1 ================ Revision history ============================================
\r
3 - Use ARM CMSIS version 4.2.0.
\r
4 - emlib: New style version macros in em_version.h.
\r
5 - usb: Added support for isochronous endpoint transfers.
\r
8 - EFR32 header release.
\r
12 - CMSIS: No changes.
\r
13 - Device: Added device header files for new Happy Gecko family.
\r
14 - Device: Corrected RF_GPIO0_PORT macro in EZRLG/WG part header files.
\r
15 - emlib: Added new style family #defines in em_system.h, including EZR32 families.
\r
16 - emlib: Fixed I2C_FREQ_STANDARD_MAX macros.
\r
17 - emlib: Fixed bug in MSC_WriteWord which called internal functions that were
\r
18 linked to flash for armgcc. All subsequent calls of MSC_WriteWord
\r
19 should now be linked to RAM for all supported compilers. The
\r
20 internals of MSC_WriteWord will check the global variable
\r
21 SystemCoreClock in order to make sure the frequency is high enough
\r
22 for flash operations. If the core clock frequency is changed,
\r
23 software is responsible for calling MSC_Init or SystemCoreClockGet in
\r
24 order to set the SystemCoreClock variable to the correct value.
\r
25 - emlib: Added errata fix IDAC_101.
\r
29 - emlib: Added errata fix EMU_108.
\r
30 - emlib: #ifdef's now use register defines instead of a mix of register and family defines.
\r
31 - emlib: Added a case for when there are only 4 DMA channels available:
\r
32 Alignment was (correctly) defined at 7 bit, but got asserted for 8 bit, leading
\r
33 to unpredicatable tripped asserts.
\r
34 - emlib: Added USART_INITPRSTRIGGER_DEFAULT defined structure to support HWCONF.
\r
35 - emlib: Added support for LFC clock tree.
\r
36 - emlib: Added CMU_USHFRCOBandSet() and CMU_USHFRCOBandGet().
\r
37 - usb: Replaced USB_EP0_SIZE and USB_MAX_EP_SIZE macros with new versions which
\r
38 have correct values for low speed/full speed/endpoint types.
\r
41 - Device header release only. Added part headers for EZR families EZR32LG
\r
45 - CMSIS/Device/emlib: No changes.
\r
46 - usb: Added support for Happy Gecko USB LEM (Low Energy Modes).
\r
47 - usb: Fixed bug in suspend powersave mode implementation.
\r
50 - New and updated headers for the Happy Gecko family.
\r
51 - emlib: Added support for Happy Gecko including support for the new oscillator USHFRCO.
\r
52 - emlib: Added MSC_WriteWordFast() function. This flash write function has a similar
\r
53 performance as the old MSC_WriteWord(), but it disables interrupts and
\r
54 requires a core clock frequency of at least 14MHz. The new MSC_WriteWord()
\r
55 is slower, but it does not disable interrupts and may be called with core
\r
56 clock frequencies down to 1MHz.
\r
57 - emlib: Fixed a bug in EMU_EnterEM4() that set other EM4 configuration bits to 0
\r
59 - emlib: Added EMU_EM23Init().
\r
60 - emlib: Fixed a bug in CMU_FlashWaitStateControl() where it failed to set the
\r
61 required wait-state configuration if the MSC is locked.
\r
62 - emlib: Added EMU interrupt handling functions.
\r
63 - emlib: BURTC_Reset() changed to use async reset RMU_CTRL_BURSTEN instead of
\r
64 reset value writeback. This makes the function independent of a selected
\r
66 - emlib: BURTC_Sync() now returns without waiting for BURTC->SYNCBUSY to clear
\r
67 when no clock is selected in BURTC_CTRL_CLKSEL.
\r
68 - emlib: Fixed assertion bug in ACMP_ChannelSet() that checked the negSel parameter
\r
69 against the wrong upper bound.
\r
70 - usb: Added support for Happy Gecko USB peripheral.
\r
71 - usb: Improved USB cable plug/unplug robustness.
\r
74 - This release contains headers etc. for the Happy Gecko family.
\r
77 - Support for new part numbers EFM32GG900F1024, EFM32GG900F512,
\r
78 EFM32LG360F256 and EFM32WG360F256.

\r
86 - usb: Fixed max FIFO size limit for device mode.
\r

\r
88 - usb: Added configurable VBUSEN pin usage to support hw without VBUS switch.
\r
91 - emlib: Corrected fix for Errata EMU_E107.
\r
94 - New part header file folder structure.
\r
95 Header files are now in this path:
\r
96 Device/SiliconLabs/EFM32<FAMILY>/Include/efm32<family><partno>.h
\r
97 Old folder structure is still present for backward compatibility reasons.
\r
98 Device/EnergyMicro/EFM32<FAMILY>/Include/efm32<family>_cmu.h
\r
99 The same change of path applies to all startup and linker files:
\r
100 Device/SiliconLabs/EFM32<FAMILY>/Source/...
\r
101 - emlib: Updated license texts.
\r
102 - emlib: Removed unnecessary fix for Wonder Gecko.
\r
103 - emlib: Updated LFXO temperature compensation in CHIP_Init().
\r
104 - emlib: Changed LESENSE_ScanStart, LESENSE_ScanStop, LESENSE_DecoderStart,
\r
105 LESENSE_ResultBufferClear and LESENSE_Reset functions to wait until
\r
106 CMD register writes complete in order to make sure CMD register writes do
\r
107 not break each other, and for register values to be consistent when
\r
108 returning from functions that write to the CMD register.
\r
109 - emlib: Added fix for Errata EMU_E107.
\r
110 - emlib: Added family to SYSTEM_ChipRevision_TypeDef.
\r

