroup "Parts" for all part definitions in doxygen format
|
|
- Removed unused _PARAM_ type definitions, less clutter in header files
|
|
- _CMU_PCNTCTRL_RESETVALUE corrected
|
|
- Added C startup file for IAR, can be used as replacement for assembly file
|
|
- Use #defines instead of "numeric values reentered" in bit field definitions
|
|
- TIMER_PARAM_CCNUM(i) changed to TIMER_PARAM_CC_NUM(i)
|
|
- DPI_CHAN_COUNT changed to PRS_CHAN_COUNT
|
|
|
|
1.1.4:
|
|

|
|
|
|
1.1.3:
|
|
- Removed ADC ROUTE register
|
|
- Renamed DEVINFO DACCAL -> DAC0CAL for all 3 calibration registers and bit
|
|
fields
|
|
- Updated efm32lib with new peripherals
|
|
|
|
1.1.2:
|
|
- Added support for CodeSourcery Sourcery G++ compiler and startup files
|
|
- Device Information page (DEVINFO_TypeDef) - fixed several issues with
|
|
endianness, and other changes to support test revision 4 and above parts.
|
|
This has led to a small incompatibilty with test rev <= 4 and rev A parts,
|
|
in that the flash and sram size bit fields has changed location.
|
|
- DMA_CONTROL_TypeDef changed name to DMA_DESCRIPTOR_TypeDef to be better
|
|
aligned with PL230 manual and code
|
|
- DMA bit fields not supported on EFM32 was removed for the PL230 controller
|
|
- DMA CTRL bit fields renamed to be more consistent with PL230 TRM manual
|
|
- Added additional volatile statements to pointers in DMA Control structure
|
|
- Fixed several registers that were readable, and was marked as __O (output
|
|
only)
|
|
|
|
1.1.1:
|
|
- Fixed startup code, CMSIS SystemInit cannot update global variable
|
|
|
|
1.1.0:
|
|
- Note - some register bit field updates in this release are _not_ backward
|
|
compatible
|
|
- Updated register bit fields to comply with documentation updates, i.e.
|
|
reference manual version > 0.83
|
|
- Apply patch to CMSIS core for GCC issues
|
|
- Added DMA_CONTROL_TypeDef control block for PrimeCell PL230 DMA controller
|
|
- Added ROMTABLE PID / CHIP revision table and masks
|
|
- Revised and updated Device Information page structure "DEVINFO page"
|
|
This structure is ONLY valid for rev.B production devices
|
|
- GPIO EXTIPSEL bit field marked "16" changed to 15 (bug correction)
|
|
- Added more bit fields to TIMER_ROUTE registers
|
|
- Cosmetic updates in doxygen comments and copyright statements
|
|
|
|
1.0.4:
|
|
- ACMP INPUTSEL bit fields changed from ohm rating to res-n,
|
|
- Added bit-band base addresses for peripherals and sram
|
|
|
|
1.0.3:
|
|
- ADC SCANMODE and SCANCTRL bit field updates and corrections
|
|
- Moved Readme.txt and Changes.txt to CMSIS/Readme-EFM32.txt and
|
|
CMSIS/Changes-EFM32.txt
|
|
- CCPEN and CDTIPEN splitted in TIMER_ROUTE
|
|
- EMVREG in EMU_CTRL enumeration changed
|
|
- LCD DISPCTRL volatage levels are part specific, changed settings changed to
|
|
reflect this
|
|
- Added "UL" (unsigned long) to some bit fields giving warnings due to sign
|
|
conversion
|
|
|
|
1.0.2:
|
|
- Corrected revision numbers in file headers
|
|
- Removed example code that was moved into BSP/DVK installer package
|
|
|
|
1.0.1:
|
|