\r
117 - emlib: Added function DAC_ChannelOutputSet.
\r
118 - emlib: Fixed MSC_WriteWord to not use WDOUBLE if LPWRITE is set.
\r
119 - usb: Fixed bug which could cause malfunctioning when prescaling core clock.
\r
120 - usb: Updated license terms.
\r
121 - usb: Fixed potential EP sram partitioning problems.
\r
122 - usb: Allow 64 and 32 byte EP0 max packetsize.
\r
123 - usb: Fixed bug in USBTIMER_Start(), added check on timeout value of 0.
\r
124 - usb: Fixed setting USB device state on USB reset from suspend.
\r
125 - usb: Added support for composite devices in the device stack.
\r
126 - usb: Made special provisions for passing USB-IF "Powered Suspend" test.
\r
129 - Added Zero Gecko family header files.
\r
130 - Added MEMINFO_FLASH_PAGE_SIZE to DEVINFO structure.
\r
131 - emlib: Fixed bug regarding when MEMINFO in DEVINFO was introduced.
\r
132 The correct crossover is production revision 18.
\r
133 - emlib: Fixed bug in WDOG_Feed which does not feed the watchdog if the watchdog
\r
134 is disabled. Previously, the watchdog was broken after WDOG_Feed fed it
\r
135 when it was disabled.
\r
136 - emlib: Fixed issue in em_i2c.c, which should set the NACK bit in the I2C CMD
\r
137 register for the next to last byte received. The exception is when only
\r
138 one byte is to be received. Then the NACK bit must be set like the
\r
139 previous code was doing.
\r
140 - emlib: Added function BURTC_ClockFreqGet in order to determine clock frequency
\r
142 - emlib: Fixed bug in BURTC_Reset which made a subsequent call to BURTC_Init hang.
\r
143 - emlib: Added support for the IDAC module on the Zero Gecko family, em_idac.c/h.
\r
144 - emlib: Fixed bug in DAC_PrescaleCalc() which could return higher values than
\r
145 the maximum prescaler value. The fix makes sure to return the max prescaler
\r
146 value resulting in possible higher DAC frequency than requested.
\r
147 - emlib: Fixed I2C_BusFreqSet to use documented values for Nlow and Nhigh values,
\r
148 and do not decrement the div(isor) by one according to the formula because
\r
149 this resulted in higher I2C bus frequencies than desired.
\r
150 - usb: Increased robustness when plug/unplug-ing the USB cable rapidly.
\r
151 - usb: Changed implementation of usb string macro, wchar_t is no longer used.
\r
152 GCC commandline options -fwide-exec-charset=UTF-16LE, -fshort-wchar and
\r
153 -Wl,--no-wchar-size-warning are no longer needed.
\r
154 Old version was used like this:
\r
155 STATIC_CONST_STRING_DESC( iManufacturer, L"Energy Micro AS" );
\r
156 New version is used like this:
\r
157 STATIC_CONST_STRING_DESC( iManufacturer, 'E','n','e','r','g','y',' ', \
\r
158 'M','i','c','r','o',' ','A','S' );
\r

215 CMSIS/CM3/DeviceSupport/EFM32/ -> Device/EnergyMicro/EFM32LG/Include
\r
217 - The earlier "core_cm3.c" file is now gone and can be deleted from projects,
\r
218 the functionality has moved into "core_cm3.h" (this header file is included
\r
219 in the part specific header file)
\r
221 - Part specific header file size reduction has been implemented. The most common
\r
222 peripheral definitions have been moved into separate files, for instance a
\r
223 standard CMU implementation will be in defined in the file
\r
224 -> Device/EnergyMicro/EFM32<FAMILY>/Include/efm32<family>_cmu.h
\r
225 For devices without a full configuration of the peripheral, the definitions
\r
226 are kept in the part specific header file.
\r
228 - System files moved to family specific "Source" folder
\r
229 CMSIS/CM3/DeviceSupport/EFM32/system_efm32.c

242 -> Device/EnergyMicro/EFM32<FAMILY>/Source/GCC
\r
244 - Gecko startup file has got a "g" (for Gecko family) appended to filename,
\r
245 i.e. startup_efm32g.s, not startup_efm32.s as earlier. Similar for linker
\r
248 - "efm32lib" has been renamed "emlib" as it will support future Energy Micro
\r
249 devices that are not in the EFM32 families. You will need to change all
\r
250 include files starting with
\r
251 #include "efm32_<peripheral>.h" -> #include "em_<peripheral>.h"
\r
252 in your source code. APIs within peripherals are compatible with earlier
\r
253 "efm32lib" releases.
\r
254 Also see emlib/Changes_emlib.txt file for further updates.
\r
256 - "efm32usb" folder has been renamed to just "usb" for the same reasons as
\r
